Addendum to SCHEDULE A and SCHEDULE B

Lone Star Oilfield Technology Know How, Training and Support

This Addendum has been jointly prepared by Lone Star and Valin to provide a summary of the Lone Star Technology including know how which is presently expected to be licensed toHengyang Valin MPM Steel Tube Co., Ltd. (the “Valin MPM”) under the Technology Cross License Agreement (TCLA). This Addendum also includes a summary of training which will be made available to the Valin MPM as provided in the TCLA. This Addendum will be added to Schedules A and B of the TCLA. However, this Addendum does not modify, revise or in any way change the terms and conditions of the TCLA or Schedules A and B.

Lone Star will license the Valin MPM to use Lone Star technical know how associated with the manufacture and sale of Lone Star Oil Country Tubular Goods (OCTG) and Line Pipe as further defined in the TCLA. Such know how will be protected by the Valin MPM as Lone Star Confidential Information in accordance with the TCLA. Access to Lone Star know how will be provided through knowledge integration programs, personnel development through exchange and cross training and the sharing of technical papers. Valin will pay the cost of such training as further defined in the TCLA.

Some of the areas in which Lone Star has developed proprietary technology are listed below. Some of the proprietary technology and associated know how has been developed under agreements with one or more third parties. LONE STAR WILL NOT MAKE AVAILABLE TO THE VALIN MPM ANY LONE STAR TECHNOLOGY OR ASSOCIATED KNOW HOW WHICH IS SUBJECT TO VARIOUS RESTRICTIONS AND LIMITATIONS UNDER AGREEMENTS BETWEEN LONE STAR AND THIRD PARTY LICENSORS.

Lone Star has pioneered many of the high-strength OCTG grades used today. Many of these proprietary technologies have resulted from work with industry standard associations, from developing applied technology with leading energy companies and other OEM’s to influence design specifications, and from long and extensive experience with downhole casing string design and installation. Some of the products in which Lone Star has developed proprietary technical knowledge include:

OCTG and Line Pipe Products and Services

1. High-Collapse OCTG

1.1 High-Collapse OCTG are proprietary grade casings designed for oil and gas wells where high external pressures are anticipated. High-Collapse grades are

available in Specified Minimum Yield Strengths (SMYS) from 55 to 125 ksi (380 to 862 MPa). Certain process routings may vary by SMYS to minimize production costs. Processing for High-Collapse OCTG is based on advanced compressive stress technology. The design and fabrication of the High-Collapse grades is based on the development of carbon low alloy steels, as well as a tight control process from steelmaking to the rolling and heat treatment.

1.2 Licensed Know How includes techniques to provide:

(a) Excellent Hardenabilty for Quenched and Tempered grades.

(b) Low residual stresses.

(c) Fully Tempered Martensitic structure for Quenched and Tempered grades.

(d) High Tempering temperature for Quenched and Tempered grades.

(e) Through-wall microstructural homogeneity.

(f) Fine grain structure.

(g) High-impact toughness.

(h) Low wall thickness variation (eccentricity).

(i) Low ovality.

1.3 Advanced compressive stress technology

(a) A library of approximately fifty (50) published papers, covering the production of High-Collapse strength casing by controlling certain product attributes including: circumferential compressive yield strength, residual stress. Processes include radial compression (proprietary), alleviation of the Baussinger Effect from rotary straightening, and dimensional control.

(b) Certain unpublished research, covering the production of High-Collapse strength casing by controlling certain process routes including: radial compression, tube straightening, relieving, annealing and quenching methods.

2. High-Collapse Sour-Service OCTG

2.1 High-Collapse sour-service OCTG are proprietary grade casings designed for oil and gas wells where high external pressures and hydrogen sulfide are anticipated. High-Collapse sour-service grades are available in SMYS from 80 to 95 ksi (552 to 655 MPa). The design and fabrication of the High-Collapse sour-service is based on the development of carbon low-alloy steels, as well as a tight control process from steelmaking to the rolling and heat treatment.

2.2 Licensed Know How includes techniques to provide:

(a) Clean steel.

(b) Deep desulfurization.

(c) Low residual-elements contents (this will require modification of MPM’s scrap sourcing practices).

(d) Tight control of chemical composition range.

(e) Low residual stresses.

(f) Excellent Hardenabilty.

(g) Fully Tempered Martensitic structure.

