Manufacturer of High Quality HDPE Pipes

Why Select HDPE Pipe?

Pipes made from High Density Polyethylene (HDPE) is a cost effective answer for a number of piping problems in Metropolitan, Municipal, Industrial, Underwater, Mining, Landfill Gas extraction, Cable duct and agricultural applications. It has been tested and proven effective for underground, above ground, surface, under water as well as floating pipe applications.

HDPE pipes are strong, tough, non-toxic, light in weight and resistance to corrosion and have been widely adopted in a variety of piping system and are replacing most pipes of conventional materials.

Polyethylene pipes can carry potable water, wastewater, slurries, chemicals, hazardous wastes, cables and compressed gases as well as oils. Polyethylene pipes have a long and successful service experience to the gas oil, mining and water utility industries. PE pipes have the lowest repair frequency per Kilometer of pipe per year compared with all other pipe materials used for urban water and gas distribution.

Newtech HDPE pipes will meet all your requirements of long service, trouble-free installation, flexibility, resistance to corrosion and chemicals.

Benefits of HDPE Pipe:

  • – Light in Weight
  • – More Flexible than other metal based pipe, such as – GI, Stainless Steel, Black Iron, and Copper etc.
  • – Coating of the HDPE pipe is quite smooth.
  • – Capable to resist from environmental threat or Crack
  • – It can defy pipeline Corrosion
  • – Can protect form Frost & Rodent.
  • – Hygienically Safe (Food Grade)
  • – Easy to install and handle.
  • – There is a least chance to conduct heat.
  • – Abrasion free
  • – Has Long Life (approx 50 Years)

 

Typical Physical Properties of HDPE Pipe:

1.      Abrasion Resistance In tests, it has been proved that HDPE is superior even to X-52 grade steel when it comes to conveyance of iron ore water slurry. The performance ratio is 3:1 in favour of HDPE
2.      Flexibility The flexibility of HDPE pipe allows it to curved under, over & around obstacles as well as directional changes. In some cases, the flexibility of HDPE pipe reduces the need for fittings & saves installation costs. It can be bent to a minimum radius of 20 to 40 times the pipe diameter
3.      Flow Factors HDPE pipe has a smooth inner surface. A “C” factor of 150 is recommended in the William – Hazen formula. HDPE offers the unique advantage of choosing a pipe of a lower dimension for same flow of liquid over steel or cement pipes. Smooth inner walls & lower friction lead to energy saving in pumping of liquids.
4.      Life Expectancy The hydrostatic design basis of HDPE pipe is based on extensive testing data evaluated & standardized by industry methods.  HDPE has a projected life expectancy of 50 years transporting water at 30°C.
5.      Lightweight It is lighter than Mild steel, Stainless steel, Concrete & Cast iron.It is easier to handle & install as compared to above materials. Density = 0.95kg/cm2
6.      Pressure Ratings Depending on size & application, HDPE pipes as available in PN-6, PN-8, PN-10, PN-12.5 & PN-16
7.      Toughness HDPE has low notch sensitivity, high tear strength & excellent scratch & abrasion resistance. Its resistance to environmental stress cracking is outstanding
8.      UV Protection Black HDPE pipe containing 2.0 to 2.5% carbon black can be safely stored outside in the sun without damage from UV exposure.
9.      Welding HDPE pipe can be joined by mechanical & butt fusion methods. In butt fusion, the strength of the joint is stronger than the pipe itself & the welding is homogenous. It can be flanged, tapped, reduced like other piping materials.
10.  Coiled Pipe HDPE pipe is available in coil form upto 100 meters in single length in sizes 20mm Ø to 90mm Ø. It leads to significant saving in installation / Jointing costs.
11.  Corrosion Resistance Corrosion resistant. Does not rust, rot, or corrode.
12.  Leak Proof Leak tight. Heat-fused joints create a homogenous, monolithic system. The fusion joint is as strong or stronger than the HDPE pipe itself.
13.  Jointing Polyethylene pipe is normally joined by heat fusion. Butt, socket, create a joint that is as strong or stronger than the pipe itself, and is virtually leak free. This unique joining method produces significant cost reductions compared to other materials.

 

HDPE Pipe Range & Production Capacity

HDPE Pipe is manufactured in diameters from 20mm to 63mm (in rolls of 100 Mtr), from 75mm to 90mm (in rolls of 50 Mtr) and the pipe having diameter from 110mm to 315mm is produced in straight lengths upto 12 Mtr) for pressure series PN-6, PN-8, PN-10 PN-12.5 & PN-16.

Please note, the Pipes of bigger diameter can be manufactured/supplied on special request
