Flexible Dual Containment – Chemical Dosing Hose

Flexible dual contained chemical dosing hose with leak detection.

Our flexible dual contained chemical dosing hose will save you time and money compared to traditional pipe-in-pipe systems. The two systems, PF Detect and Protectaflex, both consist of a durable PU outer jacket and an inner hose in a choice of materials (reinforced PVC, LDPE and PTFE).

The main difference between the two products is the leak detection system:

• PF Detect – offers built-in leak detection, which only requires a minimal amount of liquid to trigger the alarm and shut off procedure, with the leaked liquid contained by the versatile polyurethane jacket.
• Protectaflex – uses system-designed catchpots, which enable the outer containment to be terminated inside the catchpot.

Both products share some common features and benefits:

• Made from a light and supple material, and it relies on capillary action rather than gravity to work, meaning it can be installed almost anywhere.
• Lightweight meaning lower shipping and storage costs.
• Good flexibility and lower bend radius
• Easy to handle and install, for example, flexible hose can often be installed via a duct so there is no need for expensive and disruptive excavation works.
• Fittings can be swaged on, offering a comprehensive coupling, eliminating the risks of clips and the need for expensive bespoke dual contained fittings.  Only one standard hose tail fitting required per end.  (Click here to find out which hose tail you need)
• Hose can be delivered in continuous runs with no joints up to 500m, meaning you only require one fitting for each end on half a kilometre of hose
• Reduced packaging and fully recyclable resulting in a lower carbon footprint
• In tests, the PU outer did not distort when the inner hose burst.

PF Detect

PF Detect was originally developed for the chemical dosing market to further reduce environmental leakage risk. In the unlikely event of a leak, the built-in leak detection means that the moment there is a problem, an alarm sounds, sending a signal to switch off the dosing pump and allowing you to get your reserve line working within seconds.

With attractive per metre costs and the potential to forego the expense of catch-pots, PF Detect allows you to save money and add value, without cutting corners.

Our flexible hose is now available in purple (subject to minimum order quantities) making it immediately apparent that chemicals are passing through the pipe.
