Title:
COUPLING ASSEMBLY FOR CONNECTING PIPES, AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/010610
Kind Code:
A1
Abstract:
The present invention relates to a coupling assembly for connecting pipes, and a manufacturing method therefor. More specifically, the present invention relates to a coupling assembly for connecting pipes, and a manufacturing method therefor, wherein the coupling assembly can be installed in a state in which couplers are temporarily assembled using coupling members, and does not deform during a coupling process, and thus can be stably fixed even after coupling. To this end, the coupling assembly according to the present invention includes two or more couplers which are arranged so as to face each other in order to connect pipes continuously disposed in the axial direction, and connects the pipes in a state in which coupling members are temporarily assembled to the plurality of couplers. The couplers have catch parts which are inserted into coupling grooves formed in the pipes and have inner diameters corresponding to the outer diameters of the coupling grooves. Interference preventing grooves are formed in both sides of the catch parts and prevent interference of the catch parts and the pipes so as to allow the outer circumferential surfaces of the pipes to pass through between the temporarily assembled couplers.
