Questions about PTFE/non-ASB material

Thread Content

FLAT GASKET Type FF CL150(PN2.0) PTFE/non-ASB sheet ASME B16.21(for ASME B16.5) 3 mm Is it correct to describe this gasket as a flat gasket? What is PTFE/non-ASB material? It would be best to have pictures to take a look at; please help answer this question. Thank you, experts!

This post was last edited by wangshunyu on 2018-2-28 at 10:08. PTFE/non-ASB polytetrafluoroethylene/non-asbestos gaskets, PN20bar; they are not flat gaskets but rather gaskets for FF flat flanges.

The description provided earlier indeed refers to flat gaskets; as for the material, the design institute’s response was PTFE without asbestos.

Why isn’t the diameter of this gasket specified?

Did the design office make a mistake? They intended to use non-asbestos PTFE material but didn’t remove it; there are specialized non-asbestos gaskets available! Do manufacturers add asbestos to polytetrafluoroethylene?

It’s written correctly; this is a PTFE reactive gasket, and the material used for the backing layer must not be asbestos.

Now, more and more enterprise design institutes are requiring the use of non-asbestos gaskets
