PTFE pipes are used in the following fields of industrial production:

In the chemical industry:

  • for producing pipes designed for transporting corrosive or extra-pure process mediums;

  • for lining steel pipes and their fittings, as well as chemical plant units operating in contact with corrosive mediums at temperatures ranging from -60 °C to +250 °C.

In shipbuilding:

  • in units and mechanisms of ships and submarines operating in seawater and exposed to fouling.

In the food industry:

  • as the outer layer of dough sheet rollers.

In the pharmaceutical industry:

  • in pipelines for transporting extra-pure substances.

  • In heating and water supply networks:

  • in flow and heat metering devices.

Our company produces pipes of large diameter (up to 600 mm).
