WELD RINGS

Weld rings are recommended for use in any place where a welded seal is necessary, due either to the danger of the medium or the danger presented by a loss of functionality, but where the connection also needs to be detachable to a certain degree.

These gaskets are therefore described as being semi-de­tachable, as the welded sealing joint needs to be undone as well as the flange bolts.

Weld ring gaskets are generally made of the same or a related material as the pipe or flange and are only used in pairs.
