Pipefitters are sometimes more specifically known as steamfitters or gasfitters. They fabricate, install, maintain, assemble, and repair piping systems. These systems include cooling, hydraulic, pneumatic, and high-pressure assemblies that transport water, steam, chemicals, or fuel for commercial, industrial, or marine use. In addition to welding, pipefitters often utilize a wide range of other processes throughout the course of their work, including cutting, threading, brazing, soldering, bending, and grooving.
