Introduction

The EMT Intrusive Type Pig Signaller features a robust design incorporating a mechanical trigger mechanism within the pipeline wall. Operators install this device directly into the pipeline through a specialized fitting. As the pig moves along, it physically engages the trigger, initiating the signal process.

Upon activation, this signaller transmits visual and electrical signals to a remote monitoring system, confirming the pig’s passage. Operators then need to reset the device manually or automatically for the next use. This functionality ensures continuous and reliable monitoring of pipeline cleaning or inspection activities.

The EMT Intrusive Type Pig Signaller is highly effective for real-time tracking in diverse pipeline environments. Its adjustable features, such as insert depth and different materials for internal parts, cater to specific operational needs. With its explosion-proof certification and high ingress protection rating, it ensures durability and reliability even in harsh conditions. This adaptability and robustness make it a preferred choice for critical pipeline operations.

Parameters

Advantages

Pig signallers, particularly the intrusive type, offer numerous advantages that significantly enhance pipeline maintenance and monitoring operations:

High Reliability: By making direct contact with the pig, intrusive pig signallers provide a highly reliable detection method. They confirm the pig’s exact location as it passes, reducing uncertainties that may arise with non-intrusive methods. This relies on magnetic or acoustic detection.
Versatility: Intrusive pig signallers are compatible with a wide range of pipeline types and pig designs. Whether dealing with foam pigs used for cleaning, batching pigs for separating different product batches, or intelligent pigs for detailed inspections, these signallers can efficiently handle all.
Immediate Feedback: They provide immediate visual and/or electronic feedback when a pig passes the designated point. This instant confirmation is crucial for operational control rooms to monitor the pig’s progress and ensure the pipeline cleaning or inspection process is proceeding as planned.
Enhanced Pipeline Integrity and Maintenance: The accurate detection of pigs helps in scheduling maintenance and inspection operations more effectively. This capability ensures that pipelines remain in optimal working condition, preventing leaks and failures due to undetected corrosion or blockages.
Operational Safety: By confirming the passage and recovery of all pigs sent through the pipeline, pig signallers help prevent situations where unaccounted-for pigs might cause pressure build-ups or damage to the pipeline. This is particularly critical in maintaining safety standards and preventing accidents.
Cost-Effectiveness: Although they require direct installation into the pipeline, the long-term benefits of reliable pig detection and the prevention of pipeline issues can lead to significant cost savings. These savings come from reduced downtime, fewer operational disruptions, and a lessened need for extensive repairs.
Ease of Use and Maintenance: While some models may require manual resetting, many modern pig signallers are designed for easy use and low maintenance. This ease of handling helps reduce the operational burden and supports quick turnaround times for pipeline operations.

EMT Intrusive Type Pig Signaller Applications

The EMT Intrusive Type Pig Signaller ensures operational assurance by confirming the passage of pigs at critical points. Such confirmation boosts the effectiveness of pigging operations, essential for maintaining pipeline efficiency. It also prevents buildup and potential blockages by verifying the successful transit of cleaning pigs.

For safety monitoring, knowing the location of utility pigs in pipelines carrying hazardous materials is crucial. This knowledge becomes particularly important when pigs are used to separate different product batches. Although the installation of intrusive-type signallers requires a pipeline fitting and might call for shutdowns during maintenance, these devices are indispensable. They provide robust and reliable detection capabilities, which are vital for the safe and efficient transport of oil, gas, and other substances.
