API 6 A Valve. Body Machined from Forged Cylinder/Forged Cube?
API 6 A Valve. Body Machined from Forged Cylinder/Forged Cube?
(OP)
Hello All
Is it permissible (or is it prohibited) to Machine a 9" Valve (Flanged) body from a Forged Cylinder of 500mm dia and 200 mm high or a forged cube of 450mm side?
Is it mandatory to forge the component as close as possible to final shape or is it permitted to machine the part from a forged cube or forged cylinder.
If there is a prohibition, request you to provide me the reference clause of API 6 A.
Material under discussion is AISI 4130.
PSL 2.

What is the purpose of using a forging if the advantage of grain structure control is wasted?

1. You know you have a heavy-wall chunk of metal with good integrity
2. You don't have to invest in a pattern.
3. You don't have to wait on a foundry cycle.
