What is the minimum burial depth for underground gas piping?

The minimum burial depth for underground gas piping is 12 inches. This requirement is set to ensure that the piping is adequately protected from physical damage and adverse environmental conditions. Adequate burial depth helps to prevent accidental contact with the piping, such as during digging or landscaping activities, and provides a buffer against freezing temperatures and soil movement that could affect the integrity of the pipeline.

Additionally, this depth is consistent with industry standards and safety regulations designed to minimize risks associated with gas leaks and ensure long-term reliability. Adhering to these guidelines is critical for the safe installation and maintenance of gas systems.
