Who could tell me the minimum temperature admissible for ASTM A217 gr CA15. It seems that it is a equivalent to 410 but I am not sure.
Thanks to help me.
Who knows the main difference bteween these 2 standards ? Somebody told me that with API6D the check valves (flanged) can not be installed in vertical position but I don't see that in the API standard.
Thank you.
Hi,
One of our customer ask us ball valves for cryogenic service according to BS 6364 and he mentionned that valves must have a cavity provision relief.
Does anybody know what it is because manufacturer doesn't know.
Tahnk you for your help