(h) Through-wall microstructural homogeneity.

(i) Fine grain structure.

(j) High-impact toughness (CVN).

(k) Low wall thickness variation (eccentricity).

(l) Low ovality.

3. High-Strength OCTG

3.1 High-strength OCTG are designed for deep wells service where high strength with good ductility and fracture toughness are required. These specialized products have strengths ranging from SMYS 110 to 150 ksi (758 to 1034 MPa). The increase of the yield strength reduces steel ductility and fracture toughness. Lone Star has developed grades that optimize this trade-off, and ensure high yield strength as well as good ductility and fracture toughness. The toughness of steel can usually be traced back directly to its microstructure. The design and fabrication of the High-Strength grades is based on the development of Cr-Mo steels, as well as a tight control process from steelmaking to the rolling and heat treatment.

3.2 Licensed Know How includes techniques to provide:

(a) Excellent Hardenabilty.

(b) Fully Tempered Martensitic structure.

(c) Through-wall microstructural homogeneity.

(d) Fine grain structure.

(e) High-impact toughness (CVN and KIC).

(f) Low wall thickness variation (eccentricity).

(g) Low ovality.

4. Green Tube manufacture and pipe finishing

4.1 “Green Tube” is a United States Department of Commerce nomenclature for a pipe sold for quenching and tempering and finishing into OCTG. Green tubes are a subset of High-Collapse, High-Collapse sour-service and high-strength OCTG. The design and fabrication of the green tubes is based on the development of carbon low alloy and Cr-Mo steels, as well as a tight control process from steelmaking to the rolling.

4.2 Licensed Know How includes techniques to provide:

(a) Proper chemistry selection.

(b) Clean steel.

(c) Deep desulfurization.

(d) Low residual-elements contents (this will require modification of MPM’s scrap sourcing practices).

(e) Tight control of chemical composition range.

(f) Control of pipe Outside Diameter (OD).

(g) Low wall thickness variation (eccentricity).

(h) Low ovality.

5. Arctic Service Grade OCTG

5.1 Arctic Service OCTG is designed to used in cold environments that need good low temperature toughness to avoid brittle failure. Lone Star´s Low temperature series have been designed to cope with arctic environments and permafrost problems. These specialized products have yield strengths ranging from SMYS 55 to 125 ksi (380 to 862 Mpa). In frigid zones - due to cold embrittlement - high notch toughness at low temperature for casing and tubing is required in order to withstand shock during handling - storage, makeup and running. This technology covers two separate processing routes:

(a) Controlled rolling for lower strength seamless tubulars.

(b) Quenching and tempering for higher strength tubulars.

(c) Lone Star thinks that controlled-rolling technology for skelp for ERW tubulars can be adapted to hot rolling for seamless tubulars to eliminate the quenching and tempering seamless mill usually require even for low-strength arctic-service tubulars SMYS 55-65 ksi (380-483 MPa).

5.2 Licensed Know How includes techniques to provide:

(a) Formulation of toughness targets.

(b) Chemistry selection.

(c) Clean steel.

(d) Deep desulfurization.

(e) Low residual-elements contents (this will require modification of Valin’s scrap sourcing practices).

(f) Tight control of chemical composition range.

(g) Rolling Temperatures and Reduction (SMYS 55 - 65 ksi (380 - 483 MPa).

(h) Excellent Hardenabilty (SMYS 80 - 125 ksi (552 - 862 MPa).

(i) Fully Tempered Martensitic structure (SMYS 80 - 125 ksi (552 - 862 MPa).

(j) Through-wall microstructural homogeneity (SMYS 80 - 125 ksi (552 - 862 MPa).

(k) Fine grain structure.

(l) High-impact toughness (CVN).

(m) Low wall thickness variation (eccentricity).

(n) Low ovality.

6. Critical Service (CO2) Grade OCTG

6.1 Lone Star´s Critical Service tubulars have been designed to face certain CO2 corrosive environments at a relatively low cost. These specialized products have yield strengths ranging from SMYS 55 to 75 ksi (380 to 517 MPa).

6.2 Carbon dioxide (CO2) is a weakly acidic gas, which becomes corrosive when it dissolves in water. Corrosion of carbon steel takes two forms.: 1) Localized Corrosion (pitting, mesa type, flow induced corrosion) and 2) General Corrosion. The CO2 corrosion - sweet corrosion - can be handled using CRAs (Corrosion Resistant Alloys). However, for certain CO2 environments and production conditions, CRA should not be economically justified. Based on specific applications: Lone Star has developed 3 grades for this critical service: 13% Cr, 4% Cr and 1%Cr steel.

