What is the required diameter of a drip or dirt pocket in relation to the piping it serves?

The required diameter of a drip or dirt pocket must be at least 2 inches (50 mm) in relation to the piping it serves to effectively collect moisture and debris from the gas line. This size is important because it ensures that there is sufficient volume to trap contaminants without causing blockages in the piping system, which could lead to operational issues or hazards.

Designing drip pockets with this minimum diameter allows for better maintenance and management of the gas piping system, as it facilitates the removal of accumulated liquids and sediments. A diameter smaller than 2 inches may not provide the necessary capacity or efficiency to handle the expected conditions, while larger diameters might be unnecessarily cumbersome or complicate installation. Therefore, adhering to the 2-inch standard supports both safety and operational reliability in gas systems.
