Sch40 P91 Pipe Welding Procedure

Welding Sch40 P91 Pipe generally requires preheating the joint, maintaining interpass temperatures, hydrogen bakes, and postweld heat treatment (PWHT). Preheating, typically to 400 to 500 degrees F, drives off moisture and thereby reduces hydrogen.

Sch40 P91 Pipe Failure In China

As per an incident of Pipe Failure in China in Dec 2006, you can see at the second picture there is no evidence of any ductility in this material. This was supposed to be seamless Grade 91 pipe material. This could imply there was either a seam weld (preferred path of failure) at this location or a pre-existing flaw (hard to tell from the photo) from fabrication.
