DN1420 mm Tensile Strength Elongation 24 Inch Steel Pipe 3LPE Coating

Tensile Strength, Yield Strength, Elongation 24" Inch Diameter LSAW Steel Pipe

American API 5L pipeline steel pipe implementation standard.Production material: Q195A-Q345E;245 r;Q345QA - D;L245 - L485;X42 - X70.The main bearing parameters are 2ST/T, S is the yield strength, T is the wall thickness.Submerged arc welding has been developed into double - wire submerged arc welding, and multi - wire submerged arc welding, further improve the efficiency.Widely used in steel structure, pile driving, fluid conveying, long - distance pipeline and other places.

Straight seam submerged arc welding pipe production cost is high than high-frequency steel pipe, spiral steel pipe, but compared with seamless pipe price space is very large.High frequency straight seam submerged arc welding pipe can produce the material of steel pipe and spiral steel pipe can't production, such as high-frequency steel pipe is usually in domestic commonly used specifications, and batch production inventory, usually made of Q235B, Q345B, high frequency equipment and other hard steel material spiral equipment domestic can't production.

Straight seam submerged arc welding pipe in domestic heavy steel structure engineering and fluid pipeline engineering, wide application in the foundation pile engineering.Petroleum pipeline, natural gas, city pipe network, mine water slurry pipeline, high voltage transmission line, wind power, bridge.

1. PSL is short for product specification level.Line pipe product specification level is divided into PSL1 and PSL2, also can say quality grades are divided into PSL1 and PSL.

2. PSL2 above PSL1, these two levels is not only different inspection requirements, and chemical composition, mechanical performance requirements are different, so the order in API 5 l, the terms of the contract in addition to indicate the specifications and grade of steel usually indicators, must also indicate the level of product specification, namely PSL1 or PSL2.PSL2 in chemical composition, tensile properties, impact energy, and nondestructive testing which strict in PSL1 indicators.
