Hose Construction
Bioflex Ultra Hose Design Options
Bioflex Ultra Hose Grades are made up by combining the Design Options, which are defined by 2 letters as shown below, and fully described in the linked sections.
For example, “Bioflex Ultra AS, PB, SG” defines a hose with an Antistatic PTFE liner (AS) and a Polypropylene braid (PB) and an outer Safegard (SG) spiral HDPE protection sleeve.
PTFE Liner Tube Options - GP (Natural PTFE) and AS (Antistatic PTFE)
Braid Options - TO (Tube Only, No Braid), SS (316 SS Wire), and PB (Polypropylene)
Rubber Cover Options - RC (Blue EPDM), BK (Black EPDM) and SI (Silicone Rubber)
External Protection Options - SR (Scuff Rings), SG (Safegard Spiral) and PC (SS Wire Coil)
Bioflex Ultra in Comparison with Convoluted PTFE Hose
- Hygienic Cleanability - much better, due to no internal convolutions
- Flow Rates - more than 2 x higher
- Pressure Ratings - more than 1.5 x higher
- Self Draining - Excellent self draining with PTFE lined fittings
- Non-Whistling - no whistling noise with gasses
Bioflex Ultra in Comparison with Conventional Smoothbore FEP, PFA or PTFE Lined Rubber Hose
- No Adhesives - No toxic adhesives used in the Bioflex Ultra construction, eliminating the possibilities of Process Fluid contamination in service
- Flexibility - Much better flexibility
- Internal Shape Control - No distortions in bore when flexed
Bioflex Ultra in Comparison with Silicone Rubber Hose
- Hygienic Cleanability - much better, due to the non-stick PTFE Liner
- Chemical Resistance - considerably improved, particularly to strong oxidising acids and bases
- Temperature & Pressure Ratings - much higher temperature and pressure capability
- Steam Resistance - permanently resistant to steam sterilising
(unlike silicone hose, which has a limited life)
