How should a gas line be routed when it passes through walls?

When routing a gas line through walls, it is essential to sleeve the line to protect it against potential damage. Sleeving provides a barrier that safeguards the gas line from friction, abrasion, and impact that could occur during construction activities or from other building elements. This protective measure is crucial for maintaining the integrity of the gas line, which, if compromised, could lead to leaks and pose safety hazards.

In many building codes and regulations, sleeving is a specified requirement for gas piping that passes through walls, as it helps ensure compliance with safety standards. The sleeve also allows for expansion and contraction of the pipe due to temperature fluctuations, reducing the risk of stress on the connection points.

Routing a gas line exposed, running it directly through a wall without support, or wrapping it in insulation does not provide the same level of protection as sleeving and can lead to increased wear and risk of damage to the gas line over time. Therefore, sleeving is the most appropriate method for routing a gas line through walls to ensure safety and reliability.
