The quality and the life span of any pipe installation depends equally on both the geometric accuracy and the welding’s. Connecting pipes and fittings through melting takes just a few seconds. After a few minutes the welded pipe installation is ready to be installed. You cut the pipe, heat the fitting with the welding machine and then connect the two parts. That's all Fast, without substantial efforts and with wonderful result. All welded connections are completely safe because when the polypropylene cools down there's no change in its structure, shape or durability.
