CONNECTING METHOD OF PLASTIC CORRUGATED PIPE

摘要

The connecting structure for offering complete water-proof effects and simplifying the connection work in connecting the resin tubes, comprises the two spiral tubes(1, 2) inserted to the spiral reinforced connecting tube(10) with thread-fitting; heat-shrinkable water-proof sealing(20) for winding the gap between the reinforced tube(10) and the spiral tubes(1, 2). The water-proof sealing has a tape form(22) and covers the outer peripheral surface of the reinforced tube(10) and both ends of the tubes.
