JOINT FOR PLASTIC LINED LIGHT-WEIGHT METAL PIPING

摘要

A seal load ring having a radial face and a tapered face is installed between the flared gasket portion of the piping plastic liner and the frusto-conically flared flange end of a section of light-weight metal piping. The radial face of the ring is provided with a plurality of concentric circular grooves to resist plastic cold flow, and the connection is effected by a split V-clamp.
