Oil is extracted from the underground to the ground and transported to a large refinery to refine the crude oil into the raw materials and the oil which we need. In the process of transporting crude oil, the main transportation tools are divided into two kinds. One is to transport crude oil by vehicle mounted oil tank truck. In this case, the cost is very high. Generally, crude oil is transported by oil pipeline.

The Non-intrusive Pig Signal Indicator by EMT is a cutting-edge device designed to enhance the efficiency and accuracy of pipeline monitoring. As a leading provider of pipeline inspection solutions, EMT has developed this state-of-the-art indicator to address the challenges faced in detecting and tracking pigs during oil, gas, water, and other transmission pipeline operations. With its advanced features and reliable performance, the Pig Signal Indicator revolutionizes the way pipeline inspections are conducted, ensuring seamless pig passage detection.

Recently, EMT formally joined PPSA and became its full member. In the future, we will continue to deepen exchanges and cooperation within the industry with more peers, continue to explore and innovate in the production industry of pipe fittings, expand market space, and serve more customers.

In the pipeline pigging operation, we usually install the Pipeline Pig Signaller on the incoming and outgoing pipelines of long-distance pipelines. Because after long-term use, after passing the ball indicator. This product will cause equipment corrosion and aging of the rubber sealing ring of the movement. This will lead to different degrees of oil and gas leakage. There are also failures such as indicator action failure. At present, our solution is to shut down the pipeline. Then the operator will release and empty the oil and gas in the pipeline. Then the maintenance personnel shall repair and replace the indicator movement.

Working principle The end of the extension sleeve is provided with a striker which can be triggered in both directions. It passes through the connecting pipe of DN50 and probes into the interior of the pipe near the pipe wall. When the pig passes, it will move the striker. It transmits the action to the instrument button through the connecting rod in the sealing shaft sleeve. Then it triggers the operation of the display instrument.
