<p>PROBLEM TO BE SOLVED: To eliminate the cleaning of a polyethylene pipe after scrape work by a method in which when a thermoplastic resin pipe is fused with a joint, during the scrape work of the pipe or after the end of the work, static electricity generated on the surface of the pipe is eliminated. SOLUTION: While a pipe of a thermoplastic resin such as polyethylene and polypropylene is scraped, air ionized by using a blower is sprayed to a scrape surface, and during scrape work or after the end of the work, static electricity generated on the surface of the pipe is eliminated. In this way, the pipe is inserted into a joint and fixed to a clamp. Next, after a fusion tool terminal is fitted to a joint terminal pin, they are fused, and after being allowed to stand, the terminal and the clamp are released so that the pipe and the joint are fused. In this way, the cleaning of the polyethylene pipe after the scrape work can be eliminated.</p> |
