Duo-Pro dual-contained polypropylene, PVDF, and Halar piping systems are offered in sizes ranging up to 20 in. in diameter, making it possible to mix and match the carrier and containment pipe in different materials. Duo-Pro is appropriate for large, flexible systems, particularly in process waste lines, pressurized transfer lines, and drainage applications. Each system is constructed using a patented Dogbone fitting. The unique design of the Dogbone provides such advantages as safe transition from double-containment to single-wall systems, locking of the inner pipe to the outer pipe for proper stress control, and control of thermal expansion forces and system restraint.
