Document Type and Number:
WIPO Patent Application WO/2020/235867
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 being coupled. To this end, the coupling assembly according to the present invention includes two or more couplers which are arranged facing each other in order to connect pipes continuously disposed in the axial direction, and the pipes are connected to each other 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 between the pipes and the catch parts to allow the outer circumferential surfaces of the pipes to pass through between the temporarily assembled couplers.
