May be we can find there is only one word difference between API 5L PSL1 X52 and API 5L PSL2 X52, the content of these two standards is very different. All said the same piece, but the requirements are very different. Katalor will elaborate on the difference between API 5L PSL1 X52 and API 5L PSL2 X52:
1.PSL is the abbreviation of product specification level. Line pipe product specification levels are divided into API 5L PSL1 X52 and API 5L PSL2 X52. These two specification levels are not only different from the inspection requirements, but also have different chemical composition and mechanical properties. Therefore, when ordering according to API 5L PSL, the terms in the contract are not specified except for the common specifications such as specification and steel grade. , must also indicate the product specification level, namely API 5L PSL1 X52 or API 5L PSL2 X52. API 5L PSL2 X52 is stricter than API 5L PSL1 X52 in terms of chemical composition, tensile properties, impact energy, and non-destructive testing.
2.API 5L PSL1 X52 does not require impact performance, all grades of API 5L PSL2 X52 except x80, full size 0°C Akv average: longitudinal ≥ 41J, transverse ≥ 27J. X80 steel grade, full size 0°C Akv average: longitudinal ≥101J, transverse ≥68J.
3.The line pipe should be tested hydraulically on a branch-by-branch basis, and the standard does not stipulate that the non-defective substitute water pressure is allowed. This is also a big difference between the API standard and the Chinese standard. API 5L PSL1 X52 does not require non-destructive testing. API 5L PSL2 X52 should be tested on a non-destructive basis.
