Description

API 5L Grade X65 PSL1, PSL2, and sour service pipe differences

API 5L X65 PSL1

API 5L Grade X65 or L450 PSL1 pipe is normal carbon steel material among the tree types and for common use, (No corrosion environment but in high-pressure pipelines required certain mechanical properties). so it has the highest content of C, Mn, Si, P, S than the other two types. (These chemical elements is lower the steel is purer). X65 PSL1 pipe Minimum yield strength is 450 Mpa (65300 psi), and minimum tensile strength 535 Mpa (77600 psi).

API 5L X65 PSL2

For API 5L X65 PSL2 (API 5L X65Q.M or L450Q/M), C ≤ 0.18, Si ≤ 0.18, Mn ≤ 1.70, P ≤ 0.025, S ≤ 0.015, all of these elements have less value than PSL1. Since PSL2 requires CEq ≤ 0.43, and CEpcm ≤ 0.25. (Ceq is carbon equivalent, it affects the steel welding performance, and strength value). And because of this, API 5L X65 PSL2 pipe (welded and seamless) mechanical strength has maximum limits: yield strength 450 – 600 Mpa (65300 psi to 87000 psi), tensile strength 535 to 760 Mpa (77600 psi to 110200 psi)

API 5L X65 sour service

API 5L X65 PSL2 sour service pipe (X65QS/MS, L415QS/MS), C maximum is 0.10, Mn ≤ 1.45, Si ≤ 0.45, P ≤ 0.020, S ≤ 0.002, V ≤ 0.10, Nb ≤ 0.08, Ti ≤ 0.06, CEPcm ≤ 0.22. Sour service line pipe requires a strict control on the chemical composition. So to protect pipes from corrosive environments like H2S, low carbon and low CEPcm value will reduce the martensite which is sensitive to the H bubble, so to improve the corrosive resistance to H2S. Moreover, P and S also should be less than normal line pipes. Out of these, the mechanical strength is the same with API 5L X65 PSL2 steel line pipes.

According to the data, 74% of pipeline accidents were caused from pipe corrosion, and H2S is the mainly corrosion types in corrosive environments. So it is very important to manufacture steel line pipe for sour service. View API 5L Pipe Specification for more details.
