Pipe wall thickness
Thread Content
I would like to ask fellow sailors: is the pipe wall thickness calculated or chosen? Is the wall thickness of a pipe determined once its material and pressure rating are fixed?
You are correct in your understanding; once the pipe grade for a pipeline is determined, its wall thickness is generally also determined, as the pipe grade includes information on pressure, temperature, pipe size, and material wall thickness. However, when determining the pipe grade, this wall thickness is determined through calculation.
Of course, it needs to be calculated first: https://bbs.hcbbs.com/thread-2981135-1-1.html
For small-diameter medium and low-pressure pipes, the wall thickness can be found directly in the manual without any calculations required.
Calculate first, then select from the standard wall thickness table! The calculated values are generally very small, and the selected wall thickness makes procurement easier
