Demagnetization of magnetically influenced pipeline

摘要

The disclosed subject matter relates to a pipe demagnetizing device. More specifically, more specifically, when the magnetic force is formed in the pipe by the intelligent pig work and other causes, the magnetic force formed in the pipe for measuring the magnetic force removed as a prerequisite in the plumbing work is measured and The present invention relates to a pipe demagnetization device for canceling or removing the magnetic force of a pipe by generating a magnetic force opposite to a magnetic force generated in a pipe by flowing a direct current electricity. Pipe magnetic removal device according to the present invention can measure the magnetic force direction and the magnetic strength of the pipe without a separate Gaussian for measuring the magnetic force, the installation time is reduced by inserting the pipe into the coil wound beforehand, When welding using this device, the work can be performed while removing the magnetic force formed in the pipe very effectively, thereby reducing the welding defect rate and providing the effect of greatly improving the welding efficiency, quality, and safety of the equipment. In addition, since it is a high voltage and low current type, there is no fear of burn or explosion due to heat generated when a large current flows, and it automatically adjusts the magnetic force when using the automatic mode. Provide effect.
