A 10 year old reactor, the jacket of the reactor has not been used for 3 years. Client wants to re-connect the jacket with steam ( 8 barg saturated). Jacket design condition is 10 barg 250 C stainless steel.
We suggest to do inspection before let steam going through. Client doesn't think it necessary is. There is an inspection report from 4 years ago, but it is only about the reactor not jacket.
Is there a regulation or standard explaining this issue?
Any advices?
Thanks in advance.
