Trigger Options:
- Bi-directional: This feature allows the signaller to detect pig movement in both directions, enhancing its utility in various pipeline configurations.
- Bi-directional feather: Designed for more sensitive operations, this option ensures the detection of lighter or less substantial pig movements, providing greater control and precision.
- Uni-directional: Ideal for straightforward applications where pig movement is expected in only one direction, simplifying operations and maintenance.
Indicator Options:
- Manual Reset Flag: This basic yet reliable indicator provides visual confirmation of pig passage. Operators must manually reset it after each operation, making it straightforward and effective for many standard applications.
- Manual Reset Flag with Electrical Switch Output: This option enhances the manual reset flag by incorporating an electrical switch. It actively integrates with external control systems, enabling automated alerts and logs for enhanced monitoring capabilities.
- Digital Display with Electrical Switch Output: For the most advanced monitoring, this configuration includes a digital display. It actively delivers detailed readings and integrates seamlessly into sophisticated control systems, offering comprehensive management of pipeline operations.
Mounting Types:
- Standard 2″ flange connection: This common mounting option offers a secure and reliable connection, making it suitable for a wide range of pipeline systems.
- 2″ welded nipple: A robust alternative, this mounting type provides a welded connection that ensures a permanent and secure fit, ideal for high-pressure environments.
- 2″ welded base-NPT nipple connection: Combining a welded base with an NPT nipple, this mounting option allows for versatile connections that cater to specific installation requirements and provides exceptional sealing and stability.
Each of these configurations is designed to ensure that the EMT pig indicator can be tailored to meet the specific needs of any pipeline operation, making it a flexible and indispensable tool in pipeline maintenance and monitoring.
Installation Process
A detailed, step-by-step guide facilitates the installation of the EMT pig indicator, ensuring that setup is both straightforward and efficient.
- Threading the O-Let: Begin the installation by carefully threading the O-Let into the designated port on your pipeline. This initial step is crucial for establishing a secure base for the subsequent components.
- Tightening the Plug Body: Once the O-Let is in place, proceed by tightening the plug body. This action ensures that the signaller is firmly attached and stable, which is essential for accurate operation.
- Adjusting Plug Depth: After securing the plug body, adjust the depth to which the plug extends into the pipeline. Proper adjustment is critical for ensuring that the signaller can accurately detect the pig’s passage without impeding its movement.
- Aligning Flag Orientation: Finally, align the flag or indicator to ensure it is clearly visible from the monitoring station. Correct orientation is key to easy and quick visual confirmation during pigging operations.
Packaging
The EMT pig indicator comes securely encased in a lightweight PLYWOOD CASE, meticulously designed to offer multiple benefits:
- Strength: Craftsmen construct the case robustly to endure harsh conditions, effectively protecting the signaller during transportation and storage.
- Insulation: The case features superior insulation properties that actively shield the device from temperature fluctuations and moisture.
- Convenience: The design of the case promotes easy handling and unpacking, simplifying and streamlining the installation process.
Conclusion
To summarize, the Pig Signaller stands out for its exceptional durability, precision, and ease of use. These characteristics make it an invaluable tool in the domain of pipeline maintenance and monitoring.
Final Endorsement:
We wholeheartedly recommend the Pig Indicator as your go-to choice for enhancing the effectiveness and reliability of your pipeline operations. Opting for this signaller ensures that you are equipped with a top-tier tool designed to meet the rigorous demands of modern pipeline maintenance, thus safeguarding your infrastructure and optimizing operational continuity.
