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 PSL2.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.2, do PSL1 does not require impact performance, PSL2 all except x80 grade steel, full size 0 ℃ average Akv: longitudinal p j, 41 lateral acuity 27 j.Petroleum pipeline, natural gas, city pipe network, mine water slurry pipeline, high voltage transmission line, wind power, bridge.
