The pressure bearing problem of 20 # seamless steel pipe has always been a detail issue for steel pipe practitioners. Although we can compare the pressure bearing capacity of seamless steel pipes using the 20 # seamless steel pipe pressure wall thickness comparison table, specifically for a certain seamless steel pipe, this issue is a bit tricky.
Because the pressure bearing capacity of 20 # seamless steel pipe is also affected by a series of issues such as temperature, internal fluid, and steel pipe production process in the working environment.
We can calculate the pressure bearing capacity of steel pipes by calculating fractions, with the formula: pressure=(wall thickness * 2 * tensile strength of steel pipe material)/(outer diameter * coefficient). Thick walled seamless steel pipes are mainly used for various purposes such as mechanical processing, coal mining, hydraulic steel, etc.
Taking an actual case with a DN of 10mm and a wall thickness of 3mm as an example, we selected 20 steel with a tensile strength of 410MPa and a safety factor of S=4, and calculated that the pressure that this pipe can withstand is 39.375MPa.
