Chem Proline® System Components

Chem Proline Logo

Chem Proline® is composed of the latest evolution in Advanced Polyethylene (PE) resin technology. Advanced PE material possesses excellent physical and mechanical properties. These properties include: stress crack resistance, slow crack growth resistance, ductility, impact resistance, abrasion resistance and brittleness resistance. 

Capable of handling some of the harshest chemical applications with a long-term expected useful life, Chem Proline® offers a greater value over metal, FRP, lined steel, or other thermoplastic piping systems like PVC and CPVC. Chem Proline's superior properties make it the only Polyolefin material able to handle certain chlorinated services like sodium hypochlorite. UV resistant, light weight, proven fusion joining technology, Chem Proline® is perfect for most chemicals found in the water treatment process.

In addition to Chem Proline® Advanced PE pipe, fittings and valves, we also feature a wide array of accessory components including, gauge guards, degassing valves, check valves, back pressure relief valves and pulsation dampeners all available with thread-free connections.
