Abstract
A pipe for lining a passage includes at least a first pipe section having a bell at one end and at least a second pipe section having a spigot at one end, adapted to mate with the bell of the first pipe section. The pipe sections are closed molded to form the final geometry of the bell and spigot. At least one of the bell of the first pipe section or the spigot of the second pipe section has a circumferential groove molded therein to substantially its final shape. An elastomeric gasket sized to fit in the groove forms a compression seal between the first pipe section and the second pipe section.
