Re: [MW:4155] ASME SEC IX...PWHT?

Hi Nandesh,                     For PWHT requirement detail is not given in ASME Sec IX, it is required based on construction code and Client specification.   As per ASME B31.3 , generally PWHT  required  for A333 Gr.6 is above 20 mm thk, but based on service fluid it will be higher requirement than code.   In my previous shell project some services requirement is 100%.   Louis Singapore     --- On Tue, 26/1/10, Nandesh Kumar <nandeshkumar@rocketmail.com> wrote: From: Nandesh Kumar <nandeshkumar@rocketmail.com> Subject: [MW:4150] ASME SEC IX...PWHT?
