BPVC gasket materials

BPVC gasket materials

(OP)
I have a solid copper wire (.080 cross section) and used as a static face seal inside a groove on a flange. I am wondering what the seating stress is. According to ASME Section VIII BPVC on table 3-320 they list a ring joint gasket with a seating stress of 18,000 for iron or soft steel. Should I use this value.   

RE: BPVC gasket materials


The seating stress for soft copper is provided for a Solid Flat metal gasket as 13,000 psi. ND The soft iron properties are the same for Sold Flat and Ring Joint. I have used the subject value in your application with success.

If you have further concern www.lamons.com has excellant Tech Support.
