Rigid corrugated plastic pipe sections are provided with a flange radially extending from at least one end of the pipe length, which allows structural and water tight joints between connecting flanged pipes and fittings to be formed in an assembly including a peripheral clamp and gasket, and a system, method and kit for effecting structural and water tight joints in corrugated plastic pipe pipes.


1. An assembly of collinearly aligned sections of large diameter corrugated plastic pipes that are buried in a trench comprising a plurality of separate lengths of connected pipes wherein: A) the end of a first pipe length abuts the end of a second pipe length, and each pipe length includes a flange radially extending from the abutting ends of the pipe lengths, and each flange radially extends from the valley of the corrugation in the pipe immediately preceding the end and does not transversely extend into a crest, and B) a circumferential clamp is dispo...
