I would like to know what the principle behind pipeline static electricity bonding wires is If it is the drainage of the acetylene main pipe and no jumper wire is connected, will static electricity then react with acetylene?

Static bypass wire? Was static electricity finally introduced to the grounded terminal?
The function of an electrostatic jumper is to bring the connected workpieces to an equipotential state with respect to ground. Since they are at the same potential, there is no voltage difference, and therefore no electric sparks will be generated between these workpieces due to static electricity accumulation (equipotential states do not allow discharge). Since static discharge wires generally also have a grounded terminal, this static electricity can be directed into the ground. The ground being yin in nature, it absorbs the energy of the static electricity, bringing it to a state of calmness and stability.
Electrostatic accumulation acts as a ignition source, leading to an explosion
During transportation, friction between the medium and the pipe walls, or collisions between particles of the same medium, generate static electricity, and the amount of such charge is very large. It must be conducted to the ground through continuously connected metal pipes or metal grounding circuits; otherwise, risks will arise. This is similar to the dragging contact at the rear of a tanker truck. A jumper wire serves the function of a continuous metal conductor.
Thank you very much for answering my questions. I would like to ask further: in a long-distance pipeline with many water seal tanks, and since these tanks need to have their waste discharged regularly, does the jumper wire for the discharge valve only need to pass through the flange, without the need for grounding? And it’s sufficient as long as there is one grounding point for this long-distance pipeline, right?

I would like to ask further: in a long-distance pipeline with many water seal tanks, and since these tanks need to have their waste discharged regularly, does the jumper wire for the discharge valve simply need to be connected across the flange, without any need for grounding? And it’s okay as long as there is one grounding point (at the end) on this long-distance pipeline, right?
【Reply to Floor 4】 Thank you very much for your answers.
