What is the maximum suggested pipe support spacing for 6 inch steam gas or air service?

• A. 15'
• B. 21'
• C. 30'
• D. 12'

Answer: (B)

For a 6 inch steam, gas, or air service, the maximum suggested pipe support spacing is 21 feet. This recommendation is based on industry standards that ensure the pipe is adequately supported to prevent sagging and to maintain proper alignment. Proper spacing of supports is critical because it helps distribute the weight of the pipe and its contents evenly, reducing stress on both the pipe and the connected fittings and joints. When supports are too far apart, pipes may experience excessive bending moments, which can lead to premature failure, leaks, or damage over time. This spacing specifically takes into account the unique characteristics of the materials and conditions involved in handling steam, gas, or air. A spacing of 21 feet is typically accepted for 6 inch pipes under these conditions, balancing sufficient support with practical installation concerns. The other options represent either too little or too much spacing, which could compromise the integrity and safety of the piping system.
