Propane Gas Safety and Installation Certification Practice Test

For 3/4" or 1" steel pipe, the recommended spacing for supports is every 8 feet. This guideline is crucial for ensuring the structural integrity and safety of the piping system. Proper support helps to prevent excessive sagging or bending, which can lead to stress on the joints and potential leaks or failures in the system.

The 8-foot spacing recommendation balances the need to provide adequate support without over-bracing the system, allowing for thermal expansion and contraction, which can occur with changes in temperature. This consideration is vital for maintaining the longevity and reliability of the piping, particularly in applications involving propane gas, where safety is paramount.

Other spacing options, while potentially effective in other contexts, do not align with the standard practices recommended for 3/4" or 1" steel pipe installation, making the 8-foot distance the most appropriate choice for effective support and safety.
