What is the bolt angle for a flange that has 16 bolt holes?

15 degrees
22.5 degrees
30 degrees
45 degrees

The correct answer is: 22.5 degrees

For a flange that has 16 bolt holes, the bolt angle can be calculated by taking the full circle of 360 degrees and dividing it by the number of bolt holes. In this case, you would divide 360 degrees by 16. This calculation yields 22.5 degrees for each bolt hole's center angle. This means that for each bolt, the angle between two adjacent bolts is 22.5 degrees, which allows for proper alignment and distribution of load when the flange is assembled. This precise angle is critical in ensuring even spacing for bolting, which contributes to the integrity and stability of the connection between flanges in piping systems.
