Follow on Google News | KVA Stainless Introduces New Technology to Produce High Toughness Seam-Welded Pipe for Gas & OilPatent Technology Creates a New Market for Low Cost, High Strength Stainless Steel Pipes for Gas and Oil Production
By: Douglas Gore Duracorr® (UNS S41003) Cromgard® (UNS S41003) 3Cr12 410S (UNS S41008) 409 (UNS S40920) 12Cr 13Cr KVA Martensitic Stainless Steel pipes can be produced in standard sizes up to 36” and wall thicknesses up to 0.500”. Non-standard sizes upon request. KVA longitudinal seam-welded MSS can be produced fully hardened, fully annealed, or anywhere in between, at substantial cost savings over seamless 410 or 420 pipe! Typical properties of KVA MSS pipe: Hardened: Yield strength: 160 ksi (1100 MPa) Ultimate tensile strength: 205 ksi (1400 MPa) Hardness: 370-390 Brinell (40-42C Rockwell ) Elongation: 8-9% Annealed: Yield strength: 45 ksi (300 MPa) Ultimate tensile strength: 80 ksi (530 MPa) Hardness: 130 Brinell (80B Rockwell ) Elongation: 30+% The introduction of KVA Martensitic Stainless Steel for the transport, oil and gas pipelines is ideally suited for mildly corrosive, abrasive media applications such as: Oil sands Slurry pipelines Coal transport The abrasion resistance of hardened KVA MSS tube and pipe is unmatched – maximizing durability, reliability and reducing erosion-corrosion failures. KVA Martensitic Stainless Tubing can be produced with chromium content ranging from 11.5wt% to 16wt%, maximizing production and service life while minimizing cost. KVA MSS can be produced to the following specifications: ASTM A268: Standard Specification for Seamless and Welded Ferritic and Martensitic Stainless Steel Tubing for General Service ASTM A999: Standard Specification for General Requirements for Alloy and Stainless Steel Pipe API-5LC: Specification for CRA Line Pipe Please contact us to discuss your particular application with KVA. KVA can recommend the appropriate welding procedure for field welding MSS without cracking or embrittlement for welding methods such as: Gas Tungsten Arc Welding (GTAW/TIG), Gas Metal Arc Welding (GMAW/MIG), Shielded Metal Arc Welding (SMAW/”stick”) Douglas Gore KVA Stainless 124 S. Market Place Escondido, Ca 92029 http:www.kvastainless.com # # # Located in southern California, KVA Stainless is a growing R&D venture focused on developing and promoting uses for lightweight, ultra high-strength, low cost alloys. KVA Stainless' technical staff, with a combined 60 years experience in thermal processing, metallurgy, automated welding, brazing and mechanical design, have developed numerous proprietary and patent-pending processing and manufacturing methods to enable the use of lightweight, corrosion-resistant, hardened stainless steel components throughout industry. KVA Stainless' president, Mr. Ed McCrink, founded Hi-Temp, Inc. in 1953 and grew the company to become one of the largest processors of martensitic stainless steels in North America. Since successfully selling the Hi-Temp, Inc. plants in the 1970’s, he has continuously pursued his vision of utilizing commonly available martensitic stainless steels to reduce weight and increase strength in structures.
