Marking and scraping: In order to achieve a good weld the outer oxidized surface of the pipe must first be removed. Mechanical peeling tools are strongly preferred, as they achieve a consistent pipe surface preparation. Hand scraping is less recommended due to inconsistent peel strip removal and is known to be time consuming and onerous to adequately prepare a complete pipe end, particularly for larger diameter pipes.
Clean pipe ends on the outside with Plasson Pipe wipes to remove any rough dirt that might damage the tools used.
Mark the required scraping length Before scraping the pipe, measure the insertion depth of the fitting. With the fittings still in the bag, place alongside the pipe end and put a witness mark on the pipe at half the fitting length plus about 2cm to enable visual checking of the scraped area after jointing. Scrape pipe and spigot ends on fittings up to measurement mark to remove all oxidation and contaminants. Use Plasson rotational scraper.
