Dear All,
As the title suggests, I want to use SAW process instead of EFW process for fabrication of 2000 NB pipes. The design pressure is 1.01 bar (g) and the design temperature is 80 degrees centigrade.
Class 1 will be used (100% RT).
Can this substitution of welding process be made? I...
Is that up to the seller or the buyer is they want heat treatment or not? The pipe is specified as EFW Ej =1 Pipe DN 2000, A312 TP304.
If the spec is EFW, A312 should not be possible right?
Descaling and annealing is not a problem. My company fabricates pressure vessels for which we do...
Can a 2000 NB pipe be solution annealed? I'm from India and nobody in the country is able to do it. If you are sure it can be done, please confirm, will look for some exporters.
I need to fabricate a pipe of DN 2000, wall thickness of 14.3 mm, from SS304 plate. Applicable code is ASTM A358 (please confirm). The standard says the following regarding heat treatment:
The problem here is two-fold:
1. The plates are sold by steel mills with solution annealing already - is...