6.3 Licensed Know How for these grades includes:

(a) Chemistry selection.

(b) Clean steel.

(c) Deep desulfurization.

(d) Low residual-elements contents (this will require modification of MPM’s scrap sourcing practices).

(e) Tight control of chemical composition range.

(f) Quenching and tempering practices for the 13 Cr Grade.

(g) Quenching and tempering practices for the 4 and 1% Cr grade if required.

(h) Low wall thickness variation (eccentricity).

(i) Low ovality.

7. Special Clearance Drift Diameter OCTG

7.1 The drift diameter is the inside diameter (ID) that the pipe manufacturer guarantees per specifications. Note that the nominal inside diameter is not the same as the drift diameter but is always slightly larger. The drift diameter is used by the well planner to determine what size tools or casing strings can later be run through the casing, whereas the nominal inside diameter is used for fluid volume calculations such as mud circulating times and cement slurry placement calculations.

7.2 Over-size drift diameters permit the use of larger, more efficient drill bit sizes for well construction. The larger hole also provides more room for fishing operations.

7.3 Over-size drifts require better-than-API control of dimensions. Lone Star was the first pipe manufacturer in the world to offer over-size drift casing, and has continued process refinements to broaden the range of tube OD/wall combinations that allow oversize drifts. Lone Star advanced processing techniques for the manufacture and processing of ERW OCTG for oversize drift. Lone Star thinks

portions of these processes are applicable to the manufactures and heat treatment of seamless OCTG.

7.4 Licensed Know How for these grades includes:

(a) Dimensional control during rolling and heat treatment.

8. Non-API Size OCTG for Unique Well Conditions

8.1 As stated above, drift diameter is the inside diameter (ID) that the pipe manufacturer guarantees per specifications. A subset of over-size drift diameters are Non-API Outside Diameter (OD) size OCTG that permit the use of larger, more efficient drill bit sizes for well construction. The larger hole also provides more room for fishing operations.

8.2 Beyond pipe dimensional control for Non-API OD size OCTG products, special attention must be paid to connection design and manufacture to allow interchangeability with API or proprietary connections while maintaining the burst integrity of the Non-API OD pipe.

8.3 Licensed Know How for this product includes:

(a) Dimensional control during rolling and heat treatment.

(b) Threaded connection design.

(c) Threading practice.

9. OCTG for Steam Assisted Gravity Drainage (SAGD) applications.

9.1 Steam Assisted Gravity Drainage (SAGD) is a thermal production method for heavy oil, and bituminous sands, that pairs a high-angle injection well with a nearby production well drilled along a parallel trajectory. The pair of high-angle wells is drilled with a vertical separation of about 5 m [16 ft]. Steam is injected into the reservoir through the upper well. As the steam rises and expands, it heats up the heavy oil, reducing its viscosity. Gravity forces the oil to drain into the lower well where it is produced. Bituminous sands are expected to be a major future source of oil for the Americas, and it is estimated that 80% of these sands will be accessable only by SAGD. Purpose-made and processed tubulars are better for this application that API commodity grade tubulars.

9.2 Casing and connection reqiurements include resistance to combined high compression and bending loads, with fluctating temperatures. SAGD grades are available in SMYS from 55 and 80 ksi (380 and 552 MPa).

9.3 Licensed Know How for this product includes:

(a) Chemistry selection.

(b) Heat Treating practice.

(c) Connection design and threading practice.

10. Enhanced-Burst OCTG

10.1 Manufacturing methods to produce enhanced properties with better than API 5CT wall control. This is an extrapolation of processes used to manufacture ERW tubulars and may not be applicable to MPM.

10.2 Licensed Know How for this product includes:

(a) Pipe hot rolling practice.

(b) 92.5% Minimum Remaining Body Wall (RBW).

(c) 95% Minimum RBW.

(d) Non-Destructive Testing (NDT) testing procedures.

