PE Double Wall Piping System

Asahi/America, Inc. introduces Chem Prolok™, the latest addition to their family of thermoplastic double wall piping systems to help meet EPA requirements for underground chemical transfer. Chem Prolok™ has been certified by NSF to NSF/ANSI 61-G to be safe for drinking water. Made of the highest stress crack resistant PE resin, Chem Prolok™ offers broad chemical resistance, low installed cost and safe long-term, maintenance-free service. Typical applications include water and wastewater treatment chemical feed systems, acids, caustics, sodium hypochlorite, mixed chemicals, compressed gasses and process piping, pressure or drainage. 

Available in pipe and fitting sizes from 1” x 3” through 12” x 16”, Chem Prolok™ is designed to safely convey liquid chemical applications with a pH range from 1 to 14. UV resistant, Chem Prolok® is suitable for both above and in-ground applications. Chem Prolok’s™ stress crack resistance eliminates the need for special backfill in a buried service saving time and resources. Chem Prolok™ can be installed with either low point or continuous cable leak detection systems to comply with local environmental or safety regulations. Designed to avoid risky mechanical joints, Chem Prolok™ is joined primarily using simultaneous butt fusion, which provides the highest joint integrity known in thermoplastic piping systems.
