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 and so on. the two-digit number following the "x" indicates the minimum yield strength (in 000's psi) of pipe produced to this grade. some people really confused about the x42 and x52, today here i will show you the comparison between them.

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. the steel pipe grade x42  has the minimum yield strength of 42 kilopound/square inch and x52 has 52,000 ksi.
