Short answer: oil and gas electrical grounding should be selected by corrosion class, hazardous area rules, bonding continuity, conductor material, connection reliability and inspection requirements.
| Corrosion control | Use tinned copper, stainless steel, copper bonded steel or specified materials according to site chemicals and salt exposure. |
|---|---|
| Bonding conductors | Confirm cable, strip, braid or jumper size for tanks, skids, pipelines and panels. |
| Connections | Use exothermic welding or approved mechanical clamps according to inspection and maintenance rules. |
| Lightning and surge | Coordinate ground rods, air terminals, down conductors, SPDs and earth bars. |
Oil and gas grounding cannot be selected only by conductor size. Corrosion, inspection rules and hazardous area requirements must be checked.
