In gas installations, what is the acceptable method for supporting and securing gas piping?

The acceptable method for supporting and securing gas piping involves spacing supports according to the weight and type of the pipe. This is crucial because proper support prevents sagging, bending, or movement that can lead to stress on the joints and connections. Different types of piping materials (such as steel, PVC, or copper) have different weights and characteristics, which dictates how far apart supports should be placed to ensure stability and safety.

Support spacing standards are provided in the National Fuel Gas Code, which helps ensure that installations can withstand everyday stresses, environmental factors, and potential impacts. Adequate support is vital for maintaining the integrity of the gas piping system and preventing leaks, which can pose serious safety hazards.

Other options present approaches that do not meet safety and code requirements. For example, spacing supports at random intervals could lead to improper support and potential failure of the piping system. The idea that supports must be made from wood overlooks the need for materials that are appropriate to the specific installation environment and the pipe material. Lastly, the notion that support is unnecessary for lightweight pipes does not take into account the requirement for all piping to be adequately supported to prevent movement, regardless of weight. Installing gas piping without sufficient support can create hazards and is not compliant with code regulations.
