What is the maximum distance allowed between horizontal supports for 2-inch nominal size steel gas pipe?

For a 2-inch nominal size steel gas pipe, the maximum distance allowed between horizontal supports is 10 feet. This standard is guided by safety and structural integrity considerations outlined in relevant plumbing and gas codes.

The regulations ensure adequate support to prevent sagging or bending of the pipe over time, which could lead to leaks or failures in the gas delivery system. Supporting the pipe at this interval ensures that it is stable while also allowing for thermal expansion, which can occur due to changes in temperature as gases flow through the pipe.

By maintaining a support spacing of 10 feet, the system can function properly while minimizing risks associated with unsupported spans that could compromise the operation and safety of the gas piping. This adherence to code is essential for the prevention of hazards associated with natural gas systems.
