I’m passing by, expert – how do I read this chart? Thanks for the guidance.
The φ14 T-tube is welded by butt joint, so why is the φ18 tube welded by socket joint? Please ask an expert for guidance. Thank you
For example: with an outer diameter of 12 mm and a wall thickness of 1.0 mm, the maximum pressure resistance at room temperature is 20.2 MPa.
HG 20512 is not explained in detail here; only the conclusion is provided. There is a mathematical relationship among the pipe wall thickness, inner diameter, and pressure rating; the calculation methods can be found in Section 2 of ASME B31.1 or Section 2 of ASME B31.3. The calculation results for metric pipelines can be directly referenced using the DL 5190 standard.
