Forum Technical Discussions Gamma Plug Installation Posted by: Keith MacLean , E-mail: Address, on May 09, 2008 at 21:22 : What is the code intent for Post Weld Heat Treatment of a P5 Gamma plug in a B31.1 pipe. On boilers, a 3\8" seal weld is allowed without Post Weld Heat Treatment. But the rule for P5 material in B31.1 is confusing. Any preference on dye or Mag. after the weld is done Follow Ups: Re: Gamma Plug Installation ezekiel 14:48 May-12-2008 (0) Post a Followup: Name: E-Mail: Subject: Comments: ----------- Start Original Message ----------- : What is the code intent for Post Weld Heat Treatment of a P5 Gamma plug in a B31.1 pipe. : On boilers, a 3\8" seal weld is allowed without Post Weld Heat Treatment.
