Double-See

This vinyl double containment piping system is fast and easy to  install, and is available with a complete selection of pipe, fittings,  and valves. Additionally, an innovative “valve-in-valve”  design is offered which allows full containment pressure rating.  Double-See™ is available in PVC and CPVC; either material may be  primary or secondary (PVC x PVC, CPVC x PVC, CPVC x CPVC) with Clear  PVC always being an option for the containment pipe. System size  options range from 1/2″ x 2″ to 6″ x 10″, meeting  virtually any application requirement. Installation versatility allows  simultaneous joining throughout a system or in combination with  patented closure couplings which enable practical compliance with the  ASME B31.3  requirement for visual inspection of all primary  joint connections during the pressure test before closing the  secondary piping joint.

Double containment piping systems are ideal for ensuring safety when  transporting corrosive, toxic, or otherwise hazardous media.

When a leak from the primary pipeline occurs in a double containment  system, the fluid is safely contained by the secondary pipe. End-users  typically implement a leak detection system to alert operators when a  leak has occurred.

These systems can be used in multiple applications, primarily for  handling chemical and effluent water transfers.
