Description

TECHNICAL FIELD [0001] The present invention relates to an ultrasonic pigging system,

The present invention relates to a pigging system, and more particularly, to an ultrasonic pigging system and method for performing internal cleaning of various pipelines by using ultrasonic waves and confirming the position of the pigments with a vibration sensor.

In general, pigs have been developed for the purpose of removing scale attached to the inside of a pipe and the foreign matter contained in the inside of the pipe, that is, for cleaning the pipe. Therefore, pigs have been mainly used for maintenance of existing pipes.

Recently, however, pigg has been widely used not only for cleaning existing pipes but also for cleaning work before use of new pipes. In addition, it is now also used for on-line pigging systems where piggies are simply removed from the cleaning role and coated on the inner wall of the pipe, or simultaneously transport different types of fluids through a single pipe. In addition, intelligent pigs equipped with advanced computer equipment in large pigs can perform complicated exploration work such as corrosion degree and thickness of piping as well as monitoring the overall condition of the piping. Diagnosis, and so on. Therefore, in piping facilities for gas pipes, oil pipelines, and other fluids, pigs are now recognized as essential components for the maintenance of piping.

On the other hand, the pipework is used to stop the piping for its own use and to be used only for cleaning, or in the course of using the piping for its own use. In the case of the former, off-line pigging pigging, and the latter is called on-line pigging. A typical example of on-line pigging is a technique of transferring various kinds of fluids from pigments to one another in a state where they are separated from each other by using pigs. It produces various kinds of fluids having different compositions, such as a lubricant factory, The online piggybacking method is crucial when it is necessary to transfer them to a single piping.

However, in the case of the prior art, there is a problem that the deposited layer is not removed cleanly or the operation is stopped for removing the deposit layer, and there is a problem that it is difficult to detect the position of the pig.
