Installs or repairs water, steam, gas or other types of pipe and
pipefittings. Work involves most of the following: Laying out work and
measuring to locate position of pipe from drawings or other written
specifications; cutting various sizes of pipe to correct lengths with
chisel and hammer, oxyacetylene torch or pipe-cutting machines; threading
pipe with stocks and dies, bending pipe by hand-driven or power-driven
machines; assembling pipe with couplings and fastening pipe to hangers;
making standard shop computations relating to pressures, flow and size of
pipe required; and making standard tests to determine whether finished
pipes meet specifications. In general, the work of the maintenance
pipefitter requires rounded training and experience usually acquired through a formal apprenticeship or equivalent
training and experience.
Workers primarily engaged in installing and repairing building sanitation or heating systems are excluded.
