PE corrugated tubes are made with a ribbed outer and smooth inner surface. This type of tubes have high resistance sperm damage caused by hot and cold weather, and also have excellent resistance to chemical compounds and abrasion.
Pipes connect with a muff and rubber in one whole with a pipe or with a muff and a rubber piece separately from the pipe – depending on the manufacturer. The rib (outer) part of the tube serves to insert the rubber to allow better sealing with the socket. The pipes are made in accordance with EN13476-3, and are available in two classes: SN4 and SN 8, in length of 6m.
