Once the pig/ILI tools are stuck in a certain position and cannot be positioned in time, it will affect the normal oil and gas transportation, and even endanger the safety of the pipeline. Therefore, the tracking and positioning of the pig is an extremely important content in cleaning operation.
Shenglong will equip pigs/ ILI tools with transmitter, which is conducive to timely and accurate position of the pig/ /ILI tools in running. In case of stuck, the receiver can accurately determine the position of the pig/ ILI tools, which can reduce the risk of cleaning / inspection and improve the efficiency.

Transmitter installation position

The transmitter installed on the pig body continuously launches out low frequency signals that can penetrate the pipe wall. When tools running in the pipeline, the ground tracking personnel use the receiver at the preset tracking points to receive the signal from the transmitter at a predetermined time, so as to inspect the operation status and position of the pig running in the pipeline. When the pig / ILI tools get stuck, the receiver can be used to judge the position of the pig accurately.
