介绍API X42和X52管道的差异
API 5L X42线管道API 5L X52. line pipe (Seamless and welded pipe) of all grades have PSL1 and PSL2 two product specifications, they are different on chemical composition, manufacturing processes, mechanical strength, heat treatment, test records, traceability etc. Actually, X42 and X52 etc. denote the minimum yield strength of the pipe steel. X42 has the minimum yield strength of 42 kilopound/square inch and X52 has the 52 ksi.
