Why do we use an HDPE pipe for underground

Update:08 Jul 2020

Kasta High-Density Polyethylene pipes exhibit better strength when compared to PVC. Kasta HDPE pipes are manufactured in greater lengths and diameters. Coiled lengths of Kasta HDPE pipes are available up to 1000 feet for certain sizes making it ideal for long runs with least number of joints. Apart from this feature, pipe lengths of Kasta HDPE can be heat fused eliminating toxic cement and resulting in stronger leak proof joints.


  • Long lasting
  • High Flow Capacity
  • Light in weight
  • Abrasion-resistant
  • Weather, corrosion & chemical resistant
  • Breakage Resistant
  • High resistance to direct sunlight
  • Easy jointing due to a quick coupling system
  • Precautions like cathodic protection are not required at the time of installation
  • Unaffected by earthquake & landslide
  • Being elastic, PE pipes require fewer fittings as compared to other fittings
  • Connection available even outside the trench

Advantages of using Kasta HDPE pipes:

  • The first and foremost advantage of using HDPE pipes is that they are lighter than the CI pipes and the GI pipes
  • Being easy to carry, Kasta HDPE pipes save transportation cost and handling charges
  • When it comes to transferring of heat, the rate of energy transfer is a lot low in Kasta HDPE pipes
  • Kasta HDPE pipes comprise of a smoothened out inner surface that restricts the formation of bacteria and microorganisms of any kind. This ensures the pumping process to be faster and smoother with the least amount of effort

Various kinds of uses:

  • One of the main use of Kasta HDPE pipes is supplying drinking water
  • Plays an important role in the field of irrigation
  • The noncorrosive nature of Kasta HDPE pipes make them more suitable for sewerage and sewage disposal
