Hi,

Hi all,
I have a supplier that would like to evaluate to product all the internal threads (integral flanged connections, threads UNC or 8-UN type machined directly on the vessel) with cold forming instead of machining.
Do you know if there is any guideline provided by the ASME for the type of...
Thank you for your reply.
Here an update:

- Edstainless: thank you for your opinion, but this time 316 shall be used under water for 20+ years because service is hydrogen...
Hi all,
I have a doubt and I am really not expert in corrosion engineering so I am searching to gain some knowledge here.
I have a SS316 module designed to work subsea under cathodic protection. There is a valve installed in the module with an internal mechanism, also made in SS316L. The...
Does the ASME address anyhow the loosening failure risk of bolted joints under vibration?
I do not find anything written in the entire ASME collection.
Thanks!!!
