UN ACOPLAMIENTO PARA UNA UNION DE TUBOS CON SOLAPE.

摘要

A pipe lap joint is disclosed with an improved sealing zone structure in the overlap region of the pipe. The sealing zone comprises a pair of end-to-end intersecting slots which are covered by a clamping band and which allow the sealing zone of the pipe to be collapsed against the inner pipe when the clamping band is tightened. The outboard slot extends inwardly from the end of the pipe and terminates in a transverse end wall within the overlap region. The inboard slot is circumferentially offset from the outboard slot and extends inwardly from an outer end wall thereof. The adjacent sidewalls of the slots are in substantial alignment with each other and the end walls are also in substantial alignment with each other whereby the end walls of the slots are disposed in edge-to-edge engagement with each other when the overlap region of the outer pipe is collapsed into close fitting engagement with the inner pipe.
