Spiral-wound pipes, available with internal diameters up to 3,600 mm and various specifications, are manufactured from HDPE (High-density polyethylene) or PP (Polypropylene) raw materials depending on their intended use. The spiral-wound pipe's sockets are equipped with an electrofusion welding system. These pipes, which can be manufactured with gaskets, sockets, or butt welding, can also be manufactured for projects requiring specialized applications such as silos, tanks, and manholes.
