Re: [MW:26567] ASME B31.3 -2014 Table 331.1.1 Soaking time for P1 material

Dear,
For your information the latest edition ASME B31.3 says there is no any requirements of PWHT.
If the wall thickness is more then will do preheat @95 Deg Celsius and which exemption of PWHT.

Hi Team,

Could any please clarify

What is the minimum required soaking time for P1 material with wall thick 12mm, as per ASME B31.3 year 2014 Table 331.1.1 .

Is it still Minimum one hour per 1 Inch wall thickness or Minimum 15 Minutes...
