LLC “Kalan” produces filtrating pipes of fibro-porous polyethylene for making filters on steel and plastic hoisting pipes for well site construction.
Appropriate sizes of steel (plastic) and filtrating pipes as well as prices for filtrating pipes are presented in the chart.
Certain advantages of our pipes over metal scales and filters of polymers of other producers:
- No susceptibility to corrosion;
- No susceptibility to fouling by hardness salts;
- Various nomenclature of pipes and possibility to expand it;
- Possibility to make pipes of any length up to 3-4 meters;
- Possibility to make pipes with any wall thickness from 4 till 15 mm and any porosity from 10-20 till 300-500 mym;
- Pipes are made without frames that’s why much cheaper while in shipment – it is possible to make a filtrating pipe entirely of our material.
