What is a Pig Indicator?
A pig indicator is an essential tool designed to monitor the status of cleaning pigs within pipelines. Initially, as the pig, sphere pig, scraper, and other cleaning tools journey through various sections of the pipe and approach the receiver, the indicators play a crucial role. They can accurately detect the presence of these tools and, consequently, provide timely feedback to the operator. Additionally, the indicators serve as an alert system, informing the operator if a pig becomes lost or gets stuck at the receiver. Thus, by utilizing the information from pig indicators, operators can reliably ascertain whether the cleaning pig has successfully passed through a section of the pipeline or not.
Our popular intrusive indicator series employs a trigger intrusion into the pipeline. Besides, our non-intrusive pig indicators confirm the passage of pigs carrying magnets.

Pig Signaler- 2” Base Welded
Features
The connection is 2” base welded. The material is usually the same as the pipe so that it can weld with the pipe successfully. In addition to its standard 2” base welded connection, the welded base pig indicator offers several other advantages. The material selection, typically matching that of the pipeline, ensures a cohesive and strong weld. This compatibility minimizes potential weak points at the juncture, leading to a more secure and leak-proof operation. Furthermore, a welded base provides enhanced structural integrity, allowing the indicator to withstand high-pressure environments and aggressive substances that may flow through the pipeline. The robust construction also means reduced maintenance and a longer service life, making it a cost-effective choice for long-term pipeline monitoring.

اصل کار
The working principle of the Pig Indicator is based on the interaction between the pig moving through the pipe and the trigger mechanism of the indicator.
The pig indicator should be placed precisely inside the pipe near the wall. It was an intrusive type of pig indicator. When the pig passes, the Pig Indicator trigger is activated to provide the operator with the passage status of the pig.
After the pig has passed, the Pig Indicator’s flag will rotate 90 degrees. Initially, the flag is in a horizontal position, and after triggering the trigger, it moves to an upright position. The change in the direction of the flag provides a visual indication of the pig’s position in the pipe.
Then the operator can determine the location of the cleaning pig based on the position of the flag. This provides a simple and effective way to monitor the progress of the pig through the pipe. Pig Indicator ensures that any cleaning or inspection process goes according to plan.
Once the pig has passed and the monitoring process is complete, the pig indicator’s flag can be reset for the next use. This is done by flipping it counterclockwise and returning it to its original horizontal position, ready for the next pigging.
