Ducting, commonly known as conduit, refers to an enclosed passage or channel used for conveying air, gas, or liquid. It is an essential part of HVAC systems, electrical wiring, and plumbing. There are several synonyms for ducting, including tubing, pipe, hose, channel, conduit, and trough. Tubing is used to convey fluids and gases, while a pipe is a more significant conduit for large volumes of water, oil, or chemicals. Hoses are generally more flexible and used for the transportation of liquids. Channels, conduits, and troughs are used in engineering structures, and they help direct or contain the movement of fluids or materials.
