West Well Polytubes are manufacture Of PLB Duct Pipes from High Density Poly Ethylene (HDPE) and are coated inside with Silicon for permanent lubrication that aids in easy installation as conduits for underground cabling. These are manufactured at our state-of-the-art extrusion plants as per DOT Specification GR/CDS-08/02 Nov. 2004 amendments.
PLB Pipes are used as underground cable conduits for optical fiber cables, communication cables etc. & are suitable for cable installation by blowing tor pulling by rope techniques.

West Well Polytubes was one of the first very few manufacturers to acquire technology and equipment for establishing complete manufacturing facility for PLB-HDPE Ducts.

At West Well Polytubes, PLB Pipes (duct pies) are manufactured using ultra-violet (UV) stabilized grade of HDPE with required Anti Oxidant content and other recommended additives. The inner layer of ducts is duly silicon coated which minimizes the friction between OFC and the duct during the process of blowing the cable into the ducts, thus providing smooth installation of OFC in the duct without damaging the cable fibres.

West Well PLB HDPE Duct

We are supplying Permanently lubricated HDPE duct by the brand name of West Well. They result in-

  • Faster and easy installation of cable with lesser manpower.
  • Feasibility of longer lengths installation.
  • Reduction in installation cost, maintenance and future up gradation.
  • Easy movement of cable through bends.
  • Reduction in number of joints due to longer lengths of pipes.
  • Existing cables can be deployed after blowing from the duct.
  • The pipes are non toxic in nature and hence safe to handle.


  • Telecommunication.
  • Railways information Network.
  • Computer Networking.
  • Cable Service Providers.
