Cable protection pipes

Protected corrugated PE pipe system

The corrugated flexible polyethylene pipe system for cable protection is a system comprising double-wall corrugated PE pipes that are used in applications where high ring rigidity is required. The corrugated pipes have a smooth interior wall from medium density polyethylene, and the exterior wall, from high density polyethylene, profiled and glued to the interior in the contact areas. The corrugated structure ensures pipe flexibility and minimum material consumption per unit of length for a given diameter and ring rigidity. The range of diameters is between 40 and 200 mm. The pipes are produced and delivered in coils of different lengths, depending on the diameter of the pipe. Each coil is provided with a special double socket for connection to the next section. 

PVC pipe protection system with smooth socket

Teraplast produces PVC-U pipes with compact wall, rigid, to protect the cables foreseen with a coupling socket in accordance with the SR EN 61386-24 standard in L and N classes. The two classes are the result of cable protection pipe classification according to their strength to impact as follows: Class L = light working conditions (at least 9 samples pass the impact resistance test with the 3kg hammer). Class N = normal working conditions (at least 9 samples pass the impact resistance test with the 5 kg hammer). 

Besides this classification, there is a classification depending on the compressive strength. Both Class L and Class N pipes are rated for compressive strength according to the following values: 250, 450 or 750 N. The class and impact resistance must be marked on the PVC pipes for cable protection. The diameter range is between 32 and 140 mm for Class L pipes and 63 and 250 mm for Class N pipes. The pipes are produced in bars, especially 6 m in length, but for some diameters they are also produced at a length of 4 m.
