Water Seal
Reliable Flashback Prevention and Pressure Isolation with Engineered Water Seals

Overview
CRA Water Seals are engineered flare safety devices designed to prevent flame flashback and provide pressure isolation between the process header and flare stack. By maintaining a liquid barrier within the seal vessel, the system blocks flame propagation while allowing controlled gas flow to the flare. Designed for continuous industrial service, CRA water seals ensure safe flare operation during normal, upset, and emergency conditions.
Key Benefits
Liquid seal barrier prevents flame propagation from the flare stack into process piping.
Isolates upstream equipment from flare backpressure and pressure fluctuations.
Operates without moving parts, ensuring reliable performance with minimal maintenance.
Maintains safe system separation during normal and emergency flare conditions.
Designed for high-temperature, corrosive, and variable flare gas environments.
The CRA Edge
Deep expertise in flare system safety and protection devices.
Hydraulically sized water seals matched to flare system duty.
Designed in line with accepted flare safety practices.
Compatible with CRA and third-party flare systems.
