Questions about the heat treatment of alloy pipelines?
Thread Content
During normal construction, it is difficult to perform heat treatment on alloy pipelines with a diameter of DN50 or less. Does this approach affect their daily use?
I don’t think I had noticed this issue before; I’ll pay attention to what everyone says.
Pipes with a diameter of DN50 or less can still be processed; there are smaller heating strips available. In our projects, heat treatment is applied to all the branch pipes connected to the main steam pipes. If that really doesn’t work, it’s fine to wrap a heating wire (heating cord) around it as well. It is best to subject all high-heat-stress alloy pipes to heat treatment
