For 1 1/2" NPS medical gas and vacuum system piping, what is the required hanger pipe support spacing?

The required hanger pipe support spacing for 1 1/2" NPS medical gas and vacuum system piping is 10 feet. This specification is in accordance with standards for ensuring the structural integrity and safety of the piping system. Proper spacing of hangers is critical to prevent sagging and potential failures, which could compromise the medical gas supply or vacuum system.

In the context of medical facilities, maintaining the integrity of gas and vacuum systems is essential for patient care, making adherence to these standards particularly important. The 10-foot spacing helps balance support and material use, contributing to a reliable and compliant installation.

This choice is rooted in the need for stability and safety in environments where medical gases are vital for life support and treatment. If the spacing were shorter or longer than specified, it could lead to issues with the performance and safety of the medical gas system, emphasizing the importance of strict adherence to the established guidelines.
