20G —— this is the wall thickness chosen for this material
Thread Content
Does anyone know the method for selecting the wall thickness for 20G carbon steel? Is there a table that shows the wall thickness corresponding to different pressure levels, and where can I find it?
This should be calculated using a formula.
20G high-pressure boiler seamless tubes, material 20#, reference standard DG2000 for selection
20G generally refers to the 20# steel pipe specified in GB 5310. There is a limit on the operating temperature, which must be below 450°C. Pressure is unlimited. Under different pressure and temperature conditions, the wall thickness of steel pipes is determined by strength calculations. There is no wall thickness table corresponding to pressure grades.
