Help needed with pipe wall thickness selection! ! !
Thread Content
Design pressure: 1.1 MPa; Design temperature: 250°C. Pipe material: 316L seamless steel pipe. Standard: GB/T 14976. Outer diameter of the pipe: 114.3 mm for DN100 pipes, and 88.9 mm for DN80 pipes. Medium: As shown in the figure below; please ask an experienced expert to help calculate the wall thickness of the pipes under these conditions. Thank you!
Based on the conditions you provided, with a wall thickness class of Sch 20, it is recommended to choose a wall thickness of 5.0
As shown in the figure, for the calculation formula, refer to GB/T20801 for details
For ordinary pipes, Sch40S is recommended; the wall thickness is 6.02 for DN100 and 5.49 for DN80. As for pipes subject to conditions such as cyclic vibration, I won’t carry out any calculations either, haha.
