Pressure Rating of PN25 Spiral Wound Gasket Built to EN 1514-2

[Pavan Kumar]

Hi All,

I want to determine the pressure rating of a PN 25 spiral wound gasket built to EN-1514-2. The gasket is 3 mm thick with X5CrNi18 Stainless Steel Inner ring, outer ring with flexible graphite filler. I have never checked gasket ratings before and some elaborate guidance.

Thanks and Regards,
Pavan Kumar

Errr 25 bar?

That's what PN 25 means.

Doesn't the gasket pressure and temperature rating depend on the Gasket material and thickness?. The gasket spec is mentioned in our pipe spec for suitable for PN25 flanges. Does this mean it has the same rating of PN 25 flanges ( EN 1.0460) at 205 Deg C, which is 19 bar(g).

Thanks and Regards,
