Water and Fuel Systems Maintenance (WFSM) Set A Volume 3 Practice Test

The maximum distance that hangers should be placed apart when hanging a steel pipe is 12 feet. This standard is designed to ensure adequate support for the weight of the pipe and the fluid it carries, as well as to accommodate thermal expansion and contraction.

When hangers are spaced too far apart, there is a risk of sagging or bending due to the weight of the pipe, which can lead to misalignment, stress on the joints, or even failure of the pipeline system. By maintaining a maximum spacing of 12 feet, the integrity of the pipe is preserved, ensuring that it functions reliably over time.

This distance is established based on various factors, such as the diameter and the weight of the pipe; larger pipes may require more support, but the 12-foot figure serves as a general guideline. It’s important to follow these standards to maintain safety and efficiency in water and fuel systems.
