Abstract

PURPOSE: To ensure to prevent the leakage of fluid for a long term by attaching and covering with soaked materials with resin adhesives, filling leaking gaps with the adhesives squeezed out from the soaked material, and sticking an elastic ring closely to the inside of a pipe in collars on both ends.
CONSTITUTION: A soaked material 11 of continuous foaming foamed body with cold hardening epoxy resin adhesives is wound along a rim groove 10a of an elastic ring 10 with a steel band 12 fitted inside. When the band 12 is gradually expanded in the diameter by means of a jig, the elastic ring 10 is pressed and stuck closely to a gas- leak part "a" inside a pipe, and at the same time, the soaked material 11 is pressed between the ring and the pipe. In this process, the elastic ring 10 is closely stuck to the inside of the pipe in collars 10b and 10c on both ends and small tongues 10d and 10e, and simultaneously resin adhesives contained in the soaked material 11 is squeezed out to flow in and fill up leaking gap "al" perfectly for preventing leakage in several stages.
