Research into methods of pipe end demagnetization under main pipeline repair

Efficiency of pipe end demagnetization methods is experimentally investigated to avoid arc magnetism at repair welding jobs on main pipelines. It is found that multi-polar biased static and dynamic demagnetization provides an acceptable level of magnetic flux density on pipe ends and stability of th...
