What is the take-off of 16" in 45° butt weld ells?

In the context of pipefitting, the term "take-off" refers to the length from the centerline of the pipe to the end of the fitting. For a 45° butt weld elbow, the take-off is calculated based on the diameter of the pipe and the angle of the fitting.

For a 16-inch diameter pipe, the take-off length for a 45° elbow is generally determined using a standardized formula that considers both the diameter of the pipe and the angle of the elbow. The common take-off for a 45° elbow is approximately 10 inches. This value can vary slightly based on specific design and manufacturing tolerances, but in practice, 10 inches is widely accepted as the take-off length for a 16-inch pipe with a 45° fitting.

This calculation helps pipefitters and other professionals in the industry to accurately measure and cut pipe lengths needed for installation, ensuring that the fittings can be installed correctly and efficiently. Thus, when considering the take-off for a 16" in 45° butt weld ell, 10 inches is the appropriate and widely recognized value.
