초록

A seal load ring having parallel radial faces is installed between the flared gasket portion of the piping plastic liner and the lapped end of a section of metal piping. The plastic engaging face of the ring is provided with a plurality of concentric circular grooves to resist plastic cold flow. The pipe lap has a significantly lesser outside diameter than the outside diameter of the seal load ring, only sufficient to support the joint connecting forces, thereby permitting easier and more economical fabrication of the pipe lap and permitting the use of l...
