Introduction to EMT Blue Disc Cleaning Pig

A pig tracker is an essential tool for monitoring the movement and status of pipeline pigs during their operation.

It consists of two main components. One is an electronic transmitter mounted on the pig. The other is an electronic receiver situated on the ground. For example, the EMT Blue Disc Cleaning Pig features an advanced electronic transmitter. This transmitter continuously emits electromagnetic signals as it travels through the pipeline.

These signals transmit at regular intervals. They can penetrate through the pipe wall and the surrounding soil layer. This ensures reliable communication. The receiver probe captures these electromagnetic signals and processes them. This allows operators to monitor the pig’s operational status in real-time.

Through this signal transmission, operators gain immediate insights into the pig’s performance. They can determine whether it effectively cleans the pipeline. They can also identify any issues that need addressing. Additionally, if a pig becomes stuck, the system enables accurate localization within the pipeline. This facilitates timely interventions to resolve the issue.

This technology enhances pipeline maintenance by providing critical data on the cleaning process. It allows for proactive management and reduces potential downtime. Overall, integrating a pig tracker like the EMT Blue Disc Cleaning Pig improves operational efficiency, safety, and reliability in pipeline management.

Pig Tracking System

A pig tracking system is an advanced device designed for intelligent pipeline monitoring. This system comprises several key components: an electronic transmitter, an electronic receiver, an electronic through indicator, and a pipeline through indicator.

Electronic Transmitter: This includes a host composed of an LC oscillator and a pulse signal generator (modulator), along with a high-energy, non-rechargeable lithium battery (customizable options are available). It is mounted on the pig and operates in sync with its movement.

Electronic Receiver: This component consists of a host, a probe, and a monitoring headset. It is a portable device used by ground personnel to detect signals transmitted by the pig.

Electronic Through Indicator
This unit includes one host and two probes. The electronic through indicator functions as a portable mobile device that personnel strategically place at landmark positions on the ground for effective monitoring.

Pipeline Through Indicator
The pipeline through indicator consists of a head and a sensor, and installers position it along the pipeline at specific points, such as the ball cylinder, ball receiving cylinder, and designated monitoring locations. Technicians connect it using a clamp system, and it features external power supply capabilities as well as remote transmission functionality.

Together, these components facilitate real-time tracking and monitoring of pigs within pipelines, enhancing operational efficiency and safety.

Tracking Device Working Principle

Tracking Device Working Principle
The transmitter’s source emits alternating electromagnetic signals through an inductor coil. By doing so, it utilizes the strong penetration capability of ultra-low frequency electromagnetic waves to transmit energy into the ground space. Meanwhile, the receiver captures the emitted electromagnetic wave signals via a probe, enabling effective tracking.

How to Use the Electronic Transmitter
The specific steps for operating the transmitter are as follows:

First, open the back cover using a special wrench by rotating it counterclockwise.
Next, connect the two parts of the switch, ensuring the self-locking device is oriented correctly. Keep in mind that incorrect electrode connections may damage the equipment.
Then, conduct a signal reception test with the receiver. If the receiver detects the signal normally, proceed to the next step.
After that, inspect the sealing ring of the end cap to ensure it is intact. If you find any damage, replace it immediately.
Following this, tighten the back cover by rotating it clockwise and attach the transmitter to the pig. For pigs with a diameter below Φ325, install the transmitter within the pig’s skeleton. We recommend using a stainless steel skeleton to minimize signal shielding.
Once you have done this, perform another signal reception test with the receiver. If the signal is received normally, the pig can be placed in the service cylinder and pushed to the reducer to begin pipeline cleaning.
Finally, after completing the pigging task, open the back cover and pull out the plug to disconnect the power supply.
