Piping Engineer Interview Mumbai

There is a power plant inside a Process refinery. Where

  exactly the ANSI B31.1 & ANSI B31.3 scope break occurs?

Interview Answer

1 Answer


Based on my experience there were two cases. Case #1, B31.1 stopped at the Power Plant Unit block valves. Thus all piping inside the Power Plant was B31.1. Case #2, B31.1 stopped at the equipment (Boiler) isolation block valves and then all other piping was B31.3. This is normally the choice of the owner/operator/client.
