Polyethylene water well pipes


In addition to the aforementioned, our company also manufactures polyethylene pipes and screens (High Density Polyethylene Pipes- PEAD) with threaded connections. These pipes are utilized in waste collection and transportation as well as fermentation gas transportation.

Polyethylene pipes are manufactured in compliance with national and international standards and are suitable for transportation of water and gas under pressure.
 
The principal features, which make polyethylene pipes exceptional, are the following:

    - High resistance to vibration and stress caused by water.
    - Flexibility.
    - Low weight.
    - Possibility of easy interconnection
    - Non-toxicity
    - Proper behavior in low temperatures
    - Resistance to corrosion and chemical agents.

The broaching of screw threads on polyethylene pipes and screens is effected by a special CNC threading machine tool.

Manufacturing of screens is carried out using special machine tools, and the screens have a slot width of 1.5mm - 5mm, transverse to the pipe axis.
