Seamless steel pipe schedule 40
SCH40, tube number, whether it is domestic or foreign, Sch.XX is used to indicate the wall thickness of the pipe. GB/T81631 HG20553 is also included in the national standard GB/T81631 HG20553, etc., according to the outer diameter of the pipe or the pipe size, the wall thickness of different sizes indicated by the same pipe number are different.
Pipe wall thickness grade Sch40, carbon steel, low alloy steel of a thickness class code, corresponding to a certain pipe thickness.
Sch40: indicates tensile strength, 40 kg pressure. It can be detected through standard thickness of 4.0mm. Tubes of different diameter, different pressures, different wall thickness.
