What is the minimum angle for rising run-outs in gas piping systems?

The minimum angle for rising run-outs in gas piping systems is 45 degrees. This angle is important as it allows for proper drainage of condensate that may accumulate in the gas line. When a gas pipeline is installed with a rise, having at least a 45-degree angle ensures that any liquid that may condense within the gas line can efficiently flow back towards the source or designated drainage point.

In systems where the angle is less than 45 degrees, there can be a tendency for liquids to pool within the line, which can lead to issues such as pressure drops, corrosion, or even blockages over time. A 45-degree angle strikes a balance between efficient drainage and the installation constraints commonly faced in medical gas systems, making it the minimum recommended angle. This consideration is crucial for maintaining the integrity and safety of gas piping systems in medical settings, where reliability and compliance with regulations are paramount.
