What is the name of the highest point of a pipe?

The highest point of a pipe is referred to as the crown. This terminology is commonly used in the context of drainage and sewer systems to describe the uppermost part of a pipe, where the pipe's curvature is at its peak. Understanding the concept of the crown is important for various aspects of pipeline design, such as ensuring proper flow and drainage. When considering fluid dynamics within pipes, the crown also plays a crucial role because it helps to minimize the possibility of standing water, which could lead to blockages or other issues in the system.

The other terms have specific meanings in the context of pipes. The springline is the horizontal centerline of the pipe, the invert refers to the lowest point inside the pipe, and a valve is a component used to control flow within a piping system. Each serves an important function, but none accurately describe the highest point of a pipe, confirming the crown as the correct answer.
