Abstract:
A method to prevent the accumulation of static electricity in a pipe system for containing corrosive petroleum products is provided, for a total resistance of less than 1 MEG ohms to ground from all points. The pipe system has at least two pipe sections, each comprising a structural layer and a corrosion resistant layer. The corrosion resistant layer has at least a conductive surface area in contact with the fluid, with the conductive surface area defining an electrical pathway extending a length of the pipe section. Each pipe section has a tapered end exposing a portion of the corrosion resistant layer. The method comprises joining the two pipe sections at the tapered ends by a conductive adhesive overlay, and electrically connecting the conductive adhesive overlay to a grounding device, wherein the grounding device helps dissipate build-up of electrostatic charge in the pipe system carrying the fluid.
