What is pressure rating of 3 xxxh smls pipe?

Answer 1

The pressure rating of a 3-inch schedule 40 seamless (smls) pipe typically depends on the material used, such as carbon steel or stainless steel, and the temperature of the fluid being transported. For example, a carbon steel pipe may have a pressure rating of approximately 300 psi at room temperature. However, it's essential to consult specific piping codes and standards (like ASME B31.3) for accurate ratings based on the intended application and operating conditions. Always verify with manufacturer data for precise specifications.
