The correct response to the statement regarding the installation of drip legs is true. Drip legs are essential components installed within piping systems, particularly in the context of gas and steam lines. Their primary purpose is to collect any condensate, moisture, or solid particles that might accumulate in the system, preventing these substances from causing damage to equipment or affecting the efficiency of the operation. Installing drip legs at low points is crucial because this is where liquids tend to settle due to gravity. By placing drip legs at the end of mains and prior to any risers, it ensures that any potential buildup is effectively captured before the flow encounters vertical changes that could lead to operational issues, such as water hammer, corrosion, or blockages. Additionally, strategically positioning drip legs in these locations helps in routine maintenance and facilitates the safe and effective operation of the piping system, allowing for easy drainage of collected condensate without needing extensive system downtime or disassembly. This practice ultimately promotes a more reliable and efficient piping system.
