Poly-Flo® is of unitary construction, extruded by a patented process, in sizes 1x2, 2x3, and 4x6, in polypropylene and HDPE. Poly-Flo is relatively inexpensive and extremely easy to cut and weld. Patented double O-ring flanges allow Poly-Flo systems to be efficiently pre-assembled, then easily bolted into place in the field. Poly-Flo pipe’s low cost and easy installation make it unbeatable for applications such as small laboratory drainage systems and pressurized transfer lines. Typical installations are in waste treatment, sulfuric acid or caustic soda; in chemical processing applications, for bulk storage chemicals such as sodium hydroxide and aluminum nitrate; and in semiconductor plants, handling sulfuric, nitric, and hydrofluoric acids for wet stations. 
The Poly-Flo System is a unique dual extruded and molded system. All other double containment systems are made from single wall components and then assembled into a double wall configuration. The Poly-Flo System thereby reduces fabrication resulting in significant cost savings. Asahi/America’s patented extrusion process locks the pipe together by use of continuous support ribs. This unique process is applied to molding fittings as well. The continuous support provides inherent restraint to expansion forces thus eliminating the requirement of Dogbone fittings in the Poly-Flo System. Poly-Flo’s patented double O-ring flanges allow systems to be efficiently pre-assembled then easily bolted into place in the field. The Poly-Flo system is available with manual and low point leak detection sensors only. The use of leak detection cable is not possible due to limited annular space.
