Gentleman,
If I may ask how is PWHT accomplished in this case, is it with a furnace, induction heating or with a gas torch?
Many thanks

Hi sadique,
Designer has to specify pwht requirements.For example CS in amine service required PWHT irrespective of thickness.Even support welding required pwht.
It depends upon how material will react to service condition.On Sat, Jul 4, 2009 at 5:47 PM, Sadique Sheikh <sadiq.mech@gmail.com> wrote:
