What is the maximum vertical distance between hangers on a 2" steel gas pipe?

The maximum vertical distance between hangers on a 2" steel gas pipe is determined by the need to support the pipe effectively, taking into account the pipe's weight and ensuring proper alignment. Proper support is crucial to prevent sagging, bending, or other structural issues that can compromise the integrity of the gas line.

When installing hangers for steel gas piping, the best practice is to install them at every floor level. This approach provides a consistent and secure point of support, allowing the weight of the pipe to be adequately distributed. By minimizing the distance between hangers, you reduce the risk of mechanical stress and potential failure of the piping system.

The other options suggest varying distances that do not align with the best practices for supporting gas piping. For instance, spacing hangers no more than 10 feet or a maximum of 8 feet allows for more significant gaps, which could lead to inadequate support. Similarly, hanging pipes every second floor does not provide the necessary support required for maintaining the integrity and safety of the gas line. Therefore, supporting the pipe at every floor leverages structural stability and adheres to industry standards.
