Standards for copper flat gaskets
Thread Content
Is there any standard for the use of copper flat gaskets in chemical process piping, and are there any guidelines regarding their relationship with the corresponding pressure rating, pipe diameter, and thickness?
Please be more specific with your question; there aren’t many locations where copper gaskets can be used
Appendix B of HG20583 specifies that red copper gaskets shall be used for 6.4 MPa steam flanges.
I see that a lot of steam under such pressure uses octagonal gaskets, and the flanges are also of the RTJ type
I checked; there’s only a brief sentence, with no specifics given
CLASS600 DN200 welded flange with neck. What specification of copper gasket should be used?
The type of sealing surface determines the type of gasket used; there is a significant difference between RF and RJ – one starts at 4.5 mm, while the other starts at 16 mm
