Pipefitting is the process of assembling, installing, and connecting pipes for various purposes such as plumbing, heating, cooling systems or industrial applications. It requires a combination of technical knowledge and physical skills to complete tasks safely and efficiently. Pipefitters must have an understanding of different types of piping materials and their properties in order to install them correctly. They must also be familiar with local building codes that dictate which type of pipe should be used in certain situations.

Since pipefitting involves working with many components including valves, fittings, flanges, elbows and couplings; it’s essential that pipefitters understand the principles behind each piece so they can properly join them together. This includes being able to measure accurately and cut pipes precisely according to plan specifications. In addition to these skills they must know how to use tools such as saws, wrenches and impact drivers appropriately when dealing with metal piping components like steel or copper tubes. To ensure quality control on all projects it’s important for pipefitters to test connections regularly using pressure testing equipment before sealing off joints permanently with solder or glue depending on material type.
