Is there a specified minimum wall thickness for pressure pipes?
It depends on the pressure rating, pipe diameter, and wall thickness, as there are requirements for these
Of course, for Series A, it is recommended to refer to SH3405-2012; for Series B, it’s more complicated – use HGT 20553-2011. This standard provides a series of specifications for seamless and welded steel pipes used in chemical piping, and one should select the appropriate model based on the required pressure level
I’m talking about something that is independent of the pipe diameter; no matter what the diameter is, the wall thickness must not be lower than a certain value. Just like the requirement that the wall thickness of carbon steel and low-alloy steel in pressure vessels should be no less than 3 millimeters, are there any similar requirements for pressure pipelines?
Specification SH/T 3059-2012 \"Code for Selection of Materials for Petrochemical Piping Design\" contains a provision as follows:
This is the result I need, but general standards like 20801 or 50316 don’t seem to include such information
I’m also looking for the regulations on this, but I haven’t found them yet!
Different pressures require different wall thicknesses, and there are **relevant standard specifications for this. I have the standards for pipe fittings here and am happy to share them free of charge.
Such standards are not something ordinary people would dare to use; those of us in the design field need to take many factors into consideration. Dedicated wall thickness standards are more reliable and offer greater accuracy. They are all verified empirical data values! ! ! :)
The minimum wall thickness of the gas pipeline shall be 4.5 mm, and the ratio of the outer diameter to the wall thickness shall not exceed 100
