The manual scraper is an essential accessory for the electrofusion welding process on any plastic pipe. In the case of this scraper valid for scratching pipes from 63 to 400mm, it is used to remove the oxide layer (shine) from the outer surface of the pipe manually.
This scratching is done so that the oxide layer does not harm the correct union of the accessory with the pipe.
The scraper incorporates a thin sheet of hardened tungsten that generates a cut with a controlled depth by scraping only 0.3mm from the surface of the tube. Fast and perfect scratching.
