Even in heavy-land areas, where only the strongest –galvanized iron, cement and asbestos survive; plastic, in the form of High Density Polyethylene (HDPE) has scored beyond doubt. It is very much essential to define strength of the material at a given reference life time. HDPE has a projected life time of 50 years transporting water at 30 deg. C. However, with safety factors in consideration actual life time is much beyond 50years.
The pipes are available in PN 2.5 to PN 16 pressure class in PE63, PE80 and PE100 grade. Chetak PE pipes are manufactured according to Indian as well international standard. It is technically superior, cost effective and offers mini advantages over conventional products.
Butt Fusion Welding is a time saving, highly economical, simple and widely accepted reliable method of jointing HDPE pipes. It is a permanent jointing method by homogenous fusion of pipe material under heat and pressure.
Small sizes from 20mm to 110mm HDPE pipes by heating mirrors of 220 volts and are manually done without using any jacks. However, for sizes above 110mm upto 250mm mechanical jack to ensure proper pressure and alignment while fusing the two pipes. For sizes above 250mm hydraulic jacks makes job simpler and reliable exerting correct pressure and alignment resulting in perfect joint.
