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. 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.
