It is possible to connect the pipes with the socket with rubber bend, which is inserted into the third channel of corrugated pipes between ribs, after that greased socket is inserted over the rubber bend onto the pipe. Pipes can be cut down with ordinary or saw. All parts of the pipes can be used by putting them together. PEHD pipes are lighter than PVC pipes intended for the same purpose, which makes it easier to manipulate and install them. They are highly resistant to aggressive chemical environment and the surrounding ground. It is possible to lay and use PEHD pipe lines at temperature range from -40°C up to +60°C. Smooth inner surface has a low coefficient of friction; which is why these pipes have very good hydraulic characteristics. They are highly resistant to abrasions. They have excellent mechanical and physical features.
Pipes are resistant to UV radiation, and they can be stored outside for period of one year, for longer periods they should be protected. It is necessary to make sure that while transporting and placing the pipes they are not to be dragged over sharp edges, because they can be damaged. On the other hand, these pipes are highly resistant to impact with dull objects. Pipes are certified by the Institute for raw materials of Republic of Serbia.
