CONNECTION OF POLYOLEFIN PIPE

摘要

PURPOSE:To permit the connection having a high connecting strength and a high connecting stability by a method whrein the pipe and a coupling therefor are connected after the connecting surfaces thereof are heated to a specified temperature or higher and, thereafter, an adhesive is coated on the surfaces in case they are connected by utilizing polyethylene siries adhesives. CONSTITUTION:In case the pipe of polyolefin and the coupling of synthetic resin are connected by utilizing the adhesive of polyethylene series, the connecting surfaces of the pipe and the coupling are heated to a temperature 50 deg.C higher than the melting point of the adhesive and the adhesive is coated thereon to connect them. When the pipe and the coupling are formed by a water crosslinkable polyolefin, the adhesive of polyethylene series is preferable to be made of the water crosslinkable polyethylene.
