แฟล็ก Flangge เมาท์เซ็นสัญญา Pig Engineering Pig แบบถอดออกได้

Removable Pig Signaller used in pipeline pigging operations are generally installed on the incoming and outgoing pipelines of long-distance pipelines. After long-term use, the ball indicator will have equipment corrosion and aging of the rubber seal ring of the movement. This will lead to different degrees of oil and gas leakage, indicator action failure, and other faults. The current solution is to shut down the pipeline. The operator will relieve and empty the oil and gas in the pipeline. And then repairing and replacing the indicator movement.

In order to solve the problems of difficult maintenance and replacement of Removable Pig Signaller. High shutdown cost, and high safety risk. By analyzing and studying the ball indicator, we have developed a pressure disassembly tool for the ball indicator. The tool can maintain and replace the ball indicator movement when the long-distance pipeline is under pressure. The practical application shows that the tool can reduce the abnormal shutdown time of long-distance pipelines. It is easy to operate, safe and reliable, and can reduce the maintenance cost of enterprises. Therefore, it has broad application prospects

Features of Removable Pig Signaller:

1. It is suitable for pipes above 2 ".
2. For flange connection, the design pressure is from ANSI 150# to 2500#. The maximum design pressure of nozzle welding is up to 10000psi (69mpa).
3. The working temperature range is -20 ºC ~120 ºC, and special seals are used when the working temperature exceeds this range.
4. The trigger mechanism does not use the dynamic seal. Which can prevent leakage and ensure trigger flexibility. (except for the low-cost nozzle connection pop-up ball passing indicator and digital display ball passing indicator).
5. It is easy to install, requires little maintenance, and has strong durability (verified by ten years).
6. The insertion depth can be customized according to customer needs.

Production Purpose:

Removable Pig Signaller is a piece of the necessary equipment in the long-distance pipeline ball descaling process. It can accurately show whether the pig has passed a predetermined place. And assist in the successful completion of pigging. At present, the ball indicators used at home and abroad can basically meet the requirements of pigging and cleaning. But their maintenance and repair are more troublesome. Most of them require pipeline pressure relief and shutdown, and the economic losses are immeasurable. Based on the above reasons, the company has also developed a ball indicator that can be disassembled under pressure without pipeline pressure relief and shutdown.

Its main parts are made of stainless steel, which is acid and alkali resistant and corrosion resistant. This ball indicator is in the form of mechanical contact. So its action is sensitive and reliable. It can position and regularly transmit the passage of pigging objects in the pipeline through the mechanical structure. It has many advantages, such as simple structure, explosion-proof, intuitive and reliable indication. And it can be disassembled under pressure. The instructions are helpful for you to install, use and properly maintain the ball indicator. Therefore, please read the instructions carefully before installing and using this indicator.
