Which of the following statements is correct regarding support spacing for gas pipes?

The correct statement regarding support spacing for gas pipes is that support spacing increases with the diameter of the gas pipe. This means that larger diameter gas pipes require greater support spacing to ensure proper stability and to accommodate the increased weight and potential differences in thermal expansion.

Larger pipes are typically heavier and may experience more strain due to pressure and temperature changes. Consequently, adequate support not only prevents sagging but also helps maintain the integrity of the piping system. As the diameter of the pipes increases, the structural requirements change, necessitating adjustments in the spacing of supports to ensure safety and compliance with plumbing codes.

Support spacings for gas pipes are defined in standards and building codes to promote safe installation and operation. Therefore, understanding the relationship between pipe diameter and required support spacing is crucial for ensuring the efficient functioning of a gas piping system.
