ULTRADEMAG
The ULTRADEMAG equipment is designed for full-length demagnetization of pipes by a combined alternating decaying external magnetic field down to a level of 10–15 G (1.0–1.5 mT).

EQUIPMENT FEATURES
- Demagnetization of pipes along their entire length, including the end sections, down to 10–15 G (gauss);
- Automatic measurement of the initial magnetization at the unit entry and of the residual magnetization at the exit;
- Automatic selection of the demagnetization mode depending on the initial magnetization of the pipe;
- Generation of a demagnetization report and residual magnetization plots along the entire pipe length, with automatic archiving, storage and transfer of these data to the higher-level information network.
