Pipe fitting work is done in many different trades: Plumbing, HVAC, manufacturing, fire prevention, and many others. Pipe fitters(sometimes called simply "fitters") are represented in the USA by the United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry of the United States and Canada.Fitters work with a variety of pipe and tubing materials including several types of plastic, copper, steel, iron, aluminium, clay, and lead.
Steel pipe (or black iron pipe) was once the most popular choice for supply of water and flammable gases, but fell from favor as water pipe in the mid 20th century due to its tendency to rust. Steel pipe is still used in many homes and businesses to convey natural gas or propane, and is a popular choice in fire sprinkler systems due to its high heat resistance.
