1. Grades covered by this specification are A25 ,A ,B (and the following "X" Grades), X42, X46, X52, X56, X60, X65, X70, X80.  The two digit number following the "X" indicates the Minimum Yield Strength (in 000's psi) of pipe produced to this grade.

API 5L PSL2 NACE MR 0175 seamless line Pipe is one of our most professional products. The production capacity is 100 thousand tons annually. It is sold well at home and abroad. SMLS is short for seamless steel pipe.

Seamless steel pipe for sour service according to NACE MR 0175It is especially used for the environment of sour service. to anti the corrosion of H2S.API 5L PSL2 NACE MR 0175 SMLS is used to resist acid when transporting liquid, oil, gas, etc. The hardness is less than 22HRD.
