Pig refers to the equipment that can clean the pipeline. As we all know, the pipeline needs to be cleaned regularly in order to keep it unblocked. However, some people do not pay much attention to pigging. Pigging is usually remembered when serious problems occur. However, it is too late at this time, so we need to pay attention to pigging at ordinary times. This has many benefits. The necessity of using pigs is introduced in detail below.

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.

Magnetic particle testing (MT) is one of the oldest and most reliable nondestructive testing technologies. But few people can fully recognize it. In the field of material testing, people usually think that it is an unattractive but essential testing method. So we usually use it to inspect the pig signaller with welded base or other products.

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.

1. Applicable temperature: – 40 ~ 85 “C. 2. Suitable for transmission pipes of all materials

EMT new design high pressure intrusive type pig signaler could work under the greatest pressure of 3770Psi. The intrusive type pig signaler could indicate the passage of pipeline pigs more accurate when the pipeline pigs touch the trigger of the pig signaler.
