Plb Pipes

PLB Duct Pipes

BERLIA PIPES 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.

'BERLIA PIPE' was one of the first very few manufacturers to acquire technology and equipment for establishing complete manufacturing facility for PLB-HDPE Ducts.

At 'BERLIA PIPES', 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.


  • Environment Stress Crack Resistance (ESCR)
  • Impact Resistance
  • Crush Resistance
  • Low Coefficient of Friction
  • High Temperature Resistance
  • High Ultraviolet (UV) protection
COM-line Ducts are suitable for installation in the field dirt trenches, under sidewalks, roads, within communication networks, between communication centers and between cities. They can also be used in branch networks between cells, distribution cabinets, poles, in walls and within subterranean networks of homes, allowing the insertion of communication cables-optical or copper, as well as TV/cable aluminum coaxial cables. Cables can be inserted in through the pipe by blowing, with an internal air-pressure up to eight bars.

Note : All the specifications provided for PLB Duct pipes are as per TEC Specifications (BSNL/DOT).
