How to select the nominal wall thickness, and how to choose the wall thickness for the SCH series.
Thread Content
What is the nominal wall thickness in mm for a carbon steel pipe with a diameter of DN250 and a design pressure of 19 MPa? How is this value determined? The SCH series has ten grades – how should I choose the appropriate wall thickness? Can the nominal wall thickness be determined solely based on the pipeline dimensions and pressure? ）
Can someone tell me where the calculation formula is?
Please refer to the pipeline design specifications, as they contain the specific requirements. Calculate everything step by step in strict accordance with the specifications; do not rely on hearsay
The pipeline medium is still needed, right?
