Caldervale UNIPREP rotary pipe scraper

The Caldervale UNIPREP range of rotary pipe scrapers are used to prepare the ends of HDPE pipe and fittings for electrofusion welding. Pipe scraping is a critical step in the electrofusion welding process, removing the outer layer of oxidation on the pipe helps to ensure weld strength and integrity. The UNIPREP is affixed to the end of the pipe or fitting and rotated around its circumference, removing a thin layer of plastic. There are a range of sizes available, which are supplied in a steel transport case. See below for model specifications.
