The issue of the height of the flange sealing surface

2009-02-27View Original

Thread Content

Could everyone please advise me on the requirements regarding the height standard of the flange sealing surface? For example, how high is the sealing surface of a 3\" CL300 flange?

It depends on what standard your flange is. Standard flange documents generally contain detailed specifications regarding dimensions, including inner and outer diameters, bolt hole diameters, diameter of the hole centers, and thickness, among others.

Raised Face (RF), with a height of 0.06\" or 1.6 mm; this is in accordance with ASME B16.5 standards. I hope this clarifies your question.
