API 6D - Drive train strength test


Hope you guys doing well!

Is drive train strength test is mandatory for API6D certification or valve validation??

Best regards

RE: API 6D - Drive train strength test

API 6D does not have a type test. However, auditor can ARGUE that you have to validate it through empirical testing.

The fact of the matter is it can be difficult (on larger size) to achieve torque values to break those stem.

Annex H
H.7 drive train strength test

RE: API 6D - Drive train strength test

i should correct myself. api does not have a mandatory type test. but yes, it's an optional test. again, very difficult to actually achieve on larger valves.
