Non-Intrusive PIG detection for pipeline integrity and monitoring
What is PIG detection and why do you need a PIG detector?
PIG detection is the process of identifying when a PIG (Pipeline Inspection Gauge) enters, passes through, or arrives at specific points in a pipeline. PIGs are essential tools used for cleaning, inspecting, and maintaining pipelines in both offshore and onshore environments.
A PIG detector - also known as a PIG signaller - is used to confirm the PIG’s movement in real time. This is critical for:
- Verifying successful PIG launch and arrival
- Monitoring PIG passage at key points along the pipeline
- Preparing receiving valves in advance
- Detecting debris pushed ahead during cleaning
- Avoiding lost PIGs and unplanned shutdowns
- Enhancing pipeline integrity and operational safety
- Reducing maintenance costs and downtime
Without a reliable PIG detection system, operators risk delays, safety hazards, and costly interruptions. The ClampOn DSP PIG Detector provides a proven, non-intrusive solution that ensures accurate, real-time PIG detection - improving both safety and efficiency.
