Custom Pipe Fittings

Metal vs. Plastic Duct


Plastic pipe (or PVC pipe) is unsuitable for dust collection for three reasons:

First, plastic pipe fittings are not offered in the diversity required to meet design requirements.

Second, plastic pipe elbows have a short radius, which encourages clogs and compromises system efficiency.

Third, and most important, plastic pipe is non-conductive and builds up a static charge as charged particles pass through it.

This static charge can discharge at any time causing shock and surprise, which is dangerous around running machinery. More serious is the risk of explosion and fire. Fine dust particles suspended in air have significant explosion potential—all that is needed is a spark, which the static charge on plastic pipe conveniently supplies. Grounding plastic pipe requires wrapping it in wire both inside and out—an expensive (and never certain) proposition that negates the minimal price savings in going to plastic in the first place.

Spiral steel pipe has none of these disadvantages. An incredible variety of fittings are available and custom fittings can be easily fabricated. The fittings are designed with long radius to minimize clogging, and special fittings such as clean-outs and quick disconnects are available. Most important, Spiral metal pipe is conductive, and simple and easy to ground, even when flexible rubber hose is used to connect the duct to the machine.
