Regarding the pressure resistance of stainless steel pipes
Thread Content
I would like to ask the experts: I often come into contact with various pipes these days, but I have only a superficial understanding of the pressure-bearing capacity of pipes with different wall thicknesses. For example, for a pipe with an inner diameter of 76 and a wall thickness of 3 mm, what is the maximum pressure it can withstand? Are there any tables or formulas I can refer to? Please advise.
Using the wall thickness calculation formula specified in GB/T20801, it is also necessary to know the corrosion allowance of the steel pipe, the design temperature, the design pressure, as well as the specific stainless steel material
It cannot be downloaded on Baidu; does anyone have these materials?
Search on this forum and you’ll find shared formulas for calculating thickness. . .
Check the relationship between pipe wall thickness and pressure rating
Check the manual: there are specifications regarding pipe wall thickness and pressure rating; following those specifications ensures correctness. Additionally, you can also use calculation. The value obtained from general calculations, plus a corrosion allowance, is generally sufficient. Our valves are pressure fittings, and there are corresponding standards that specify the wall thickness of such valves ； Tubes are forgings, usually heat-treated, and therefore possess better strength and mechanical properties compared to castings ；
