Pipe fitting is the occupation of installing or repairing piping or
tubing systems that convey liquid, gas, and occasionally solid
materials. This work involves selecting and preparing pipe or
tubing, joining it together by various means, and the location and
repair of leaks.
Pipe fitting work is done in many different settings: HVAC,
manufacturing, hydraulics, refineries, nuclear-powered
Supercarriersand Fast Attack Submarines computer chip fab plants,
power plant construction and other steam systems. Pipe fitters
(sometimes called simply "fitters") are represented in the USA and
Canada by the United Association of Journeymen and Apprentices of
the Plumbing and Pipe Fitting Industry of the United States and
Fitters work with a variety of pipe and tubing materials including
several types of steel, copper, iron, aluminium, and plastic. Pipe
fitting is not plumbing; the two are related but separate trades.
Pipe fitters who specialize in fire prevention are called
Sprinklerfitters, another related, but separate trade.
Materials, techniques, and usages vary from country to country as
different nations have different standards to install pipe.
