Bobbins ZMBOB

The Zeromag Bobbin enables rapid, repeated deployment of 100m of demag cable for efficient pipe-end degaussing, eliminating the need for manual winding. Used with Zeromag and ZM150, it supports pipe diameters up to 28″ and can be paired in series for larger pipes with high-power setups.

Zeromag ZM100A is used world wide by leading welding companies to overcome arc blow.  The ZM150 degausser in conjunction with the Zeromag ZM100A is used to demagnetize pipe-ends prior to fit-up, or joints post fit up.

Successful degaussing of pipe-ends requires the application of fields large enough to magnetically saturate the steel.  The magnetic field required depends on the type of steel, the number of turns, the current and the ratio of pipe diameter to coil length along the pipe.  Thus there are a variety of conditions that determine whether the saturation magnetic field is reached. Generally for most steels a pipe diameter of less than 28” (0.7m) will be saturated using Zeromag.

Turns can be applied to the pipe end by manually winding the 50 m demag and 50m demag extension cables supplied in the standard package (DKPW).  This is time consuming and not always convenient.  The Zeromag bobbin applies 100m of cable turns repeatedly and rapidly to the pipe-end.

Connection cables are supplied to connect  the bobbin to Zeromag. Bobbins can be supplied for any user defined pipe size.

For degaussing larger pipe ends two bobbins, connected in series, can be used with the high power Zeromag ZM100A-33.
