What is the correct diameter of a drip leg serving a 14" steam main?

The correct diameter of a drip leg serving a 14" steam main is based on industry standards that dictate the size of drip legs in relation to the size of the steam main they service. Drip legs are essential in the steam system as they collect condensate that forms during the steam process, preventing potential operational issues.

For a 14" steam main, a drip leg with an 8" diameter is appropriate because it effectively accommodates the expected volume of condensate and steam venting while ensuring that the system can manage condensation without risking blockages or inefficiencies. The sizing is typically determined by factors such as the steam main diameter, operating pressure, and the nature of the steam system.

Choosing an 8" diameter allows the drip leg to efficiently handle the water flow and ensure proper drainage, minimizing maintenance needs and maximizing system performance.
