PTFE pipe linings provide chemical resistance at temperatures up to 300ºC. As their carbon chains are completely fluroinated, PTFE is chemically inert to the following range of commercial chemicals:

  • Acids including hydrofluoric, hydrochloric, sulphuric and aqua regia.
  • Chlorides, organic and inorganic
  • Sulphates, organic and inorganic
  • Bleach solutions
  • Solvents
  • Phenols
  • Caustics
  • Peroxides

Combined with the chemical inertness of PTFE are its non-stick properties. PTFE lined pipe systems minimise build up of deposits on the pipe walls, which can reduce flow and affect processing operations. Pacific Hoseflex offer the following products:

  • Lined spoils
  • 90 deg and 45 deg elbows
  • Equal tee and equal crosses
  • Reducing and instrument tees
  • Reducing flanges
  • Concentric and eccentric reduces
