How often should a 1/2-inch steel gas pipe be supported according to general plumbing standards?

Every 3 feet
Every 6 feet
Every 8 feet
Every 10 feet

The correct answer is: Every 6 feet

The correct support spacing for a 1/2-inch steel gas pipe according to general plumbing standards is every 6 feet. This guideline ensures that the pipe remains stable and secure throughout its installation, preventing sagging or excessive movement that could lead to potential leaks or failures. Supporting the pipe at this interval is crucial for maintaining the integrity of the gas system, as it can be subjected to various stresses and environmental factors over time. Proper support helps to distribute weight and force along the length of the pipe, mitigating the risk of damage and ensuring safe operation. While other support intervals exist for different sizes or types of piping, the 6-foot standard for a 1/2-inch steel gas pipe is specifically defined in plumbing codes to promote safety and reliability in gas transport systems.
