What is the horizontal hanger spacing for 3/4" nominal steel gas piping?

Explanation:
Gas piping needs to be supported so it doesn’t sag, move, or put stress on joints. The distance between supports is set by the pipe size and the material, because heavier or larger pipes need closer supports to keep deflection under control. For a 3/4" nominal steel gas pipe running horizontally, the standard maximum spacing between hangers is eight feet. This span provides enough stiffness to prevent noticeable sag and reduces stress at connections, while still being practical to install. Additionally, a hanger is normally required within a short distance (about three feet) of any inlet or appliance to keep the connection from shifting. Larger diameter pipes use shorter spans, which is why eight feet is appropriate for this size.
