GROOVED POLYETHYLENE TUBES FOR CABLE LININGS

PRESENTATION

The PEHD pipes PE 100 50 mm diameter are delivered in coils of 100 to 300 meters. They are black in color.

ADVANTAGES

PE pipes have:

  • Very smooth walls associated with a low coefficient of friction loss, allowing a large cable pulling ease without any damage over long lengths
  • Great flexibility
  • High resistance to soil aggression such as acids, bases and salts
  • Durable networks with exceptional impact resistance
  • Excellent dielectric properties
  • A very good UV resistance
     
APPLICATION AREAS

The technique of ‘cladding’ cable with PEHD pipes is applied to areas that concern the protection of buried cables for include:
To telephone networks
Transport electrical energy from low voltage.

CHECKS AND LABORATORY TESTS

-Dimensional controls (nominal thickness, outer diameter min, max, average outside diameter, length crowns).
-Pressure test
-Tensile tests / elongation.
-Determination of hot longitudinal shrinkage
These checks and tests are carried out according to well-defined frequencies.
