Mode of Operation
The system is calibrated on a standard at the beginning of the job. The magnetizing coil is placed over the end of the pipe. The buggy drive and head are placed on top of the pipe and the mag coil is placed on the buggy drive. The air jacks lift the pipe so the coil & buggy will clear the pipe racks. The electronics operator then powers the buggy down the pipe and starts the thermal printer (or optional DAQTech III™ computer data acquisition system) and observes the data. When the buggy reaches the other end of the pipe, the jacks lower the pipe to the racks, the buggy and coil are removed and placed on the next pipe. The process is then repeated in the opposite direction.
