Steamfitter's / PipeFitters
Job Description: 
Installss and maintains pipes to carry water, steam, compressed air, gas, and fluids needed for processing, manufacturing, heating and cooling.  They work on high and low pressure pipes, power stations, refrigeration or air-conditioning units, heating systems and services steam and hot water heating systems; air-conditioning and refrigeration systems; nuclear and fossil fuel power plants; industrial and commercial instrument systems; cross country pipe lines; chemical and petro-chemical plants; complete environmental systems in hospitals, schools, churches, high-rise office and apartment buildings; water and sewage treatment plants, food processing plants; pharmaceutical manufacturing plants; and most other installations requiring piping.

The pipe or tubing may be copper, steel, cast or wrought iron, brass, bronze, glass, plastic, concrete or any material from which pipe can be made. The size ranges from 1/16" up to 10 feet and larger in diameter.
