Features and benefits of PTFE
- Ability to handle a wide temperature variance: -60⁰C to +260⁰C
- Not affected by heat aging
- Compatible with a very wide range of chemicals
- Low permeability rates
- Not affected by Ozone or UV exposure
- Low co-efficient of friction—better system efficiency due to lower pressure drops
- Non flammable
- Superior flex fatigue life
- Low volumetric expansion
PTFE with its unique properties is ideally suited to the rigorous demands required by the Oil & Gas industry—from upstream exploring and drilling via distribution to downstream processing and refining of petroleum compounds, CNG, LPG, acids, alcohols and other derivatives, including the production of biofuel blends from various resources.
The PTFE Hose liner is virtually inert to all chemicals and solvents and has a wide operational temperature range of -60⁰C to +260⁰C.
Flexible PTFE hoses replacing pipework at the connection between the pipework and reaction vessel, loading cells or pumps are sufficiently flexible to take relative movement and thus the resulting strain on the vessel is negligible, where stainless steel pipework can crack or does not give the movement needed.
PTFE hoses do have self-cleaning capabilities, when compared to flexible stainless steel hoses that have deep annular convolutions which can trap chemicals and prevent them from draining away. Also, PTFE hoses are superior to flexible stainless steel hoses regarding flex fatigue, pin-holing and chloride stress cracking.
PTFE will not age and is UV, Ozone and weather resistant. PTFE has the lowest coefficient of friction of any solid known. No-sticking consistently ensures low pressure drops during service. The addition of a small percentage of carbon black to the PTFE also allows the PTFE hoses to dissipate any potential static charges for added safety.
