Protecting Cables since 2008
PLB DUCT PIPES
Also known as the HDPE PLB Duct Pipes, these pipes are useful in communication lines which employ underground optical fiber cables as their main medium for the exchange of information. The optical fiber cable is always at the risk of getting damaged due to several environmental and physical factors and that is why it needs to be protected. That protection is offered by HDPE PLB Pipes. Let’s see what these pipes are all about.

What are PLB Duct Pipes?
PLB Duct pipes or PLB pipes are made of high-density polyethylene which is permanently lubricated to withstand probable damage to the underground optical fiber cables by covering them. PLB Duct pipe meaning can also equate to their effectiveness against the harm done by the heavy load of the earth to the optical fiber line.
What are major benefits of a PLB Duct pipe?
The HDPE PLB Duct pipe is beneficial to the optical fiber cable line in the following manners –
- PLB HDPE Duct pipe offers a great Environmental Stress Crack Resistance.
- A PLB Duct meaning to protect an optical fiber cable line protects it from the impact and crush of its surroundings.
- The pipe is light weighted and is easy to transport.
- The pipe provides great resistance against temperature.
- It also happens to have a low coefficient of friction coefficient.
