JOINT STRUCTURE OF SYNTHETIC RESINS PIPE

摘要

PURPOSE: A coupling structure of a synthetic resin pipe is provided to prevent the fluid leakage through a gap between a cut part of the synthetic resin pipe and a ring flange. CONSTITUTION: A coupling structure of a synthetic resin pipe comprises a first and a second ring flange(11a,11b), a sealing(12), and a pressurizing joint(20). The first and the second ring flange have a first and a second sealing groove(111a,111b). The first and the second ring flange are respectively combined on the cut section of a one side synthetic resin pipe(10a) and the cut section of the other side synthetic resin conduit(10b). The first and the second ring flange are connected to each other and the sealing is located on the first and the second sealing groove. The pressurizing joint covers the exterior of the first and the second ring flange.
