Im working on Boiler Construction Project - piping section and this is my first experienced in construction.
I have encountered a piping and a valve that dont
have same thickness....valve thickness is 19mm over and my
pipe is quite lower. So im considering the PWHT.please advise if you have a basis on this kind of situation.
thanks in advance.
