DEVICE FOR BAND-CONNECTION OF WASTE WATER AND SEWAGE PIPES

摘要

PURPOSE: A band-type drain and sewer pipe joint is provided to improve airtightness by maximizing the deformation of annular rims when a pipe is inserted into a sleeve. CONSTITUTION: A band-type drain and sewer pipe joint comprises a sleeve(20) and a fastening member(30). The sleeve is installed at the end part of a piping(10). A plurality of annular rims for airtightening is formed in the inner surface of the sleeve. The fastening member surrounds the exterior of the sleeve inserted and attached to the piping using a band. The fastening member is installed at an annular rod in both ends of the band and fastens the band.
