May 7, 2011 - GF Piping Systems introduced Double-See, a pressure-rated double containment system for transporting hazardous liquids. The system offers a simplified installation method, a closure coupling design that allows conformance to the ASME B31.3 test inspection requirements, and 3D thermal expansion compensation. With Double-See system, both primary and secondary pipes are cut to the same length and can be joined simultaneously. This saves significant time and prevents potential mistakes caused by staggered pipe-cut measurement errors. GF's Double-See Piping System offers versatile installation options, assembled and tested fittings, and a unique pipe cut-length guidance system which provides a truly simplified approach to installation. The piping systems are available with a complete selection of pipe, fittings, leak detection and access tees, closure couplings and termination fittings. In addition, an innovative valve-in-valve design is offered that allows full containment pressure rating. Double-See is available in PVC and CPVC; either material may be primary or secondary (PVC × PVC, CPVC × PVC, CPVC × CPVC) with Clear PVC always being an option for the containment pipe. System size options range from ½" 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. In addition to providing the obvious benefits for safe transport of hazardous liquids, the Double-See Containment System fulfills local, state and federal environmental and safety regulations. The piping systems are suitable for a wide range of applications including water and waste water treatment, chemical delivery, dosing and processing, microelectronics, life sciences, metal working/finishing, waste collection, and many others.
