Chem Proline is a crack-resistant polyethylene (PE) piping system designed for the harshest liquid chemical applications, such as those handling sodium hydroxide, sodium hypochlorite, caustic soda, and weak acids. The complete system includes pipe, fittings, valves, injection quills, and chemical feed skids. Made from the latest generation of PE resin (PE100-RC), Chem Proline pipe and fittings are a lower-cost alternative to metal, fiberglass-reinforced plastic, and lined-steel pipe, and they have a design life expectancy of up to 50 years.
