Quick Answer
Ground movement is unlikely to affect propane lines, as they are typically installed above ground or in a trench with a stable bottom. However, you should still consider factors like soil type, depth, and settlement when installing propane lines.
Understanding Propane Line Installation
Propane lines are generally not affected by ground movement due to their design and installation methods. Above-ground installations, which are common for propane tanks and lines, are less susceptible to ground movement. However, if you’re installing a propane line in a trench, ensure the bottom of the trench is stable and not prone to settling or erosion.
Installing Propane Lines Safely
When installing propane lines, follow the National Fuel Gas Code (NFPA 58) and local regulations. Dig trenches with a depth of at least 12 inches to allow for easy installation and maintenance. Use a trench box or shoring to prevent collapse, especially in unstable soil or high-traffic areas. Install the line with a minimum of 12 inches of cover to protect it from damage and reduce the risk of leaks.
Considering Soil and Terrain
When installing propane lines in areas with high ground movement potential, such as near slopes or in expansive soils, consider using flexible or corrugated lines. These lines can absorb minor movements without compromising the system. If you’re working in an area with unstable soil, consider consulting with a professional or using specialized equipment to minimize risks.
