Dear Sirs,
I am doing review specification for high pressure vesels ((thicknes above 150mm), in the spec mention that the subsubsequce normalised is requiered after hot forming event the base plate already done normalised. I dont agree with that due to double normalised, it to be exspensive and...
Dear Gents,
could you pls advice
1. Do we need require separately stress relive after head hot forming of vessels
2. Which is best separately heat treatment require after hot forming
3. Is it necessary separately normolization after hot forming if base plate has been normolise.
Regards,
Johny
