PTFE pipes

 PTFE pipes are meant for use in pipelines for the transportation of products that corrode steel. The use of PTFE pipes reduces the consumption of alloy steel and extends the life of pipelines. Moreover, PTFE pipes have a low thermal conductivity, which helps to reduce insulation costs, and they do not need to be painted in order to be protected against corrosion. In recent years, PTFE pipes have become very popular in the construction of industrial pipelines.

A high chemical resistance of PTFE products accounts for their use in transporting corrosive mediums. Their chemical resistance exceeds that of all known materials, including gold and platinum. Even a mixture of concentrated hydrochloric and nitric acids has no effect on them, and only chlorine trifluoride and fluorine can destroy them. This makes PTFE the most resistant material for manufacturing pipes and sealing parts of pipelines that transport corrosive mediums.

PTFE pipes have a large range of mechanical properties, a low coefficient of friction, low wear rates, are resistant to various corrosive mediums at room temperature and elevated temperatures, are durable and radiation-resistant, have a low gas permeability, are non-flammable or self-extinguishing when ignited. Strong oxidizers have no effect on them. They have a wide range of operating temperatures (from -60 °C to +250 °C), remain chemically resistant at high temperatures, and withstand a hydraulic pressure of up to 0.6 MPa.

We at Plastpolymer-Prom offer PTFE pipes with diameters ranging from 20 mm to 600 mm and a wall thickness ranging from 1.5 mm to 6.5 mm. All pipes have a length of 3 m. You can find more information about PTFE pipes on the page titled “PTFE products”.

Due to their unique properties PTFE pipes are used:

  • to transport any corrosive mediums (except molten alkali metals) at a medium pressure of up to 0.4 MPa;

  • to line reactors, fractionating columns, valves, pumps, and tanks for the storage of chemically active mediums;

  • to produce sealing parts in contact with corrosive mediums;

  • to produce sensors for flow meters and magnetic flow meters;

  • to produce suspension insulators for overhead railway electrification systems.
