A 20″ pipeline in the northeast is magnetized to levels around 300 gauss. The cut easily holds a welding rod. The welders have enough work to do, so going through the effor to demag the pipe with welding leads does not fit into the schedule. The operator and contractors on site used the IDMAG Pipeline Demagnetizer to de-mag the pipe.
The IDMAG Pipeline Demagnetizer is easy to set up and simple to use. On a 20″ pipe like this, you should have the equipment installed and the pipe demagged within 15 minutes. It’s the right tool for the job.
