What is haunching in the context of piping?

Haunching in the context of piping refers to the method of creating a springlike or horizontal centerline of the pipe, which is crucial for proper drainage and flow. This technique involves shaping the ground or bedding material beneath pipes to provide optimal support and alignment, ensuring that they remain securely in place and facilitate the correct flow of fluids. By maintaining this horizontal alignment, the risk of pipe damage due to misalignment or settling is minimized, which is essential for the longevity and efficacy of the piping system.

Understanding haunching is important for workers in utilities maintenance, as it directly impacts the performance and safety of pipelines. Inadequate support or improper alignment can lead to issues such as blockages or leaks, which can be costly and hazardous.
