High density polyethylene shielding pipes are designed for the construction of cable drains and cable pipelines, as well as parts of the distribution system. They are also used as shielding pipes of various types of power, signalling, telecommunication and cable television cables. They are produced in black as standard. The inner surface of the pipes is grooved. On the inner surface of the pipe, a sliding layer can be applied to reduce the force needed to pull the cable. The sliding layer is made of specially selected plastic ensuring, on the one hand, its durability, and on the other hand the volatility of the properties during the service life. The pipes are also produced in versions with longitudinal strips in the agreed colour and Cable is installed.
