Smooth Bore Convoluted PTFE Hose

PTFE liner tube extended throughthe end fitting, and then flaredout to form the sealing face

TEMPERATURE RESISTANCEDepending upon operating conditions and type ofbraid, Bioflex is usable at temperatures from −94° F to +500° F (−70° C to +260°C).

PRESSURE RESISTANCEDepending upon operating conditions and type ofbraid, Bioflex is usable up to 1160 psi (3/8″ ) and 725 psi (1″ ).

VACUUM RESISTANCEBioflex is usable at full vacuum up to 266° F (130°C).Above this temperature, vacuum resistance is reducedby 1% per °C.

SIZE RANGEBioflex is available in bore sizes from 3/8″ to 2″ inlengths of up to 20 meters.

END FITTINGSSanitary Clamp, Flange, Cam Lock, RJT, SMS, NPT

Bioflex is a smooth bore, highly flexible PTFE linedhose. Its design gives customers the best of bothworlds – a smooth bore PTFE liner, with the flexibilitynormally associated with a convoluted hose.

Bioflex PTFE liner comprises internal rib sections(which support the tube against kinking, vacuum and pressure) and highly compressed web sections(which gives a smooth bore inner surface andexcellent flexibility).

COMPARISON WITH CONVOLUTED PTFE HOSE

• Hygienic Cleanability – vastly improved, due tosmooth bore and hygienically polished inner surface.

• Flow Rates – more than 100% higher.

• Pressure Ratings – more than 50% higher.

• Gas Permeation Resistance – more than 150% higher.

• Flex Life at Temperature and Pressure – more than50 times the life, dependent upon text conditions.

Bioflex is available with a choice of:PTFE LinersVirgin PTFE Liner – For use in applications where fluidsconveyed are not highly electrically resistive. The lineris manufactured from FDA approved hose grade PTFEmaterial.

Anti-static PTFE Liner – For use in applications whereelectrically resistive fluids such as alcohol, solvents or freons are being conveyed in order to prevent adamaging electrostatic charge build-up inside thehose. The liner is manufactured from FDA approvedPTFE and Carbon Black materials.

Hose BraidsStainless Steel Braid – is used in applications involvinghigh temperatures and working pressures. High ten-

sile grade 304stainless steelwire is used,to give maxi-mum pressureresistance and externalprotection tothe hose.

Polypropylene Braid – is often preferred in appli-cations involving frequent handling and movement of the hose, and where temperatures are within therange −22°F and +194°F. Polypropylene braid is light inweight, and is not prone to chloride stress corrosion.

Kynar (PVDF) Braid – is used where severe chemicalcorrosion conditions exist around the outside of thehose. This can happen when Chlorine and Fluorine arebeing transferred.

External ProtectionRubber Covered Hose – for applications where thehose may be subjected to rough treatment and severeexternal abrasion. Also for hygienic applications,where the external smoothness and clean ability of

the hose is of primeimportance. A smooth blue EPDMrubber coveris applieddirectly onto a SS hoseassembly.

For a semitransparent cover, we recommend siliconerubber. If required, a black anti-static rubber or afireproof rubber cover is also available. Other optionsinclude scuff rings and protection coil.

Trace Heated Hose – Bioflex Electrically Trace Heatedand Steam Trace Heated hose assemblies are customdesigned and built for applications where the tem-perature of the process fluid must be maintained as it passes through the hose – usually to preventsolidification or an increase in fluid viscosity.

Bioflex Specifications,Temperatures, Pressures

& Flow Rates

TEMPERATURE VS. PRESSURE

Due to its extremely strong con-struction, Bioflex has outstandingresistance to temperature andpressure, much higher than thatof conventional convoluted PTFElined hose.

TEMPERATURE VS. VACUUM

All sizes of Bioflex GP, SS areusable at full vacuum up to 130ºC.Above this, the vacuum resistanceshould be reduced 1% for everydegree above 130ºC.

FLOW RATES

The flow rates shown in the graphare for Bioflex hose in a straightconfiguration, using water as thetest medium.

In practice, flow rates will varywith hose flexing, fluid viscosity,end fitting design and otherparameters, but Bioflex hose flowrates are always 2–3 times betterthan convoluted PTFE hose.

NON-WHISTLING

The ‘whistling’ noises created by turbulent flow when steam or gases are passed through aconvoluted hose are completelyeliminated when using Bioflex.
