Brazing reinforced polypropylene pipes are produced using the same technology but with their own nuances. Usually, products made of reinforced polypropylene pipes have an increased diameter and do not fit the standard nozzles of the welding machine. Before the soldering process, they need to be cleaned using a device in a metal sleeve with knives. This device is put on the end of the pipe, and the reinforced layer is scraped off with rotary movements around the axis to clean plastic.
Another fixture is used on pipes containing a reinforced layer in the center.
