Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a corrosion inhibitor injection apparatus for piping,

The present invention relates to an apparatus for injecting corrosion inhibitor for piping.

Pipes installed in vessels and offshore plants are highly likely to corrode because they transport various chemical substances. Therefore, a corrosion inhibitor for preventing corrosion can be injected into such a pipe.

The corrosion inhibitor can maximize the corrosion inhibition effect when it is uniformly mixed with the fluid transported along the piping, and to ensure that the corrosion inhibitor is uniformly mixed with the fluid, a mixing section of sufficient length along the pipeline must be secured. However, it sometimes happens that it is difficult to secure a mixing section of a sufficient length for the piping design as in the case where the piping is installed in a narrow space. Accordingly, even if it is difficult to secure a mixing section having a sufficient length, it is necessary to take various measures to uniformly mix the corrosion inhibitor injected into the pipe into the fluid.

1, a piping corrosion inhibitor injection device 20 and a sampling device 30 according to an embodiment of the present invention are respectively installed in a first opening 11 and a second opening 13 of a pipe 10 Can be installed.

A first opening 11 and a second opening 13 spaced apart from each other along the fluid moving direction are formed on one side of the pipe 20 in a direction parallel to the flow direction of the pipe 10, May be formed through the side wall. The second opening 13 may be disposed on the downstream side of the first opening 11 along the fluid moving direction.

The corrosion inhibitor injector 20 may inject corrosion inhibitor into the interior of the pipe 10 to prevent corrosion of the pipe 10 by the fluid moving along the pipe 10. [

The sampling device 30 can be inserted into the piping 10 through the second opening 13 to collect a part of the fluid mixture in which the fluid and the corrosion inhibitor are mixed in the piping 10. By analyzing the fluid mixture sampled by the sampling device 30, it can be determined whether the corrosion inhibitor is uniformly mixed with the fluid. To this end, the second opening 13 may be formed at the end of the mixing section A where uniform mixing between the fluid and the corrosion inhibitor is to be completed. On the other hand, the pipe 10 can be made intuitive in the mixing section (A).
