Gas Tracer Injection Systems
Specialized equipment for injecting hydrogen-nitrogen tracer gas into isolated pipe sections for leak detection.
How Gas Tracer Injection Systems Works
Gas tracer injection systems are the specialized equipment used to introduce tracer gas into pipes for leak detection. The system consists of a pressure-regulated gas cylinder containing the 95% nitrogen / 5% hydrogen mixture, a pressure regulator and gauge for controlling injection pressure, a flow meter to measure gas volume injected, hoses and connectors for attaching to the pipe system, and safety equipment including check valves and pressure relief devices. The injection process involves: isolating the pipe section, draining the water if necessary (for pressurized systems), connecting the injection system to an available fitting (bleeder valve, drain port, test tee), and slowly introducing the gas mixture to the system pressure. The total gas volume required depends on the pipe diameter and length being tested.
Applications in BC
- Underground pipe leak detection with tracer gas
- Low-pressure and non-pressurized system testing
- Geothermal ground loop leak location
- Residential service line leak detection on plastic pipes
- Fire suppression system integrity testing
Advantages
- Controlled, safe injection of tracer gas
- Precise pressure regulation for different pipe types
- Flow metering for gas volume calculation
- Multiple connection options for various pipe fittings
- Safety-certified components for field use
Limitations
- Bottled gas supply is consumable and must be replenished
- Injection setup time adds to service duration
- Not suitable for pipes that cannot be isolated
- Higher gas cost for large-diameter pipes
