<p>In some embodiments, an apparatus comprises a gasket (500, 620) configured for positioning between an end of a first drill pipe and an end of a second drill pipe, wherein the end of the first drill pipe (602) includes an inductive coil ring (610) and the end of the second drill pipe (604) includes an inductive coil ring (616). The gasket includes an outer ring (506, 624) that is comprised of an elastic magnetic material that is essentially nonconductive. The outer ring has a diameter that is greater than the diameters of the inductive coil rings. The gasket includes an inner ring (502, 622) 6 that is comprised of an elastic magnetic material that is essentially nonconductive. The inner ring has a diameter that is smaller than the diameters of the inductive coil rings, wherein the gasket is to be positioned such that the outer ring and the inner ring are outside and inside, respectively, the diameters of the inductive coil rings.</p> |