11. Expandable Tubulars

11.1 Expandable tubulars are used in oil and gas drilling to maintain favorable wellbore sizes in wells requiring multiple, or possibly unforeseen, casing strings. The final manufacturing step is performed downhole after the casing string has been cemented in place, but before the cement has set. Expansion after running allows better hydraulics for cementing. Lone Star is currently limited by existing agreements from licensing any third party to use Lone Star Technology and know how related to Lone Star’s current expandable tubular product line. Lone Star will work with MPM to develop an expandable casing product consistent with the forthcoming specification API 5SET (Solid Expandable Tubulars) and subject to the limitations of Lone Star’s existing agreements.

11.2 Licensed Know How includes techniques to provide:

(a) Chemistry selection consistent with API 5SET.

(b) Clean steel.

(c) Deep desulfurization.

(d) Low residual-elements contents (this will require modification of MPM’s scrap sourcing practices).

(e) Control of pipe Outside Diameter (OD).

(f) Low wall thickness variation (eccentricity).

12. High-Toughness Line Pipe

12.1 Formulation of toughness targets.

12.2 Carbon Equivalent and Toughness Targets.

12.3 Advanced Technical Industry Papers.

(a) A library of approximately forty (40) published papers, covering the production of high toughness line pipe from Grades X-42 to X-120. Note that grades above X-80 will not be needed by Valin MPM as Grades above X-80 occur in pipe ODs larger than Valin MPM intends to produce.

(b) Certain unpublished research, covering the production of high-toughness line pipe using accelerated cooling of pipe.

13. Manufacturing and Technical Applications of API (5CT) and ISO (11960) Product Standards.

13.1 In addition to being knowledgeable in API and ISO Standards, certain Lone Star employees occupy several key positions in oil industry tubular standardization organizations:

(a) Chair of API Manufacturers Advisory Group.

(b) Co-Chair of API SC5.

(c) API representative to ISO-TC175 Liaison.

(d) Lone Star knowledge of API 5CT subtleties has already resulted in a more efficient layout of MPM’s large OD OCTG finishing floor.

14. Non-Destructive Testing

14.1 Data Collection/Use for Load Resistance Factor Design (LRFD) casing design.

14.2 Expertise in ISO requirements for Global Standardization.

15. Proprietary down hole casing string design software.

15.1 Lone Star uses three casing string design methods coded into software and is developing a fourth and proposes a fifth. The proposed program would reside on a soft-key accessible website for use by Valin MPM partners.

(a) Industry Common Design Practice (LSS Casing II).

(b) Maximum Load (LSS Casing III).

(c) Equivalent Triaxial Stress (LSS Casing IV).

(d) Load Resistance Factor Design (LSS Casing V under development).

(e) Load Resistance Factor Design II (LSS Casing VI proposed).

15.2 Casings II-V are restricted access by previous license agreements. Lone Star will develop Casing VI for use by Valin MPM subject to any limitations in Lone Star’s existing agreements.

15.3 LRFD-II for high-pressure high-temperature (HP-HT) wells (LSS Casing VI)

(a) LSS Casing VI is proposed new program. It is not intended for license or sale. Although Casing VI will incorporate all of the capabilities of LSS Casing II-IV, it will add Load Resistances Factor Design (LRFD) methodology based on ISO TR-10400.

(b) LRFD II would combine ISO TR-10400 constitutive equations and other proprietary limit state functions with performance parameters to quantify the resistance. Statistical analysis and manufacturing process knowledge are then applied to determining the stochastic performance of the population. Lot performance would evaluated statistically and is understood by considering the manufacturing process.

16. Product Information

16.1 Lone Star Steel Technical Data Books

(a) Lone Star Steel Technical Data Books are the defacto industry standards for all API, OCTG and Line Pipe.

16.2 Databased Tailored product information templates and packets

(a) A Excel-based proprietary software application to generate for product information sheets, an item frequently requested tubular distributors and end-users.

17. Improved threading of API Connections

17.1 API SR22

Users and manufacturers can meet API requirements for connection tolerances and still potentially have connections with very limited leak resistance. This deficiency and API 8-Round connections is now addressed by API SR22 to provide a reliable performance-based connection that is fit for purpose. Gauging methods are changed, leak resistance ratings incorporate the effect of tension, makeup criteria include both torque and position aspects, and connection tolerances are improved.

17.2 SR22 Specifications address dimensions, gauging, coupling surface treatment, thread form, makeup, and optional ID bore provisions. The key API LTC performance parameters are:

(a) turns makeup,

(b) thread taper,

(c) coupling OD and

(d) thread form.

