Tolerance of Steel Pipe Thickness according to API 5L, ASTM A53 and EN10219

As different carbon steel pipe, both seamless pipes and welded pipes, will used for different application. Then for different usage, there will be many different steel pipe standards in the pipe fields. Thus there are different requirements. So, it's important to know what's your application before you inquire or purchase mild steel pipe.

Here we compare three steel pipe standard:

1.API 5L-This International Standard specifies requirements for the manufacture of two product specification levels(PSL 1 and PSL 2) of seamless and welded steel pipes for use in pipeline transportation systems in the petroleum and natural gas industries.
2.ASTM A53-This Standard is Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded steel pipe and Seamless pipe.Pipe ordered under this specification is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas, and air lines.
3.EN10219-This Standard is for Cold formed welded structural hollow sections of non-alloy and fine grain steels.
