A double-containment piping system with easier installation
The Double-See Vinyl double-containment piping system (photo) is a pressure-rated system with a primary (inner) and secondary (outer) pipe designed for safely transporting hazardous liquids. Both primary and secondary pipes are cut to the same length and can be joined simultaneously, which saves time with installation and prevents potential mistakes caused by staggered pipe-cut measurement errors, according to the manufacturer. Double-See is available in both polyvinyl chloride (PVC) and chlorinated PVC; either material may be primary or secondary, with clear PVC always an option for the containment pipe. The system provides a complete selection of pipes, fittings, leak detection and access tees, closure couplings and termination fittings. Other features include a 3-D thermal-expansion compensation centralizer, and a valve-in-valve design that provides full pressure rating in the containment piping.
