What is the minimum support spacing for 1-1/4" or larger gas pipe when positioned horizontally?

The minimum support spacing for 1-1/4" or larger gas pipe when positioned horizontally is indeed 10 feet. This standard is established to ensure the structural integrity and safety of the gas piping system. Proper support helps to prevent sagging and reduces the risk of stresses that could lead to joint failure or pipe damage over time.

The spacing requirements take into account the weight of the pipe and the materials that may flow through it, as well as environmental factors that could affect its stability. By adhering to a 10-foot spacing, installers maintain compliance with regulations and best practices that promote safety in gas installations. Proper support is critical in maintaining a secure system, which is especially important for flammable gas lines.
