DN 350: The gasket size indicates a nominal pipe diameter of 350 mm； PN2.0 gasket operating pressure: 2.0 MPa ； The material of the gasket 2525 is stainless steel; it is likely X5CrNiMoTi2525 stainless steel, a type of stainless steel that complies with German DIN standards ； ASME B16.20 Pipe Flanges – Ring Joint, Spiral-Wound and Covered Metal Gaskets.
This is an expert-level answer, very detailed.
Absolutely correct, so helpful and generous – a thumbs up for you! Here’s a little flower for you
There are many experts in Haichuan; feel free to communicate more if you have any questions
This 2525 doesn’t mean that, right? I think it means the following (numbers from left to right): 2: The material for the center ring is 304 ； 5: The metal strip is made of 316L ； 2: The filler is flexible graphite strips ； 5: The inner ring material is 316L.
I suggest you take a look at the relevant specifications and standards; they are very detailed
