ECN Forum Forums General Topics of the Trade General Discussion Area Fiberglass piping in chemical atmospheres

I seem to remember seeing something about a conductor installed inside piping to eliminate static buildup. I don't remember any thing more about it though.

Redsy,
You might be referring to the practice of putting a bare wire inside nonmetallic piping for dusts, grain, and the like. Most dust extractors for woodworking equipment have that setup. I have seen the fiberglass pipe with the conductive fibers in use, but not designed one. Usually, the system or mechanical engineer does the design. In all of these cases, proper bonding of the electrical installation is critical so that the static wire doesn't inadvertently become a lit fuse in case of a fault.
