Pig launcher and receiver is a general term for cleaning, receiving, or sending pigging equipment for oil, gas, and other pipelines. The two ends of the installed pipeline are mainly composed of a cylinder, quick opening blind plate, reducer, support, short pipe, and other parts. It has the advantages of simple structure, fast switching, good sealing performance, simple operation, good corrosion resistance, safety, and reliability. Its design and manufacture refer to GB150 steel pressure vessels.

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).

Pigs for Pipeline Cleaning Pigs are supporting equipment for pipeline cleaning. Pigs for Pipeline Cleaning are driven by gas, liquid, or pipeline transmission medium. It can carry other auxiliary equipment to complete various complex pipeline operations. Without pigging technology, it is impossible to carry out pipeline construction and operation. Only pigs can accomplish a lot of work economically. Therefore, pipeline technology and pigging technology are inseparable.

The Working Process of The Pig is As Follows: Stage 1: Product transmission. Stage 2: The pig is pushed into the product pipeline by compressed air. Stage 3: Pig return.

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

Pipeline damage Pipeline damage is usually the first indication of corrosion problems. However, in many cases. Such signs of pipeline damage will obviously exist for months or years. It’s just that people have been ignoring it. This damage may be minor (in the form of pinhole leakage). It can also be catastrophic. Because whether the water quality is damaged or the pipeline is replaced, it will bring significant economic losses.

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.
