Plastic corrugated pipes and tubes are an ideal solution for electrical conduit and cable ducting and can be found within the walls of buildings as well as underneath the ground below roads and walkways.

Corrugated electrical and cable ducting protects critical infrastructure from being damaged, including electricity, telecommunications, lighting and many other utilities. Commonly used materials include polyethylene (PE), polypropylene (PP) as well as PVC (polyvinyl chloride).

Some of the advantages of plastic corrugated pipes for cable protection include:

• Produced in continuous length, minimizing the number of required joints

• Coilable, easy to transport

• Flexibility allows installers to easily lay pipes around obstacles

• Outer corrugated layer provides strength while minimizing weight for ease of transport and installation

• Smooth inner layer minimizes friction and enables easy cable pull in

With extensive experience in pipe and profile design, QET corrugators are capable of producing a wide variety of corrugated electrical conduit and cable protection solutions:

• Single, double or triple wall pipes

• Traditional corrugation profile or spiral pipe

• Large range of pipe sizes

• Round or oval corrugated pipe profile

two types of pipe corrugator:
Internal blow moulding
Vacuum forming

Blow Moulding:
This technology consist of blowing low pressure (0,1-1,5 bar) through the die head spider into the center of the continuously extruded hot plastic tube. The air is retained by a plug with metallic or silicone washers.
The hot plastic material is expanded by the internal air pressure against the corrugation machined in the mould blocks which chill and holds the tube against the moulds to provide the desired geometry. Corrugated products formed by internal air must have constant I.D. dimension.

Vacuum forming:
This technology consists of pulling the hot plastic tube against the mould blocks by vacuum suction applied through the moulds applied to the plastic tube outside diameter surface. Vacuum from the moulds keep the tube against the moulds to provide the desired geometry. Corrugated products formed by vacuum may have variable I.D. dimensions.
