Double Wall Piping System

Dec. 16, 2014

Asahi/America, Inc. reintroduces the Poly-Flo® co-extruded double containment piping system. Available in black PE and euro grey PP-R, Poly-Flo® is ideal for installations with space constraints and systems where thermal expansion and contraction are present. Poly-Flo® is a complete system including full pressure fittings, drainage fittings and machined fittings. This SDR-designed system is available in 1x1-1/2”, 2x3” and 4x6” and operates up to 150psi at 68°F.  Because of its unitary construction, Poly-Flo® pipe and fittings act like a single wall system, which helps prevent failures often seen in fabricated systems. This is especially important in installations with fluctuating temperatures or applications like directional drilling where opposing forces act on the carrier and containment pipes.

Black PE Poly-Flo® is well-suited for outside, above ground applications because of its UV resistance, and it performs well in underground installations because of its resistance to crack propagation. Due to its high pressure rating, euro grey PP-R Poly-Flo® is ideal for applications running at higher temperatures. Water treatment facilities and chemical applications benefit from Poly-Flo’s® chemical resistance. The system’s low cost and easy installation also make it ideal for drainage systems, pressurized transfer lines, and industrial applications requiring up to a 4” carrier pipe. 

The Poly-Flo® double containment piping system is available with manual and low-point leak detection sensors. Joining the upgraded system only requires standard welding equipment; no special clamps or inserts are necessary. Asahi/America offers butt fusion welding equipment and weld training for all of its piping systems.
