Release of static electricity from hydrochloric acid exhaust pipes

When the gas concentration reaches the explosive limit, an explosion can occur due to static electricity. If the material remains unchanged. Add two flanges to the exhaust pipe, using graphite gaskets. Connect the graphite to the ground with a wire. Let the static electricity discharge. Can everyone take a look? Are there any other ways? # hcbbs
Hehe, we have considered this issue as well; at that time we thought about adding a metal wire inside the pipeline to discharge static electricity. However, from the perspective of system reliability, it is best to maintain a certain range of hydrogen chloride purity and to conduct regular inspections of the device.
The pipeline inside is emptied with hydrochloric acid – is it moist? If it is moist, then what you did makes sense, as the electrolytes will conduct electricity.
The inside of the hydrochloric acid vent pipeline is humid； Acidic gases will corrode metals, right?
