Shaanxi World Iron & Steel Co.,Ltd | Updated: May 31, 2018

What’s the difference between API X42 and X52 pipe?

 

Grades covered by API 5L standards are A25 ,A ,B and "X" Grades such as X42, X46, X52, X56, X60, X65, X70, X80 ans so on). The two digit number following the "X" indicates the Minimum Yield Strength (in 000's psi) of pipe produced to this grade.

Here I will show you the comparison between X42 and X52.

 

API 5L X42 line pipe and 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.
