Pipeline static grounding
Thread Content
Who can help solve the problem of static grounding for pipes?
The specific question you asked isn’t quite clear; it would be better if you could be more specific.
Which medium pipelines must be electrically grounded? What are the requirements for the grounding connection points and grounding resistance values of pipe networks? Answer: Pipelines for combustible gases, liquefied hydrocarbons, combustible liquids, and combustible solids shall be equipped with static grounding facilities at the following locations: (1) For pipelines within each relatively independent building or structure in the plant area, static grounding can be achieved by connecting them to the metal casing of the process equipment (via flange connections) ； (2) Grounding connection points should be provided at pumps, filters, buffers, etc., within the pipeline network ； (3) The pipelines in the pipeline network at the entrances and exits to the plant area, at the boundaries between different explosion-hazardous areas, and at pipeline branch points should be grounded; for long-distance pipelines without branches, they should be reliably connected to grounding electrodes every 80–100 meters ； (4) For the non-conductive sections in the middle of metal pipes (such as PVC pipes), in addition to shielding protection, the metal pipes at both ends should be connected to the grounding main line respectively, or bridged with 6mm² multi-core insulated copper wires and then grounded ； (5) Metal components on non-conductive pipe sections shall be grounded. The grounding resistance value of the dedicated static grounding electrode in each group should be less than 100Ω ； In areas with high soil resistivity in mountainous regions, the ground resistance value should be less than 1000Ω.
SH 3097-2000 – This standard, the \"Code for Design of Static Grounding in Petrochemical Industries\", should be available on the forum; find it and read it at your own pace. . Hope to see your own thoughts in a reply; P
The integral is too low; normalization isn’t possible. I’ve learned from all of you.
Pipeline grounding? But all I know is that the flanges between the pipes are definitely copper sheets used for bridging.
