Document Type and Number:
WIPO Patent Application WO/2018/159927
Kind Code:
A1
Abstract:
The present invention relates to a protective socket-integrated water supply/sewerage pipe set having improved watertightness by preventing fracture of a connection end portion and detachment of a pipe and, more particularly, to a water supply/sewerage pipe set wherein the same comprises a water supply/sewerage pipe and a clamp; the water supply/sewerage pipe comprises a pipe body and a protective socket; the protective socket is integrally configured on the outer peripheral edge of an end of the pipe body; the protective socket has a protective ledge formed to protrude along the outer peripheral edge thereof; the clamp has a tightening portion formed inside one side thereof, has a detachment prevention ledge formed to protrude inside the other side thereof, and has a free movement space formed inwardly between the tightening portion and the detachment prevention ledge; the tightening portion tightens and retains the outside of the pipe; the protective ledge is positioned in the free movement space so as to form a space in which the protective socket can move freely; and the detachment prevention ledge is formed to protrude inwardly more than the outer diameter of the protective ledge without contacting the outer diameter of the pipe body such that, by connecting the pipe into the protective socket and by fastening the clamp, fracture of the connection end portion is prevented, fracture of the pipe body is prevented, detachment is prevented, and extending/contracting changes are allowed.
