Gas Leak Detection for Gas Transmission Pipelines

Gas transmission pipelines operate under high pressure and often traverse large, remote areas. Even small leaks can escalate rapidly, leading to fire, explosions, supply interruptions, or environmental impacts.

ProDetec designs gas detection monitors specifically for pipeline environments, addressing risks such as:

  • Methane leaks from flanges, valves, and mechanical joints
  • Equipment failure at compressor and metering stations
  • Accumulation of gas in enclosed or partially enclosed structures
  • Undetected releases in open or ventilated areas

Our solutions support continuous monitoring of critical assets, providing early warning and enabling fast intervention before incidents occur.

Types of Gas Detection Technology We Deploy in Australia

Selecting the correct detection technology is critical to system reliability and compliance. ProDetec engineers solutions using proven technologies matched to gas type, environment, and risk profile.

Infrared Gas Detection

Infrared detection is widely used for methane gas monitoring & detection in gas transmission due to its stability, resistance to poisoning, and low maintenance requirements.

Ultrasonic Gas Leak Detection

Ultrasonic detectors identify the sound generated by high-pressure gas releases, making them suitable for open, windy environments.

Catalytic Gas Detection

Catalytic sensors detect flammable gases through combustion-based measurement. While effective, they require oxygen and more frequent maintenance.

Open-Path Laser Detection

Laser diode open-path systems provide wide-area coverage and are ideal for perimeter gas monitoring along pipeline corridors and site boundaries. ProDetec provides clear, technically grounded comparisons to ensure the right technology is applied in the right location.

Environmental Compliance & Emissions Reduction

Methane is a potent greenhouse gas, and reducing fugitive emissions is an increasing regulatory and corporate priority in Australia. ProDetec’s gas leak detection solutions support environmental compliance by:

  • Identifying leaks early
  • Supporting emissions reporting and reduction initiatives
  • Improving asset integrity and efficiency

Effective gas detection plays a direct role in meeting Australia’s environmental commitments while improving operational performance.

Continuous Monitoring vs Periodic Surveys

ProDetec supports both continuous monitoring and periodic inspection approaches, depending on the asset and risk profile.

  • Continuous monitoring using fixed systems provides real-time protection for high-risk or critical assets.
  • Periodic surveys using portable devices support maintenance and inspection activities, but are not a substitute for fixed detection in hazardous environments.

We help operators determine the appropriate balance to meet safety, compliance, and operational objectives.

integration

Integration with Control & Emergency Systems

Effective gas detection is only valuable when it is connected to appropriate response mechanisms. ProDetec integrates gas detection systems with:

  • SCADA and PLC platforms
  • Alarm and notification systems
  • Emergency shutdown (ESD) systems
  • Ventilation and mitigation controls

This integration ensures gas leaks trigger timely, automated responses that reduce escalation risk and protect both people and assets.

Frequently Asked
Questions

How is a gas detector calibrated?

Calibration involves exposing the sensor to a known concentration of gas, verifying its response, and adjusting the detector to ensure accurate readings. ProDetec uses NIST/NATA-traceable calibration gas and certified procedures for all devices.

Can I calibrate my own gas detector?

While some bump tests can be performed in-house, full gas detector calibration requires certified gas, technical expertise, and proper documentation to ensure compliance. ProDetec provides both on-site and in-house service solutions.

How much does gas detector calibration cost?

While some bump tests can be performed in-house, full gas detector calibration requires certified gas, technical expertise, and proper documentation to ensure compliance. ProDetec provides both on-site and in-house service solutions.

What is the turnaround time?

Turnaround depends on the number of detectors and service type. Routine gas monitor calibration is typically completed within 24-48 hours for portable detectors, with fixed system calibrations scheduled to minimise downtime.

Do you provide calibration certificates?

Yes. Every gas detectors calibration service includes a traceable certificate of calibration for regulatory compliance and internal record-keeping.
