METHOD FOR CONNECTING RESIN TUBE TO ELECTRIC FUSION BONDING JOINT, AND RESIN TUBE FOR ELECTRIC FUSION BONDING JOINT

摘要

PROBLEM TO BE SOLVED: To provide a method for connecting a PE tube to an EF joint for obtaining a prescribed fusion bonding strength by preventing an adhesion of a cloud of soil dust or sand dust to a fusion bonding surface of the EF joint to the PE tube even when the dusts are whirled in an excavated hole and mounting a fusion bonding part of the EF joint to the PE tube in a normal state in a method for fusion bonding the EF joint to the PE tube.;SOLUTION: The method for fusion connecting the resin tube to the electric fusion bonding joint comprises the steps of coating an inner surface of the joint and a front surface of the resin tube or at least a surface to be connected of the tube with an antistatic agent (anti-electrostatic agent), and then fusion bonding the tube to the joint. In the resin tube fusion bonded by the joint for the joint, a pellet-like antistatic material is kneaded and molded when the resin tube is manufactured.;COPYRIGHT: (C)2001,JPO
