Dual Containment Hose

Dual Containment Hose


Dual containment hose is designed to prevent contamination to the environment in the water treatment and chemical industry. It is constructed from an inner carrier tube or hose that is used to convey the product and a clear PVC or polyurethane outer tube to provide containment in the event of a leak. PAR Group can supply pre-assembled dual containment hose in long lengths complete with the inner carrier tube threaded through the outer clear containment tube. Containment units can also be manufactured to catch leaks when a connection is required. The following grades are our standard options, but many other types are available and can be viewed on our flexible tubing page.  

Applications:

Containment hose is commonly used in chemical dosing, chemical transfer and water treatment applications.

Convoluted PTFE tubing is also available for increased flexibility and bend radius. PTFE outer containment tubing can also be supplied.

Technical Specification:
Note: Technical information is to be used as a guide only.  Pressure values given are based on the short term burst pressure at +20°C based on a 3:1 safety factor.  Any increase in temperature above +20°C will result in lower pressure values. These values may also vary depending on the hose manufacturer.  If the pressure rating is critical to your application please specify the required rating at time of enquiry.

Containment Units

Containment Unit  Containment Unit with Dual Containment Hose, Fittings & Clips

Containment units (also known as catch-pots) are commonly used in the water treatment and chemical industry to help contain chemical leaks from hose and tubing. In dual containment hose applications, containment units are designed to be fitted around the outside of the inner carrier hose where a connection is required.  This helps to quickly identify and contain any leaks from the joint. Containment units can also be used as a break in the outer containment tube with the inner tube remaining unbroken. This can provide a leak detection point. 

Our containment units are custom made from clear plastic and can be supplied curved or straight with a removable top if required. Pipe fittings and chemical resistant seals can also be incorporated.

Please enquire for more information.
