HDPE PLB Duct Pipes or High Density Polyethylene Permanently Lubricated Ducts are the high flow capacity ducts, which offer a very high quality option for the underground laying of optical fiber cable (OFC). These PLB HDPE Ducts are mainly used for the purpose of laying Optical Fiber Cable as underground conduits. The HDPE Telecom Ducts are manufactured with the high density Polyethylene materials. The material, high density Polyethylene offers a great resistance against the heavy earth loads and is a great in offering the impact and crush resistance.

Single Wall Corrugated HDPE Sheathing Ducts is Creating world-class infrastructure is a need of modern India. To achieve the target of getting fully developed country by 2020, India needs to build roads, bridges, flyovers, offshore platforms, nuclear containment & similar civil engineering projects. These structures must be durable, world-class & at the same time economical. Most of these structures are internally bonded post-tensioned. Hence, Single Wall corrugated (SWC) HDPE corrugated sheathing ducts for post tensioning of these structures in place of conventional steel ducts to achieve complete corrosion protection for tendons.The concept which became popular in 1980 & 1990 in Europe and now soon after that it became popular around world because It offers complete corrosion protection to tendons & eliminates the threat to the structures. The minute friction co-efficient for strands inside SWC HDPE Sheathing duct enhance the fatigue life of tendons. HDPE ducts also ensure electrical isolation of the tendons which helps corrosion monitoring of tendons. 
Advantages

• HDPE SWC Sheathing Ducts have been proved superior over conventional Ducts/Pipes such as metallic galvanised ducts because of its air & water tightness property. Its additional advantages over conventional method of prestressing are given below :
• Corrosion protection
• Water tightness
• Easy Handling & speedy installation due to fewer joints
• Lower wobble co-efficient (k) & friction co-efficient () helps
• Electrical monitoring of tendons
• Corrosion monitoring of tendons is possible
• Enhances fatigue life of tendons
• Good impact & compression strength
• Good impact & compression strength
• Good Bond with Concrete
• High stiffness and Flexibility
• Chemically inert
• Environment friendly
• Joining is very easy
• Even when bent, cross section of the duct retains its circularity

Therefore these SWC Sheathing ducts are strongly recommended in all mega projects especially in marine climatic conditions & corrosion prone area. The SWC HDPE corrugated sheathing ducts for internal bonded post tensioning was introduced by the company just after it became most preferred product for the designers & the construction companies of India. HDPE Sheathing Ducts is having unique applications in various construction projects such as :

• Flyovers & Bridges
• Nuclear Containment
• Under Passes
• Tunnels
• Pipelines
