What is the maximum spacing allowed between hangers supporting 3/4-inch steel gas piping?

The maximum spacing allowed between hangers supporting 3/4-inch steel gas piping is 8 feet. This requirement is based on industry standards that specify spacing to ensure adequate support and prevent sagging or thermal expansion issues in the piping system.

When piping is not properly supported, it can lead to stress on joints and connections, which may result in leaks or failures. Spacing hangers at 8 feet for 3/4-inch steel gas piping provides sufficient support while allowing for some movement due to temperature changes.

Proper support is critical in maintaining the integrity of piping systems, ensuring safety and functionality, especially in applications involving gases. The other options represent distances that exceed the recommended maximum, which could compromise the structural integrity of the piping system.
