Standard PTFE lined hose systems can be the most economical solutions for conveying or treating highly corrosive fluids under severe service conditions.
PTFE, or Polytetrafluoroethylene, comprises long-chain molecules of carbon atoms, each linked to two fluorine atoms.The fluorine atoms provide a helical spiral which surrounds the carbon chain and protects it.It is this structure which creates the unique properties for which PTFE is well-known.
Excellent Chemical Resistance
PTFE is renowned as the most chemically resistant material known. Only a very few, very unusual substances and conditions can affect it, like Fluorine gas at high temperature and pressure and Liquid, boiling sodium metal.PTFE lined hoses can therefore be used for a wider variety of chemicals than any other hose type, making it the ideal choice for very corrosive chemical applications and multiproduct applications.
Non-Stick Surface
The use of PTFE as a surface for cookware products has demonstrated to the world how easily cleanable PTFE surfaces are.This means that PTFE lined hoses can be purged 100% clean more quickly, easily and reliably than any other type of hose.
Excellent Temperature Range
The cookware application also demonstrates another of PTFE’s many attributes – temperature resistance. PTFE itself can be used as a hose liner at temperatures from -150˚C up to +260˚C, dependent upon the hose design and the application conditions.This is the widest temperature range of any rubber or plastic hose lining material.
Hose Design
The only issue with PTFE as a hose lining material is the best way it can be integrated in to the hose design. This is where Aflex Hose have a proven record of success over the last 30 years.
