What is the purpose of burying or covering piping?

To improve aesthetic appearance
To protect against excavation and damage
To prevent gas leaks into the atmosphere
To comply with local building codes

The correct answer is: To protect against excavation and damage

Burying or covering gas piping serves multiple important purposes, with the primary goal of protecting the piping from excavation and damage. Gas pipes, especially those carrying natural gas or propane, are vulnerable to physical harm from construction activities, heavy machinery, and natural elements. When buried or covered, these pipes are less exposed to potential impact, which significantly reduces the risk of a rupture or leak that could lead to dangerous situations. In addition to physical protection, covering the piping can also help mitigate risks related to environmental factors, such as frost heave or soil erosion. This gives added durability to the installation and ensures that the integrity of the gas delivery system remains intact over time. While aesthetics, prevention of gas leaks, and compliance with building codes are associated with piping installation, the primary reason for burial or covering stems from the need to safeguard the integrity of the piping system from external forces and potential damage.
