Pipe Threading
Pipe Threading is a fundamental skill in plumbing where workers create spiral grooves (called threads) on the ends of pipes so they can be securely connected together. Think of it like creating the spiral pattern on a screw, but for pipes. This process allows pipes to be joined without welding, making it easier to both assemble and take apart plumbing systems when needed. Plumbers use special tools called pipe threaders to do this work, which can be either manual or powered by electricity. This is one of the basic but essential skills that plumbers need to know for installing and maintaining pipe systems in homes, buildings, and industrial settings.
