Underground Sewer PVC Pipes

PVC pipes are commonly used for underground sewer systems; Haykal Plast manufactures PVC pipes for underground sewage systems according to EN 1401 and DN 19534 standards. Our range is KIWA/KOMO certified and manufactured according to the highest European standards. Haykal Plast’s clients for sewage systems and pipelines include the Lebanese Government, local market and international markets.

PVC pipes for underground sewage systems at Haykal Plast range from 50mm to 400mm, and are fitted with Push-Fit (R.R.) sockets.

PVC Pipes have different applications and can safely be used in the following areas:

  • Cable ducts for electrical and telecommunication cables.
  • Ventilation and soil waste elimination in buildings.
  • Underground drainage and sewer pipes.
  • Water Distribution.

Storage & Transportation

  • Pipes are stacked on a flat and level surface.
  • Surface is free from any sharp object that may result in irrepairable damage or deformation.
  • Loose pipes are stored on a stable platform.
  • Loading pipes on the vehicle is done with great care to avoid impact damage.
  • Off-loading pipes is done by rolling them gently over timber assuring no damage is done to the pipe.

Do not drag pipes across the ground and avoid sharp edges.


PVC Pipes Benefits

There are many different types of pipes available on the market, but PVC pipes have diverse benefits that make them ideal for use:

  • Low weight.
  • High impact/tensile properties.
  • Good hydraulic properties.
  • Low friction coefficient: The smooth inner surface of PVC pipes allows a significantly greater flow compared to other non-PVC alternatives.
  • Chemical resistivity: PVC pipes are resistant to damage from alkalis and acids.
  • Electrical resistivity: PVC pipes are non-conductive, and are thus not affected by electro-chemical corrosion.
  • Flame resistivity: PVC pipes have a high kindling point (exceeding 450° Celsius), and they are self-extinguishing.
  • Abrasion resistivity.
  • Greener Technology: PVC pipes use less renewable resources.
