Scope
JB/T 90-2015 is the English-translated version of 管路法兰用缠绕式垫片.
JB/T 90-2015 is a recommended Chinese machinery industry standard for the spiral wound gaskets used on pipe flanges. The standard establishes the types of these gaskets and their dimensions.
The gaskets in its scope are those fitted to pipe flanges, and the text confines the application to a band of nominal pressure classes. Its subject matter is dimensional and typological: what the document settles is which shapes and sizes of wound gasket are standard for a flanged pipe joint.
Among the standards it quotes are GB/T 4622.1 and GB/T 4622.3. JB/T 90-2015 replaces JB/T 90-1994. In the Chinese classification of standards the document carries the code J15, and in the international classification it carries 23.040.60.
