Pipe fitting is the process of connecting various sections of pipes to create a complete system for transporting fluids or gases. This involves using different types of fittings, such as elbows, tees, and couplings, to change the direction or size of the piping. Proper pipe fitting ensures that the system operates efficiently and safely. In addition to connecting pipes, pipe fitting also includes tasks like cutting, threading, and welding. Skilled pipe fitters must understand the properties of different materials, such as PVC, copper, or steel, to select the right components for each project. This expertise is essential in industries like construction and manufacturing.
