The Saufrex material generally has a good life and the corrosion rate is very low. You might want to check the previous history of the HP loop and the corrosion rate pertained to these equipments before making the call inspection frequency.
If you had it inspected by Stamicarbon inspection team...
Can a CF8M (SS-316) cast valve disc be magnetic by any means.
I was a little shocked to see austenitic SS magnetic

I wish to ask if passing of PSV (Pressure safety valve) can be identified by acoustic emission technique and if yes, can it be done while the stream is online. Does any of you have such an experience?
Thanks Duwe6,
Good to see a reaction on this post. but from what i understand from your post. there is no set rules from any of the standards ASTM or API for the PSV set pressure for such cases. and interestingly 1.33 x hydro pressure was also practiced, which makes the case that upto 33% was...
Hello Everyone,
I am a mechanical engineer.
I just wanted to know if there was any set pressure requirements while testing an equipment.
For Ex. Suppose we are hydro testing an Exchanger or vessel. we install a PSV on the test circuit. what should the set pressure of the PSV be? is there any...
