ABSTRACT:
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 lining is subjected to high compression forces, such as when two pipes are joined together end-to-end at their respective pipe flanges. The design of the flange lining and manner in which the flange lining is produced prevents outward bulging of elastomeric material into the interior of the pipe when subjected to compression forces. A flange mold for forming the flange lining is disclosed, and the method of making the flange lining is also disclosed.
