SYNTHETIC RESIN PIPE JOINT AND MANUFACTURE THEREOF

摘要

PURPOSE:To perform correct connection via heating by providing heating elements made of carbon fibers and electrodes on the connection faces of joint main bodies in a synthetic resin pipe joint melting and connecting synthetic resin joint main bodies and pipes. CONSTITUTION:In a synthetic resin joint melting and connecting synthetic resin pipes to be connected and synthetic resin joint main bodies 1 and 11, joint main bodies 1 and 11 are made of polyolefin resin, and heating elements 2 and 12 made of carbon fibers are buried in mating connection faces. Electrodes 6 exposed on the outside of the joint main body 1 are provided at both ends of the heating element 2. The heating element 12 is stuck with carbon fibers on a synthetic resin film, a constitution section is formed on the cylindrical heating element 12 with the film, and the heating element 12 is buried in the joint main body 11. No distortion or gap is generated near the heating elements 2 and 12. Correct connection can be performed with no leakage of a fluid in a pipe.
