?
Pipe under A312 standard also need to do Hydrostic test, annealing.
thickness tolerance: +-12.5%
others HRB<90
?
Generally speaking, the diameter of the pipe can be divided into outer diameter, inner diameter, nominal diameter.
The outer diameter of the tube for the seamless steel tube D To express,
Subsequently the size and wall thickness of the outer diameter,
For example
Size 108 Seamless steel pipe, wall thickness 5MM
Use. D108*5 Express