17.3 The number of turns of makeup required varies depending on diameter and grade. Important makeup parameters are:

(a) thread compound and

(b) surface finish to avoid galling (tin plating or phosphating, for example)

(c) and seal clearances in the thread form.

17.4 Tin plating is required on C90 and higher grades for improved leak resistance.

17.5 Advantages of SR22 include:

(a) Quantifiable performance-based rating;

(b) Root Cause Failure Analysis;

(c) Improved accuracy and repeatability of pitch diameter (PD) measurement.

17.6 Licensed Know How includes:

(a) Tooling Specifications.

(b) Software programming for Okuma NC threaders.

(c) Gauging Practice.

18. Star Seal Proprietary Premium and Semi-Premium connections

18.1 Star Seal-CDC (Casing Drilling Connection) (Semi-Premium)

(a) Casing Drilling is a process that uses standard oilfield casing to drill the well and then leaves it in place to case the well. This process makes it possible to speed up drilling 20 to 30 percent or more, by eliminating drill-string tripping and the problems associated with it. Drill bits and other downhole tools are lowered and retrieved via wireline inside the casing and latched to the bottom-most joint of casing. Casing Drilling is used for surface casings string for certain offshore wells in around the Pacific Rim and several niche drilling applications in North America.

(b) Star Seal-CDC is field-proven connection specifically designed balance the higher torque requirement of casing drilling with the economics required casing drilling string in the North American market.

(c) Lone Star conducted connection evaluation and supplied the casing string for the first well drilled from a dedicated casing drilling rig.

18.2 Star Seal - FJ: flush joint connection for slim hole and horizontal wells. (Premium)

(a) Star Seal-Flush Joint (SS-FJ™) is a true-flush OD integral joint connection designed for moderate internal pressure applications where tension, compression or bending loads and annular clearance are significant concerns. SS-FJ™ is available in outside diameters from 4-1/2 through 8-5/8 inches in walls from .250 to .500 inches. Thread features are:

(b) Close-tolerance hooked threads virtually eliminate thread pullout.

(c) Rugged thread seal (5 threads per inch).

(d) Shallow stab flank angles to increase the connection’s compressive capacity.

(e) Connection inside diameter and pipe body are flush to provide a smooth transition area.

(f) Axial metal-to-metal seal.

(g) 15-degree radial torque shoulder to strictly control make-up position.

(h) Qualification testing for SS-FJ to Cal-II of ISO-36789 is underway. SS-FJ has been in production for over three (3) years and several million feet have been shipped and run successfully.

18.3 Star Seal – IJ: integral joint for combined loads. (Premium)

(a) Star Seal-Integral Joint (SS-IJ™) is a near-flush OD integral joint connection designed for moderate to high internal pressure applications where tension, compression or bending loads and annular clearance are significant concerns. SS-IJ™ is available in outside diameters from 4-1/2 through 8-5/8 inches in walls from .250 to .500 inches.

(b) SS-IJ™ takes advantage of the additional wall thickness made possible by forming the pipe end to increase tensile efficiency. Close-tolerance hooked threads virtually eliminate thread pullout.

(c) Rugged thread seal (5 threads per inch).

(d) Shallow stab flank angles to increase the connection’s compressive capacity.

(e) Connection inside diameter and pipe body are flush to provide a smooth transition area.

(f) Axial metal-to-metal seal.

(g) 15-degree radial torque shoulder to strictly control make-up position.

18.4 Star Seal-TC: Coupled connection for high-pressure high-temperature (HP-HT) wells. (Semi-Premium)

(a) Star Seal-TC (Threaded and Coupled) uses a near perfect buttress thread designed for wells where moderate to high internal pressure and high-tension loads are concerns. Star Seal-TC is available in outside diameters from 4-1/2 through 9-5/8 inches in walls from .250 to .500 inches.

(b) Joint strength is equal to API buttress, and burst rating is equal to 100 % of pipe body. Star Seal-TC takes advantage of its superior sealing ability made possible by the reduced clearances between threads and the use of tin coated couplings to make a virtually leak proof connection. Improved thread tolerances reduce thread-to-thread clearances. Thread features are:

(c) Rugged, field-proven buttress-type thread provides durability and high tension strength.

(d) Restricted, favorable tolerances ensure sealing at end of pin.

