Description:
United States pressure pipe commonly used materials
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
Applications:
Used in industries as chemical engineering, petroleum, medicine, food, energy, nuclear power, aerospace,
environmental protection, boiler, gas, war industry, machinery, ship building and so on.
Competitive Advantage:
