Weld ring gaskets
We recommend weld ring gaskets 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.
The choice between the various profiles depends on the operating conditions of the weld ring gasket. The table shows the typical features of Profiles A21 to A25. The ”attachment seam“ is the connection of a welded half with the flange. The
”attachment seam“ can be located internally or externally. The ”seal seam“ is always the welding of both weld rings with one another.
