V351 Flange Adaptor is one of the most basic types of fittings. On one side, it has a flange connection in accordance with the required flange standard, on the other an insertion socket for the pipe. A variety of standard pipe types can be connected. Flange adaptors consist of one follower end ring, a middle ring and flange, one gasket and a set of bolts and nuts. Flange adaptors are ideal for joining a pipe to a flanged product like for instance a gate valve, butterfly valve, return flow inhibitors or fittings in gen- eral. Similar to a coupling, the compression chamber is formed by the follower end ring, middle ring and pipe surface. TVN flange adaptors can be equipped with flanges to any standard.
