7. Applications and Advantages

01 Applications in Various Industries

• Oil and Gas: In the oil and gas industry, maintaining pipeline integrity and efficiency is paramount. The EMT Non-Intrusive Pig Signaller is extensively used to detect the presence and passage of cleaning, inspection, or separation pigs through pipelines. This ensures that pipelines remain free from deposits and blockages, which can affect flow rates and lead to increased operational costs or environmental risks.
• Chemical Processing: In chemical processing plants, pipelines transport a variety of reactive and non-reactive substances. Regular pigging is necessary to prevent cross-contamination, build-up of residues, and potential blockages. The EMT Non-Intrusive Pig Signaller assists in scheduling maintenance pigging operations, thus ensuring product purity and process efficiency.
• Water Treatment: For water treatment facilities, ensuring that pipelines are free from obstructions and contaminants is essential for maintaining water quality. The signaller detects cleaning pigs used to remove sediments and other deposits from inside the pipes, aiding in the maintenance of the infrastructure and compliance with health regulations.
• Marine and Offshore: In marine and offshore environments, pipelines often transport crude oil or natural gas under harsh conditions. The signaller is crucial for monitoring pigging operations in these scenarios, helping to prevent pipeline corrosion and fouling which are common in saline environments.

02 Technical Advantages

• Non-Intrusive Technology: The device’s non-intrusive design is one of its most significant advantages. By mounting externally, it avoids compromising the pipeline’s structural integrity. This design choice significantly reduces the risk of leaks or bursts, which can be catastrophic, especially in high-pressure environments.
• Versatility in Detection: The ability to detect a wide range of pig types, including foam, metal-bodied, polyurethane, spheres, and mandrel pigs, makes this signaller highly versatile. This feature ensures that operators can use the device across various pigging applications without needing specific adaptations or multiple devices.
• Durability and Reliability: Engineered to withstand extreme conditions such as high pressures and temperatures, corrosive environments, and mechanical stresses, the signaller promises longevity and reliability. This durability translates into lower maintenance costs and fewer replacements over the pipeline’s lifespan.
• Enhanced Safety Features: With the option for visual and electrical signaling, operators can receive immediate updates on pigging operations. This real-time monitoring capability enhances operational safety by allowing timely interventions if a pig becomes stuck or lost, preventing potential damage or accidents.
• Cost-Effectiveness: By minimizing the need for frequent pipeline shutdowns and manual inspections, the EMT Non-Intrusive Pig Signaller reduces operational costs. Its efficient monitoring capabilities allow for better planning and execution of maintenance schedules, which in turn extends the lifespan of pipeline infrastructure.
• Ease of Installation: The flexibility to be installed on various flange sizes and compatibility with existing signaller bosses ensures that integration into current systems is straightforward, avoiding costly modifications.
