Thermoplastic fluid flow technology company Asahi/America’s Poly-Flo® co-extruded double containment piping system is available in black advanced polyethylene (PE) and euro grey polypropylene (PP-R). The Poly-Flo is said to be ideal for installations with space constraints and systems where thermal expansion and contraction are present.
Supplied as a complete system, it includes full pressure fittings, drainage fittings and machined fittings. This system is available in 1x1-1/2”, 2x3” and 4x6” and operates up to 150psi at 68oF.
The unitary construction of Poly-Flo helps prevent failures often seen in fabricated double wall systems. Design and installation considerations are minimized because Poly-Flo reacts like single wall systems, the company said. 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 advanced 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.
