DWC Sewerage Pipe

What to check while buying DWC pipes?

Pipes placed underground require special provisions and durable designs to withstand wear and tear that pipes placed above the surface do not suffer from. Nowadays people prefer HDPE double wall corrugated pipes to lay underground for water transportation and such. HDPE double wall corrugated pipes are similar to normal HDPE pipes, except that they have two different designs on the interior and exterior surface of the pipes. HDPE stands for High-Density polyethene, which is extremely durable and offers a high life expectancy. They do not require much maintenance and can be installed underground without any care or constant cleaning even for years. Another unique feature of HDPE double wall corrugated pipes is that its inner wall is smooth-surfaced and polished to facilitate uniform flow of water, whereas its outer surface is profiled and corrugated to stand even under excessive load above the surface with optimum strength. Underground drainage and sewer application

  • Extremely light weight and strong.
  • Almost 60% of the weight is removed by setting up solid walled pipes.
  • The corrugated design gives the required strength for the outer wall to withstand pressure and forces in the soil.
  • Due to low weight, it can be easily set up with less manpower itself, and can be installed even in cramped areas.
  • Leakage-proof
  • Leakages are extremely unlikely due to the tight joints and firm design of the structure.
  • They come in sizes slightly longer than normal pipes, which reduces the number of joints and the chances of leakages.
  • Flexibility
