In Shenyang EMT Piping Technology Co., Ltd,, on Dec. 6, the staff sang the familiar birthday song to send sincere wishes to several "birthday stars" wearing birthday hats.

This is China Shenyang EMT Piping Technology Co., Ltd, We are a professional manufacturer of pipeline cleaning 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.

The main component of Corrosion Probes is a metal sensing element. The element is destroyed after the probe is corroded by the medium in the environment in which it is used. Then its geometry changes. Using Ohm’s law, the resistance of a metal element is related to its geometric size. Finally, by measuring the resistance change of the element before and after corrosion. Combining the time monitoring of the two monitoring readings, we can calculate the corrosion rate (mm/a).

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

In pipeline pigging, it is very necessary to understand the classification of pipes. Because only by understanding the performance and material of different pipes. So we can choose the type of pig according to this.

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.
