HGXC series pipeline demagnetizer Input Voltage 380V blue body for pipeline construction

INTRODUCTION

After cutting off the pipeline buried long-time in underground, a relatively strong magnetic field will be generated at the pipe orifice, resulting in the inability to weld the pipeline. Also, it will lead to great impact on the welding, testing and other processes. HGXC series pipeline demagnetizer is to wind the cable at the orifice. According to the principle of electromagnetic induction, a magnetic field will be temporarily formed at the orifice after power on. Through adjustment, the direction of the magnetic field is opposite to that of the pipeline magnetic field, so as to temporarily offset the original magnetic field and make the welding proceed smoothly.

During the construction of pipelines, it is crucial to ensure that the pipes are free from residual magnetism. This is because residual magnetism can affect the accuracy of magnetic-based inspection techniques, such as magnetic particle testing or magnetic flux leakage inspection, which are commonly used to detect defects or vulnerabilities in the pipes.

By using a pipe demagnetizer, the residual magnetism in the pipes can be effectively eliminated or reduced. This ensures that subsequent inspection processes are accurate and reliable, allowing for the identification of any potential flaws or weaknesses in the pipeline. Furthermore, demagnetized pipes are less likely to attract or retain ferromagnetic particles, which could otherwise lead to corrosion or other issues in the long term.

Overall, the use of pipe demagnetizers in pipeline construction plays a vital role in maintaining the integrity and quality of the pipeline system. It helps to ensure accurate inspections, minimize potential problems caused by residual magnetism, and promote the longevity and reliability of the constructed pipelines.
