Process piping transports large volumes of hot, dusty air from processing equipment to mills, baghouses and other process equipment. Process piping can be round or rectangular. Although circular ductwork is more expensive to manufacture than rectangular ductwork, it requires fewer stiffeners and is

When experimenting in the laboratory, there may be a lot of easily volatile harmful objects. If the minimum threshold of these easily volatile harmful objects reaches 50 parts per million, the laboratory must be opened quickly. Fume hood or some other equipment capable of exhausting air.
