ABSTRACT:
An electrical charge dissipation device is interposed between two sections of a fluid flow line and is operative to dissipate electrical charges present therein in order to reduce corrosion. The charge dissipation device comprises an elongated tubular portion having a central longitudinal axis and including a surrounding sidewall forming an interior passage therefor. Opposite first and second ends are adapted to interconnect respectively with the two sections whereby the tubular portion is interposed therebetween such that fluid flows through the interior passageway. A charge collector is disposed in the interior passageway in electrical isolation from each of the two sections and includes a plurality of longitudinally spaced apart conductors organized in a selected array. These conductors operate to conduct electrical charges contained in the fluid exteriorly of the tubular portion whereby they may be dissipated to an electrical ground. Preferably, the charge collector is formed by a plurality of rigid conductors which are longitudinally and angularly spaced apart within the interior passageway.
