Code: 9375. We produce a double-walled plastic spiral hose, composed of a smooth inner layer of HDPE and an external corrugated layer in HDPE or PP.

The internal wall of the spiral pipe is smooth to allow water to flow away, while the external one is made up of a series of spiral corrugations in order to increase its mechanical resistance to crushing.

The spiral pipe for sewers and rainwater drainage is made in different diameters with a maximum diameter product of 2,500 mm.

The double wall plastic spiral pipes can also be used in these cases:

- underground drainage systems

- underwater drainage networks

- tanks – lamination tanks

- rain water treatment plants

- siphons special pieces - spillways, sand traps etc.

- technological tunnels - crossing inspection shafts, jump shafts, etc.

- ventilation

- cameras for remote controlled nodes

- drains

- silos

- pipes with solid smooth profile
