What is the non-standard term used for a pipe fitting that connects at a right angle?

The term "elbows" is commonly used in plumbing and piping to refer to a fitting that connects two pipes at a right angle, typically at 90 degrees. This type of fitting allows for the change of direction within a piping system, which is essential for navigating around obstacles and directing the flow of fluids. Elbows are a fundamental component of piping systems due to their versatility and functionality, as they can accommodate various pipe diameters and materials, and can be produced in different radius lengths to suit specific installation requirements.

In the context of piping terminology, "angle fittings" and "right connections" are not standard industry terms, making them less recognizable to professionals in the field. Meanwhile, "orthogonal fittings" may describe a similar concept but is not widely used in practice. Therefore, "elbows" stands out as the correct and standard term for this specific type of pipe fitting.
