Metal wound gasket for pipe flanges
Thread Content
I would like to ask my friends: for DN50, PN16, with an RF sealing surface, how should the metal wound gasket be specified?
Refer to the standard \"GB/T 4622.1-2009 Coiled Gaskets – Classification\"
According to pipeline specifications, different industries use different ways of expressing these values. In the power industry, PN16 has always meant 16 megapascals, which is really annoying
It depends on what standards you are following For ordinary containers, in accordance with HG/T20610-2009 \"Wound gaskets for steel pipe flanges\", with an RF sealing surface, type D is generally selected
Different standards have varying labeling requirements; please check the specific labeling rules for each standard.
The standard most commonly used for pipe flanges is HG/T 20592; this standard also includes corresponding American and European standards, with flanges and gaskets that match accordingly.

It depends on the medium used; with a question like this, it’s not possible to give you a specific answer. For example, when water is used as the medium, D1221 is used
It depends on the material of the gasket you choose. Then label it according to the codes in the standard
