It is important to stabilize the scraped surface of the polyethylene pipe, even if some operator scrape the surface of the polyethylene pipe. In Japan this automatic saddle scraper is widely used for improving workability and plumbing quality
The newly developed “Automatic saddle scraper” consists of the casing unit with special scraping blade, driving unit, and the electric drill. The Casing unit is specifically required for each diameter of pipe to scrape. The other all units can be commonly used. This automatic saddle scraper can scrape complete periphery of the polyethylene pipe after firstly indicating the required fusing zone on the polyethylene pipe, then drawing round the outer circumference of the saddle by a marker pen, then hatching the area of the outer circumference of the saddle. The tool can scrape the surface of the polyethylene pipes with an outer diameter of 63mm to 125mm.
