Containment Pipe System


ENI-GARD™ is the Premier Engineered Series double containment pipe system designed to protect against any leakage from expensive environmental accidents and exposed hazardous chemicals or materials caused by corrosive leaks from the primary carrier piping.

The ENI-GARD system consists of a carrier pipe, a containment pipe coated with urethane or a fiberglass-reinforced polymer (FRP) outer jacket, and an optional PermAlert® cable leak detection system. This innovative system not only protects the environment from contamination but also ensures compliance with all federal and state-level regulations and the safety of protecting people’s health.
