For this , we’re covering a system built for one of the most demanding requirements in fluid handling: keeping hazardous media contained, even when the primary pipe fails.
Federal regulations under 40 CFR 280 and 281 require that hazardous fluids be protected from escape in underground, exposed, and overhead locations. Asahi/America, Inc.’s Duo-Pro® Double Containment Piping System is engineered to meet those requirements without compromise. The system has been successfully installed in semiconductor, pharmaceutical, and chemical processing facilities, including applications at Fortune 500 companies.
Duo-Pro® uses proven, highly corrosion-resistant materials: polypropylene (PP), polyvinylidene fluoride (PVDF), and ethylene chlorotrifluoroethylene (ECTFE). Its mix-and-match design allows engineers to specify the carrier pipe material and pressure rating independently of the containment pipe, accommodating media and pressure changes within a single system. Components and prefabricated spools are welded by trained professionals and shipped fully fabricated, ready for installation.
Supply range covers 1×3 through 16×20. Pressure-rated configurations handle up to 150psi at 68°F. Drainage configurations are also available. Welding methods include simultaneous and staggered butt fusion. Leak detection cable can be installed in sizes 2×6 and larger. Dogbone® anchors provide the choice between a compartmentalized or restrained system.
Ideal applications include pressurized transfer lines, drainage, underground installations, and manufacturing.
