For pipeline selection, once the diameter and wall thickness are known, what should be done next?
Thread Content
The pipe diameter is known to be DN150; the initial calculation gives a wall thickness of 8.72, with no margin for safety and no rounding applied. How should the appropriate pipe material (carbon steel) be selected, and which standards should be followed?
Selection is made according to Table 1.6 \"Steel Pipe Wall Thicknesses\" on P4-6 of the third edition (Volume 2) of the \"Chemical Process Design Manual\". In the case of severe cyclic conditions or pipelines for Class A1 fluids, when stainless steel pipes and butt-welded fittings are used, the thickness shall not be less than that specified in Appendix D of GB50316 \"Code for Design of Industrial Metal Piping\".

You're right
Thank you. How is the material determined? It’s 25 MPa compressed air, with no corrosive agents present
So, what exactly do you plan to do? Has the standard system been established yet?
