KVA Stainless Introduces New Technology to Produce High Toughness Seam-Welded Pipe for Gas and Oil Production/Pipelines

Online, August 26, 2010 (Newswire.com) - KVA Martensitic Stainless Steel (MSS) tube and pipe are low-cost, high performance substitutes for traditional carbon steel, 12Cr and 13Cr materials. Douglas Gore, VP Sales is excited to let the world know about this new technology. KVA MSS is the patented, original and only fully martensitic, high toughness seam-welded pipe, offering unsurpassed tensile strength, hardness and wear resistance as compared to common low carbon corrosion resistant modifications such as:

Duracorr®
Cromgard®
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"), Submerged Arc Welding (SAW), Electric Resistance Welding (ERW) and Laser/Hybrid Laser-Assist Welding.
