What is the maximum hanger support spacing for horizontal 1" O.D. smooth wall tubing?

The maximum hanger support spacing for horizontal 1" O.D. smooth wall tubing is determined by industry standards to ensure the integrity and safety of the piping system. In this case, the correct answer indicates a spacing of 8 feet.

This spacing guideline is based on the physical properties of the tubing, including its weight and flexibility. Proper spacing is essential to prevent sagging or undue stress on the joints and connections, which can lead to potential leaks or failures in the system. The 8-foot spacing provides sufficient support while allowing for expansion and contraction due to temperature changes, thus maintaining the performance and reliability of the gas delivery system.

Understanding these parameters is crucial for technicians, as adhering to these standards not only ensures compliance with regulations but also promotes overall safety in gas piping installations.
