Title:
APPARATUS FOR PREVENTING CORROSION INSIDE STEEL PIPE BY USING ELECTROMAGNETIC FIELD
Document Type and Number:
WIPO Patent Application WO/2019/231041
Kind Code:
A1
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 spirally surround 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 first coil; 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.
