High-pressure PTFE hoses

 High-pressure PTFE hoses provide a flexible link between various units of machinery and equipment operating at a high vibration level, under pressure fluctuations and hydraulic shocks caused by the working fluid. High-pressure hoses are used in many types of industrial and transportation equipment. Being strong and flexible, they are used to feed motor oils, gases, liquids, fuels and lubricants under a high pressure.

PTFE makes hoses resistant to almost all known corrosive mediums and prevents mediums from sticking to pipe surfaces even at high temperatures. PTFE hoses have a low flow resistance compared to metal hoses, a high cleanliness of working surfaces, and they are protected from electrostatic charge.

The main feature of PTFE hoses is a flexible pipe made of a hardened PTFE tube that is covered with one to three outer layers of corrosion-resistant wire and, optionally, with a protective polymer coating. It is also equipped with end fittings.

Our original solutions and the use of unique equipment are at the core of the production process at the plant. Our high-pressure PTFE hoses can be used:

  • in pumps for pumping corrosive liquids, crude oil, gas condensate, oil water and groundwater, as well as for delivering purified water while cooling nuclear reactors;

  • in hydraulic systems of machines and mechanisms;

  • for canning corrosive substances from machines, barrels and tanks;

  • for supplying gas and petrol at filling stations;

  • for supplying gas to household gas stoves;

  • for supplying concrete grout, paint or varnish;

  • as automotive fuel hoses.

Operated temperatures range from -60 °C to +230 °C.

Some features of high-pressure metal braided PTFE hoses include:

  • they can operate at a bend of up to 10 NPS (with NPS up to 15mm) or up to 20 NPS (with NPS more than 15 mm);

  • they are pressure-tight at 1.5 NP;

  • they have a 3:1 safety factor (the burst pressure is 3 times the nominal pressure).

  • if operated at temperatures above +230 °C, they lose operating pressure which amounts to 60-70% of nominal pressure.

All of our high-pressure PTFE hoses are produced in accordance with technical standards (TU) and the state sanitary norms and regulations.
