MOLD AND METHOD FOR FORMING ELASTOMERIC FLANGE LININGS FOR PIPES

摘要

An elastomeric flange lining is provided for the metal flange of a pipe, the flange lining being structured with an annular channel with allows lateral movement of the elastomeric material of the flange lining when the flange li ning is subjected to high compression forces, such as when two pipes are joined toge therend-to-end at their respective pipe flanges. The des ign of the flange lining andmanner in which the flange lining is produced pr events outward bulging of elastomeric material into the interior of the pipe when subjected to compres sionforces. A flange mold for forming the flange lining is disclosed, and the methodof making the flange lining is also disclosed.
