Abstract

A force-transmitting joint formed between two pipe sections is provided that is particularly suited for an extruded, plastic pipe having a variable wall thickness. The joint has a smooth outer surface and a constant gap in which a sealing member is retained. The pipe section has an outer wall including an outer surface and an inner surface with a variable wall thickness defined therebetween. A first end of the pipe section includes a first joint member comprising a first support surface having a constant width. The first joint member further comprises an outwardly extending sealing leg having a variable width. A
second end of the pipe includes a second joint member comprising a second support surface having a constant width which is less than the width of the first support surface. The second joint member further comprises a recess having a variable thickness.
An annular sealing member is assembled onto the sealing leg.
When the first joint member of one pipe section is joined to the second joint member of another pipe section, the first support wall and second support wall align in a force-transmitting relationship, the sealing leg is at least partially received in the recess and a constant-width gap is formed between a wall of the recess and the sealing leg. The sealing member is retained in the constant-width gap.
