Abstract
According to some embodiments, a device for reducing magnetic force along a section of piping comprises a first end member comprising an opening, a second end member comprising an opening, at least one connecting member extending between the first end member and the second end member, the at least one connecting member secured to both the first and second end members, wherein the at least one connecting member defines a passageway that generally aligns with the openings of the first and second end members, and wherein the passageway and the central openings of the first and second members are sized and otherwise configured to accommodate a pipe section. The device further includes a coil configured to conduct electrical current.
Claims18
A device for reducing magnetic force along a section of piping, the device comprising:
- a first end member comprising a central opening;
- a second end member comprising a central opening;
- at least one connecting member extending between the first end member and the second end member, the at least one connecting member secured to both the first and second end members;
- wherein the at least one connecting member defines a passageway that generally aligns with the central openings of the first and second end members;
- and
- wherein the passageway and the central openings of the first and second members are sized and otherwise configured to accommodate a pipe section;
- and
- a coil configured to conduct electrical current;
- wherein the coil is positioned in a helical arrangement around the passageway along the at least connecting member;
- wherein the device is configured to be moved between a closed configuration and an open configuration, wherein in the closed configuration the coil is configured to surround piping, and wherein the device can be positioned over and removed from piping in the open configuration;
- wherein the coil is configured to couple to an electrical energy source for selectively delivering electrical current to the coil;
- and
- wherein the coil comprises at least one coil coupling, the at least one coil coupling being configured to removably couple adjacent portions of the coil, wherein the at least one coil coupling permits the coil to remain secured to the at least one connecting member when the device is in the closed and open orientations.
