Pressure/Temperature ratings of PN64 flanges

Pressure/Temperature ratings of PN64 flanges

Pressure/Temperature ratings of PN64 flanges

I need to determine the ratings for PN64 flanges in 316L stainless.

So far I've found a german copy of DIN2636 consisting of just a drawing and a page of dimensions, am I missing something?

My copies of BS4504 and ISO7005 don't include PN64.

Any suggestions where else to look?

RE: Pressure/Temperature ratings of PN64 flanges

Hello Andrew,

ANSI          ISO
150           20
300           30
400           64
600           100
900           150
1500          250
2500          400/420

RE: Pressure/Temperature ratings of PN64 flanges

Hi Andrew,
You may refer to the following standard for the pressure temperature ratings of PN64 flange in SS316L material.
prEN 1092-1.

Checkout also thread Thread292-17262

Especially Fawkes answer from april 10 gives some useful info about the difference between ISO 7005 and EN1092 - also with respect to pressure ratings.
