Recently, an operator saw an arch jump between a top bolt and the filter housing, a distance of about 2 inches. The filter is of spirally-wound cotton; it does not contact the wall of the filter housing. A long bolt runs axially through the middle of the filter housing holding the top head and bottom head together. Viton gaskets are used. The hoses connecting to the filter have conductive strips and the couplings are bonded to the grounding network. The filter housing is bonded to a coupling.
There are a lot of new people in this facility who maybe didn't learn all the tricks they should have. They say that they've never seen this before.
One of the old timers says they bonded the top bolt to the filter housing using a wire and two washers. This seems like a good way to avoid an arch. Also, perhaps a 30 second pause after flowing from storage to operations use would be a good idea.
What do you think?
