How to determine pipe wall thickness
Thread Content
I would like to ask everyone: When selecting the wall thickness of a pipe, is it still possible to use the method of calculating using Barlow’s formula, Sch=p/*1000, rounding the result to determine the appropriate pipe size, and then referring to table 20553 to find the corresponding wall thickness for that pipe size? What methods are commonly used by design institutes these days to determine pipe numbers and select pipe wall thickness?
SCH is not a specific wall thickness value, but rather a series such as SCH5, SCH10, SCH4, and so on. By referring to specific standards such as the petrochemical standard SHT345-2012, it is possible to find out the wall thickness corresponding to a given nominal diameter. This wall thickness also depends on the material of the steel pipe – whether it is stainless steel, seamless steel, or carbon steel
This is just a rough estimate; the choice needs to be made based on factors such as the toxicity of the medium. It’s also possible to carry out calculations according to standards, like @Yimi did – and there are calculation formulas available, so it’s not difficult
