When calculating offsets for piping, which angle is primarily used for standard elbows?

In piping applications, standard elbows are primarily designed to change the direction of piping flow and are most commonly available in several angles, with the 90-degree elbow being the most frequently used.

When calculating offsets, which are necessary for routing pipes around obstacles or to adjust elevations, the 90-degree elbow is typically employed to create a sharp turn, allowing for a complete change in the direction of the piping. This is especially useful in environments where space is limited, or where a direct route may not be feasible due to structural components.

The use of a 90-degree elbow can simplify calculations, as it provides a straightforward angular change, allowing for easier determination of lengths and offsets needed in the installation. The ability to create sharp turns without excessive length makes the 90-degree elbow essential for efficient piping design and installation in various applications. Other angles like 30, 45, and 60 degrees are also used occasionally for specific situations, but the 90-degree elbow remains the standard for most offset calculations.
