Pipe, Profile & Tubing Extrusion

Pipe is formed when plastics is extruded through a round shaping die, cooled in a water bath, and either cut and coiled. The most commonly used pipe materials are PVC and high-density polyethylene. Rigid PVC pipe is commonly used in building and construction for drain, waste and vent applications, and is processed on specialty twin-screw extruders; HDPE pipe is used for a wide range of industrial, electrical and drainage applications. Flexible pipe is often considered tubing. Tubing can be used in industrial (hoses), food (straws), medical (catheter) and a variety of other applications. Profile extrusions are typically used for windows, doors, siding and are typically made of PVC.