(e) Ductile plating on coupling to improve sealing, reduce torque and inhibit galling.

(f) Compatibility with API buttress threads and running equipment.

(g) Joint strengths and internal yield ratings equal those of the corresponding size and grade API Buttress connection.

(h) Coupling extension to stiffen and reduce hoop stress.

18.5 Star Seal –HW (Heavy Wall) for thick-wall high-pressure casing high-pressure high-temperature (HP-HT) wells. (Premium)

(a) SS-HW has been run successfully in strings to set to over 24,000 ft (7,300 m). SS-HW uses a near perfect buttress thread designed for wells where moderate to high internal pressure and high-tension loads are concerns. SS-HW is available in outside diameters from 5-1/2 through 14 inches in walls from .500 to .800 inches.

(b) Joint strength and burst rating are equal to 100 % of pipe body. Star Seal-HW takes advantage of its superior sealing ability made possible by the reduced clearances between threads and the use of tin coated couplings to make a virtually leak proof connection.

19. Other Important Lone Star Oilfield Product Application solutions developed from field work with customers and technical expertise and know how for several niche products include:

19.1 Subsea pipelines – A subset of pipelines for offshore use usually made to customer proprietary specifications instead of API standards.

19.2 Riser wear sleeves - Sacrificial wear resistant steel tube inserts to protect for offshore well drilling risers.

19.3 Drilling templates – Pipe for fabricated frames anchored to the seafloor to which an offshore platform may be attached.

19.4 Liner hanger tube - Tube from which to construct a mechanical device to anchor a “liner”. A liner is a casing string that does not extend to the top of the wellbore, but instead is anchored or suspended from inside the bottom of the previous casing string.

19.5 Sand screens tubes – Tubes upon which to assemble sand screens. Sand screens are a metal filter assemblies used to support and retain wellbore formation sand or the sand placed during gravel pack operations.

19.6 Jack-up leg chords – High-strength structural pipe for structural members for “jack-up rig” legs. A jack-up rig is a self-contained combination drilling rig and floating barge, fitted with long support legs that can be raised or lowered independently of each other.

19.7 Rig mast chord - Mild steel structural pipe for the main structural members for drilling rig “masts” – the structure used to support the crown blocks and the drillstring. A land rig mast must have very good stiffness, because it will be laid down when the rig is moved.

19.8 Rig mast lacing - Mild steel structural pipe for the structural members for drilling rig “masts” – the structure used to support the crown blocks and the drill string. A land rig mast must have very good stiffness, because it will be laid down when the rig is moved.

19.9 Blast joints – Thick-walled and/or carbide-covered tubes which are run with OCTG tubing strings opposite perforations in dual completions or directly below the tubing hanger in sand frac situations, to minimize the effect of external erosive action.

19.10 DH pump barrels – Tubes for downhole (DH) pump barrels. DH pumps are part of an artificial-lift system that uses electrically driven submersible centrifugal pump specifically configured to suit the production and wellbore characteristics of a given application.

19.11 DH pump parts - Tubes for downhole (DH) pump parts. DH pumps are part of an artificial-lift system that uses electrically driven submersible centrifugal pump specifically configured to suit the production and wellbore characteristics of a given application.

19.12 Mud pump parts - Tubes for parts for oil and gas well drilling fluid (mud) pumps.

19.13 Top drive components – Tubes for a topdrive, the device that turns the drillstring. Topdrives consist of one or more motors (electric or hydraulic) connected with appropriate gearing to a short section of pipe called a quill, that in turn may be screwed into a saver sub or the drillstring itself. The topdrive is suspended from the hook, so the rotary mechanism is free to travel up and down the derrick. This is radically different from the more conventional rotary table and kelly method of turning the drillstring because it enables drilling to be done with three joint stands

instead of single joints of pipe. Modern topdrives are a major improvement to drilling rig technology and are a large contributor to the ability to drill more difficult extended-reach wellbores.

19.14 Note that the above products described include tubes made the by the drawn over mandrel (DOM) process and pipe. Also, that MPM’s equipment limitations may exclude certain of these products.

20. Mechanical Tubing Products and Processes

20.1 Drawn Over Mandrel (DOM) production technologies.

(a) Cold Drawn Over Mandrel (DOM) - Tubing is pulled both through a die and over a mandrel to accurately and precisely size the tube’s OD, Wall and/or ID dimensions. Tubes produced by the DOM process results in closer tolerances, smoother surfaces, and greater strength. In addition to round tubes, shapes such as squares, hexagons, ovals, and rectangles can be produced.

