Plumbers/Pipefitters design and install various types of piping systems – hot water, sprinkling, lubricating, and heating or cooling systems, as well as systems that distribute water and remove waste, to name a few.
They may install new systems or modify older ones. In the past, plumbers installed the piping systems for most residential and commercial establishments. But today, the systems installed in most industrial and commercial complexes require the skills of professionally trained pipefitters. Pipefitters work with various piping materials and tools and must know the specific use of each. For example, oil, gas, and other chemicals require certain types of pipes and different types of seals and gaskets. Different pipes require different tools for assembly. Pipefitters also need to know local ordinances, state codes, and regulations regarding their work.
