When installing gas pipes near structures, they should be kept at least how far above grade or the structure?

Keeping gas pipes at least 6 inches above grade or any structure is a safety standard designed to prevent potential hazards associated with gas leaks and to ensure proper drainage away from the pipe. This distance helps to minimize the risk of accidental damage, water accumulation, and potential corrosion of the pipes, which can all compromise the integrity of the gas system.

By maintaining this height, any water or debris is less likely to collect around the gas pipes, reducing the chance of a leak or incident. Additionally, having the gas pipes elevated at this height aids in visibility and accessibility for maintenance and inspection, allowing for quick identification of any issues that might arise. This height requirement is a crucial part of codes and regulations focused on ensuring the safe installation and operation of gas piping systems.
