What is the minimum spacing for support of gas pipe that is 1-1/4" or larger, when placed vertically?

The minimum spacing for support of gas pipe that is 1-1/4" or larger, when placed vertically, is specified to be every floor level. This requirement is in place for several important reasons.

First, vertical support at every floor level helps to ensure that the gas piping is adequately secured against movement and stress caused by temperature fluctuations, structural shifts, and external forces. This stability is particularly critical for gas lines as any movement can lead to damage or, worse, gas leaks which pose significant safety hazards.

Additionally, securing the gas pipe at every floor level helps in maintaining proper alignment and prevents sagging, which could affect the integrity of the system. It also makes inspections easier, allowing for better effectiveness in monitoring the system for wear and potential leaks.

The rationale behind this regulation is rooted in safety considerations and the need to maintain the structural integrity of the piping system throughout its length, ensuring the safe delivery of gas in residential or commercial settings.