(b) QDOM – Quenched and Tempered high-strength DOM tubing for applications that require very high strength and high toughness (CVN).

20.2 Pushbench and other methods of drawing small diameter tubing.

(a) A “pushbench”, for the purposes of Valin MPM, is a compact replicatable draw shop for the cold finishing short and medium length 10 ft (3m) tubes.

(b) The pushbench functions similar to a machining cell.

(c) Beyond general manufacturing pushbenchs may offer particular advantage for finishing automotive tubulars for suspension, transmission and steer applications and possibly door intrusion beams.

(d) DOM niche products include:

(e) Perforating Gun Tubes – Tubes for a device used to perforate oil and gas wells in preparation for production. The “guns” are shaped explosive charges mounted in the tube housing for easy deployment.

(f) Meter Run Tubes – Tubes with calibrated inside diameters to allow accurate flow rate measurement of liquid or gases into pipelines.

(g) Seal-Ring Gasket Tubes – Tubes used to make seal rings for process plant piping and to make metal-jacketed gaskets. Metal-jacketed gaskets, consist of a metallic outer shell with either a metallic or non-metallic asbestos free filler. The filler material gives the gasket resilience, while the metal jacket protects the filler and resists pressures, temperatures and corrosion. Metal-jacketed gaskets are used for heat exchangers, pumps and valves.

21. Fintube Technology

21.1 Finned tubes are used primarily for heat recovery steam generation in coal and natural gas fired power plants. Steel strip, with dimensions determined by plant

fuel are electric resistance welded to the OD surface of steel tubulars, effectively increasing their surface area relative to their volume, thus increasing heat conduction efficiency. Lone Star Technologies’ Fintube subsidiary is a recognized world leader in finning technology.

21.2 Fin design and fintube manufacture are covered by several patents licensed to the joint venture, among which are:

(a) Aerocurve Fin Segment, USA Pat No. 6,234,245.

(b) Process for Making Strip from Rod, USA Pat. No.5,638,714.

(c) Texturized Fin, USA Pat. No. 5,377,746.

21.3 Licensed Know How includes:

(a) Equipment specifications and operation.

Some Definitions

API American Petroleum Institute. A standardization organization composed of manufacturers, users and other interested parties. API publishes product standards for the oil and gas industry that are used worldwide. API standards are consensus standards. Consensus standards are those for which a consensus can be reached on solutions that meet both the requirements of business and the broader needs of society, such as the needs of stakeholder groups like consumers and users.

Burst The pressure at which pipe ruptures.

Internal Yield The pressure which generates at stress equal to the specified minimum yield strength (SMYS) of the steel on the inside diameter of the tube wall pipe or tube.

ISO “ISO” standards are published by the International Organization for Standardization (ISO). ISO is a network of the national standards institutes of 156 countries, operating on the basis of one member per country. A Central Secretariat in Geneva, Switzerland coordinates the system. ISO standards are consensus standards, and cover products and services beyond the oil and gas industry. “Iso” is Greek for “equal”. ISO is used the name for the organization, instead of International Organization for Standardization, to keep from having different abbreviations in different languages.

Pipe Tubulars that are finished products: Casing, Tubing, Line Pipe, Drill Pipe, Standard Pipe and Piling.

Non-API OD Pipe diameters not listed in the current Edition of API 5CT (Casing and Tubing).

OCTG Oil Country Tubular Goods: pipe used in the drilling and production of oil and gas wells - Casing, Tubing, Drill Pipe and Couplings.

OEM Original Equipment Manufacturers. OEMs are companies that build products, or components, which are used in products sold by another company.

Riser A large-diameter pipe that connects a subsea Blowout Preventer (BOP) stack to a floating surface rig to take drilling fluid returns to the surface.

Without the riser, the drilling fluid would simply spill out of the top of the stack onto the seafloor. The riser might be loosely considered a temporary extension of the wellbore to the surface.

SMYS Specified Minimum Yield Strength. Steel strength listed in a given standard used to calculate some performance properties for pipe or tubes, particularly in API and ISO standards.

Tube Tubulars that is used to make a finished product: Bushings, bearings, housings, cylinders etc.
