Demag of 42″ Pipeline

A valve was being installed on a 42″ pipeline.  The line had been pigged in the past and the contractor knew that the pipe was going to be heavily magnetized and would need to be demagnetized prior to welding.  Using a welder and wrapping the welding leads would not be enough to demag this pipe.

The IDMAG System was used to successfully demag the pipe and allow the welders to do their job.


The IDMAG System is available to rent and on-site demag services are also available.
