METHOD FOR JOINING RESIN PIPE

摘要

PURPOSE: A method for joining a resin pipe is provided to improve a working ratio and increase an intensity and tightness by melting and joining a joining part of a circle resin pipe by an infrared ray heat source. CONSTITUTION: Thermal films(40) are arranged at an inner side surface of a connecting member(20) and a surface portion of resin pipes(10,10a). Each of the infrared ray lamp(30) is formed by a polyethylene system black film. The thermal films(40) quickly absorb and simultaneously transfer an external infrared ray heat source. An infrared ray lamp(30) is arranged at a predetermined point of the connecting member(20). Vertical and horizontal surfaces of pipes are melted and joined by a melting heat induced by means of the thermal films(40) based on an infrared provided from the infrared ray lamp(30).
