The complete solution for hot corrosive fluids

Corzan is a complete pipework system for handling hot, corrosive fluids.​

Corzan offers excellent performance levels in highly aggressive industrial conditions. The fully-matched system of pipes, fittings and valves is designed to convey hot acids and alkalis under pressure at elevated temperatures.

The smooth surface of Corzan is corrosion resistant which makes it superior to metal pipework alternatives which can become prone to corrosion resulting in process leaks, flow restrictions and ultimately premature system failure.

Corzan is also suitable for installation in corrosive atmospheres where external corrosion may be prevalent within traditional materials.
