HDPE Pipe For Water Supply

Even in heavy loaded areas, where only the strongest – Galvanized iron, Ductile iron, Cement Pipe survive, Plastic in the form of HDPE has scored beyond doubt as an ideal substitute. HDPE is today, the internationally preferred piping material across an unbelievable range of applications (where strength & long life is key requirements). HDPE is also capable of handling even semi-solid and gaseous effluents and displays unmatched resistance to corrosive chemicals. In other words, where metal, cement and other forms of plastics fail to perform, HDPE pipes excel.

HDPE Pipes are one of the two largest thermoplastic pipelines available and by far the most versatile. Polyethylene is a wax like thermoplastic with a density varying from a range of 934 Kg/m3 to 960 Kg/m3 which is less than that of water. The only two additives that are added to polyethylene are Carbon black with a limit of 2-3% to add some reinforcing effect to increase its weathering properties and some Anti-Oxidant to a limit of 0.3%. HDPE having comparatively high molecular weight is high in abrasion resistance and impact strength. It is also very good in stress cracking resistance and has low creep rupture properties. It is excellent in insulation properties over a wide range of frequencies and good chemical properties.


Features & Benefits of HDPE Pipes

  • Very low frictional resistance to fluid flow and thus saves energy cost for pumping.
  • UV resistant Low wear and tear and fully abrasion resistant. Remains free from incrustation throughout the life span giving better flow always.
  • Suitable to withstand high fluid flow and external soil pressure. Chemically inert and hence resistant to most chemicals and hostile corrosive soils.
  • Excellent impact resistance, withstands water hammer shocks and transverse loads due to thermal stresses. Bending radius is 25 times the pipe diameter. Excellent elastic properties ensure absorption of soil movements, stresses and Hydraulic pressure.
  • HDPE pipes are easier to handle & install compared to heavier metallic or concrete pipes. HDPE is about one-eight, the density of steel and thus does not require the use of heavy lifting equipment for installation.
  • CPE HDPE is BIS certified & manufactured in compliance with the relevant Indian standard IS 4984
  • Light weight facilitates easy handling and instant fixing. Joints obtained by Butt welding are homogenous and 100 % leak proof. Offers life of minimum 50 years.
  • Available in single coil in lengths as required particularly the smaller diameter pipes. No additional joints, sockets, etc. are required.
  • Ease of use with relining techniques avoiding opening of trenches, Outstanding ability to withstand Rapid Crack Propagation (RCP).
  • Full joint traceability, ideal for renovation work through pipe bursting techniques, No requirements for protective coatings.

HDPE Pipes – Transportation of Potable Water as per IS 4984:2016, ISO 4427-1:2007:

  • HDPE Pipes all over the world are widely used for conveyance of potable water, HDPE Pipes are non-toxic and do not impart any foul taste or smell to the water that is conveyed through it. They do not pose any damage through disinfectant also.

HDPE Pipes – Drainage & Sewerage Disposal as per IS 14333:1996: 

  • HDPE pipe for transportation of sewerage and industrial effluents are made as per IS: 14333:1996. The main advantages of HDPE pipes for conveyance of Sewerage and Industrial Effluents are.
  • Resistance to chemical.
  • Abrasion resistant.
  • Resistant to treated or untreated water.
  • Better mechanical properties including toughness.
  • Greater burst strength due to flexibility.
  • Excellent free flowing characteristics due to smoother inner surface.
  • Higher longevity.
