Smooth Flow:
The flexible Smoothbore PTFE Hose
Smooth Flow is the premium non-convoluted, ultra hygienic flexible PTFE hose.
With an embedded stainless steel vacuum spiral and 304 stainless steel over braid as standard, it has achieved success in a wide range of sectors but the most notable are pharmaceutical and food industries where Smooth Flow's high flexibility and its easy to clean design excel.
Smooth Flow is firmly established as a market leading product offering, quality, reliability and cost saving whilst maintaining a long service life equivalent to the competition.
Smooth Flow holds excellent vacuum and pressure ratings, even at elevated temperatures. This allows the hose to withstand conditions where conventional hoses would fail. Many users revert back to convoluted hose designs in such environments, however Smooth Flow will continue to perform and outlast its rivals.
Choose when dynamic endurance, product viscosity, contamination hazard, turbulence, flow rate and hygienic cleanability are areas of particular concern. The spec sheets across highlight the available braid options for Smooth Flow along with their capabilities. In certain circumstances special materials such as Monel braids are available.
Smooth Flow is available in complete assembly form only, so you won't find this hose anywhere else.
Excellent Vacuum Resistance
A smoothbore PTFE hose with an added vacuum spiral offers opportunities most other hoses cannot. The vacuum spiral enables this hose to withstand vacuum ratings up to 947mbar in sizes ranging from 1/2" to 2". The spiral helix provides the added benefit of preventing the hose from being kinked.
This makes Smooth-flow the ideal hose when faced with suction, high levels of vacuum or applications involving steam.
The added reinforcement prevents liner collapse enabling the hose to have a much longer service life.
Braid Options
-
Stainless Braid - This hose is available with a 304L stainless braid as standard which is suitable for several applications. It also offers the highest temperatures (-70°C to +260°C) and working pressures alongside strong external protection.
-
Polypropylene Braid - A polypropylene braid is available as an alternative. This is ideal for hoses which are frequently handled thanks to its lightweight design. Polypropylene is more limited to lower temperature and working pressure environments. However, it has good chemical resistance against a wide range of chemicals.
-
PVDF Braid - Offering excellent compatibility with the majority of chemicals PVDF is the option to choose when the hose is subject to the harshest of environments. As with polypropylene it is only suitable in lower temperature and working pressure environments.
-
EPDM/SI Cover - This variant adds either a vulcanised EPDM rubber or silicone cover over the top of the 304 stainless braid creating abrasion resistance and an easy to clean cover. Excellent for hygienic applications.
Available Fittings
Smooth-Flow PTFE hose is compatible with a wide range of fittings available in mild or 316 stainless steel. The hose can be combined with hydraulic fittings such as BSP's NPT's JIC's etc. but is primarily used with flanges (ANSI/PN) and hygienic fittings such as Triclamps, SMS or RJT couplings. This is due to the unique design of the hose which allows the PTFE liner to be 'flared' through the fitting. PTFE lined fittings are generally manufactured from 304 SS as the PTFE liner offers superior protections versus aggressive chemicals.
Alternatives
Our Core-Flow hose is an excellent alternative when hose flexibility is an area of particular concern. With only shallow convolutions sediment build up is prevented whilst still offering similar performance characteristics to Smooth-Flow making it an ideal convoluted hose for hygienic applications.
Speed-Flow is the standard smoothbore hose suitable for fittings with hydraulic tails. This can be self assembled with our ferrule range making it ideal for general purpose environments. It is also often used in hygienic environments thanks to its smooth easy clean design.
