Re: [MW:26860] SR equirement for Heads

Hi Friend

PWHT of D/End after forming depends upon various factor and accordingly to be decided

i) Fiber elongation occurred during forming (Generally above 5% needs PWHT)

ii)Service condition i.e. Sour service required PWHT

iii) Clients spec Some of the spec allows SR and some insists for Normalising

 Accordingly  you have to decide

Dear Experts,

AS per IL spec.all cold formed heads need to be stress relieved.
