Pipeline wall thickness calculation standards
Thread Content
Hello everyone. There are many standards that provide formulas for calculating pipe wall thickness, but the formulas and constraints specified in different standards vary to some extent. There are also differences between domestic standards and foreign standards such as ASME； Some domestic standards specify that the ratio of outer diameter to inner diameter must not exceed 1.7; however, the ASME standard does not impose such a restriction. I wonder which standard people usually use to calculate wall thickness? ? ? ? Which standard should be used for thick-walled pipes (outer diameter/inner diameter ≤ 1.7)?
On my end, it’s as follows: test pressure (design pressure x 1.5) = 210 x wall thickness / outer diameter of the steel pipe; calculations are generally done using this value
