Apparatus for preventing corrosion inside steel pipe by using electromagnetic field

Abstract

The present invention provides an apparatus for preventing corrosion inside a steel pipe by using an electromagnetic field comprising: a tubular body having a flange part formed on both ends to be coupled to a water pipe, and having a flow path formed therein to supply tap water flowing through one side of the water pipe to the other side of the water pipe; a first coil disposed so as to spirallysurround the tubular body on the outside of the tubular body; a second coil disposed so as to spirally surround the first coil on the outside of the first coil while being spaced apart from the firstcoil; a power supply for supplying current to the first and second coils to form an electromagnetic field in the tubular body, wherein the tubular body is made of stainless steel so as to reinforce the intensity of the electromagnetic field formed by the first and second coils.

Description

technical field [0001] The present invention relates to a device for preventing internal corrosion of a steel pipe by using an electromagnetic field. More specifically, it relates to a device for preventing internal corrosion of a steel pipe by using an electromagnetic field. A first coil and a second coil are arranged on the outside of the tube-shaped main body in a double structure, and It is installed to be connected to a water supply pipe for running water to form an electromagnetic field and prevent corrosion inside the steel pipe. The pipe-shaped main body is made of stainless steel, and flanges for coupling with the pipe are formed at both ends. Background technique [0002] Usually, with the passage of time, the steel pipe used as the water supply pipe is corroded due to various corrosion-inducing substances contained in the water. The corrosion of such a water supply pipe not only makes the water quality of the tap water poor, but also makes the water supply The rig...

[0004] However, the fact is that, as far as the method of using the corrosion inhibitor is concerned, since the antirust agent must flow into the interior of the pipeline, it cannot be applied to the anticorrosion of the water supply pipeline. As far as the water quality factor control method is concerned, in order to regulate corrosion One of the pH conditions is to invest in slaked lime series, but as a way to improve the corrosion of tap water, its effect has not been seen in wide-area water supply pipelines.
