HDPE Piping System
Polyethylene(PE) is a sturdy thermoplastic material produced from the polymerization of ethylene and is widely used in water, slurry, and gas applications. Sangir HDPE pipes are manufactured in extrusion sizes ranging from 16 mm to 1200 mm. HDPE Pipes & Fittings are available in rolled coils of various lengths (up to 125 mm OD) or straight lengths up to 12mtrs. HDPE Piping System is available in wide varieties of wall thicknesses but is primarily based on Controlled Outside Diameter (DR). A promising material, it has a design life extended up to 100 years for some applications. Similarly HDPE Pipe is available in many forms and colors, such as the following:
– Single extrusion colored or black pipe.
– Black pipe with coextruded color stripping.
– Black or natural pipes with a coextruded colored layer.
