Describe what 'bending' entails in pipefitting.

Bending in pipefitting refers specifically to the technique of altering the direction of a pipe while maintaining its integrity and without the need for cutting it. This is crucial in piping systems, where space constraints and configurational requirements often necessitate changes in direction. Instead of using multiple fittings and joints, which could introduce more complexity, potential leak points, and increased labor, bending allows for a smooth transition in the flow of materials through the pipe.

This process can involve specialized equipment that applies heat and pressure to achieve the desired curvature. Bending helps to ensure that the flow characteristics are maintained, and it can also enhance the overall aesthetic and structural stability of the installation. This makes it a highly efficient and effective method for managing pipe routes in various applications.
