Steamfitters lay out, assemble, fabricate, install, troubleshoot, maintain and repair mechanical piping systems. These piping systems carry water, steam, chemicals, compressed air, liquids, gases or fuel. The systems are under extreme pressure, which requires precise cutting threading, grooving, bending, and welding. Fitters install high purity process piping for semiconductor, biotechnology and pharmaceutical manufacturing. This is the only trade to specialize in planning, design, and installation of low and high pressure steam systems.
The work is performed at various jobsites, including new construction, industrial, chemical, power and waste water treatment plants, and most other commercial or institutional buildings, as well as residential sites. Work is accomplished in buildings, trenches, on roofs or inside tunnels or confined spaces. Steamfitters operate various hand and power tools, heavy equipment, welding machines, cutting torches and other industry related equipment.
Work done on the job:
- Blueprint reading, drawings, specifications, detailed isometric sketches and layout of pipe and equipment fabrication and installation.
- Rigging, setting, supporting and piping of related equipment, valves, fittings, etc.
- Measure, cut, bend, prepare and join all types of pipe, including threading, welding, brazing, soldering, cementing, fusion and mechanical joining.
- Preparation of construction site for installation of equipment and piping, including walls, floors, ceilings, rooftops, shafts, etc.
- Pressure test systems to detect leaks prior to setup.
- Test systems to detect problems in electronic, pneumatic, digital, electrical, software or programmable logic controls.
- Works independently on proper piping practices in the industry and confirms proper function of installed/repaired piping systems and related equipment.
