Abstract

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 their magnetic state, which allows shortening repair time by means of executing demagnetization in parallel with other operation procedures.
