Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a leakage monitoring system,

The present invention relates to a leakage pressure information monitoring system for a flange connection. More particularly, the present invention relates to a leakage pressure information monitoring system capable of promptly responding to a leakage accident through flange connection portions by acquiring and monitoring in real time the leakage pressure information of flange connection portions provided in a very large number of pipelines installed in an industrial plant site .

In general, industrial plants such as petrochemical plants are equipped with a large number of pipes through which fluids such as gas flow. These pipes are connected through a flange to form a pipeline, which must be tight to maintain the functionality of the industrial plant. Since leakage through pipelines through flammable gas can lead to very dangerous situations, the status of flange connections and pressure checks on pipelines are performed periodically at industrial plant sites.

A conventional method of checking the pressure on a pipeline including flange connections will be described as follows.

First, after removing the flammable gas filled in the pipeline, a process of filling the pipeline with a non-flammable gas such as nitrogen is performed and the interior of the pipeline is pressurized to a level higher than the normal operating pressure.

If the pressure inside the pipeline does not fall below the supply pressure, the condition of the flange connections can be judged to be normal.

Conversely, if the pressure inside the pipeline drops relative to the supply pressure, it can be determined that leakage has occurred through at least one of the flange connections. In this case, it is necessary to repeat the above-described pressure check process after performing a job of finding a leak at a certain flange connection and repairing a flange connection where leakage occurs.

According to the conventional pressure checking method of the flange connection portion, there are the following problems.

First, since the leakage pressure inspection work of the flange connection portion is performed manually by the field worker in accordance with the predetermined work cycle, the leakage pressure information of the flange connection portion can not be obtained in real time, There is a problem that it can not be coped with quickly.

Second, in order to find out where the leakage occurred from the many flange connection parts of the pipeline to be inspected, a skilled worker performs leakage detection confirmation work on all flange connection parts provided in the pipeline by using a separate leak detection device Therefore, there is a problem in that the efficiency in terms of time, cost, and manpower is very poor.

Third, leakage pressure checks require the process of filling and unplugging the non-flammable gas to be repeated, which results in significant costs due to the consumed non-flammable gas and takes a long time for non-flammable gas filling and removal There is a problem.

The gasket identification information is information for identifying the gasket 130 corresponding to the sensor identification information. As described above, the sensor identification information is information for identifying the sensor main body module 210 constituting the pressure sensing unit 20. [ The pressure sensing part 20 senses the leakage pressure of one flange connection part 10 on which the gasket 130 is mounted so that the gasket 130 and the pressure sensing part 20 correspond to each other, The controller 40 can manage the status of the entire gasket 130 through the gasket identification information corresponding to the sensor identification information.

The state analysis module 440 compares the leakage pressure information received via the server side communication module 410 with the state analysis basic information stored in the information storage module 420 to analyze the state of the flange connector 10, .

For example, the state analysis information generated by the state analysis module 440 may include leakage state step information and replacement recommendation information.

The leakage state step information is generated by comparing the leakage pressure information received from the pressure sensing unit 20 with the maximum leakage allowable amount information stored in the information storage module 420 by the state analysis module 440 Information. The manager located at the remote location can grasp the degree of the leakage situation and determine the priority of the maintenance work through the leakage situation phase information.

The replacement recommendation information is generated when the state analysis module 440 compares the current time information with the use start time information to generate cumulative use time information of the gasket 130 and generates when the cumulative use time information exceeds the recommended use time information Information. This replacement recommendation information can be used as a reference for the administrator to determine when to replace the part.

The server side control module 450 controls the operation of the server side communication module 410, the information storage module 420, the information display module 430 and the status analysis module 440.
