Poly-Flo® (PP & HDPE) Double Containment Systems
Poly-Flo® is of unitary construction, extruded by a patented process, in sizes 1×2, 2×3, and 4×6, 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.
