What does the term "bull headed tee" describe?

The term "bull headed tee" refers to a specific type of fitting where all flow enters or exits through the branch opening. This design allows for a larger mainline pipe to connect directly to a smaller branch line at a right angle. The unique construction facilitates increased flow capabilities through the branch, as it directs the fluid through a single point rather than splitting it between multiple outlets.

In the context of plumbing or piping systems, understanding the function of a bull headed tee is crucial for tasks that require efficient fluid dynamics. It is particularly beneficial in scenarios where maintaining a singular flow path is necessary, such as in drainage systems where a concentrated outlet is required for effective disposal.

Other options describe different types of fittings or flow characteristics that do not apply to the bull headed tee. For example, the notion of splitting flow equally aligns with a different fitting type, while a reduction in pipe size indicates a different purpose altogether. Thus, recognizing the accurate term and its function is vital for appropriate application in steamfitting and piping systems.
