Ensuring reliable electrical bonding in hazardous areas is critical for safety in oil and gas operations. This article presents a proven method for bridging insulated stainless-steel flanges using 35 mm² insulated copper bonding jumpers. Field applications confirmed continuity resistance below 0.05 Ω in alignment with IEC 60079-14, IEC 60364-5-54, IEEE Std 142, and NFPA 77.
The solution addresses real-world constraints, including mechanical congestion and compatibility with electric heat-tracing systems. It offers a structured framework for electrical engineers and safety specialists seeking to enhance grounding integrity, eliminate ignition hazards, and prevent electric shock due to stray or induced voltages on isolated pipe sections.
