What is a Bellmouth?

Bellmouth is a term used in the context of pipes and tubing to describe a type of flared end that is commonly used on the outlet side of a pipe or tube. The flared end is formed into a bell-shaped shape, which provides a smooth transition from the pipe or tube to the next component in the system, such as a fitting or connection.

The purpose of a bellmouth is to provide a gradual increase in the diameter of the pipe or tube, which helps to reduce turbulence and pressure loss in the system. This is particularly important in applications where high flow rates are required, such as in water supply systems, chemical processing plants, and other industrial settings.

Bellmouths can be made from a variety of materials, including metals such as stainless steel and carbon steel, as well as plastic materials such as PVC and HDPE. They are typically installed using welding or mechanical connections, and can be custom-made to fit specific application requirements.
