Electrical system
The pipes are produced and delivered in coils of different lengths, depending on the pipe diameter.
The joint between the coil ends is made either by welding or by means of compression fittings.
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 pipes are produced in bars, especially 6 m in length, but for some diameters they are also produced at a length of 4 m.
