Where should steam traps be installed within a system?

Steam traps are designed to remove condensate, air, and other non-condensable gases from steam systems to ensure efficient performance. Installing steam traps below the lowest point in a system is effective because condensate naturally drains downhill due to gravity. This placement allows the trap to effectively collect and remove condensate as it forms, preventing water accumulation that can lead to inefficiencies and damage within the system.

When traps are at the highest point, they may not effectively collect the condensate, as the water would not flow upward. If installed at the midpoint, there could also be challenges in ensuring proper drainage, as it may not be the optimal location for condensate removal. Similarly, placing traps at a pressure relief point doesn't facilitate efficient condensate drainage and doesn't leverage gravity effectively.

Thus, the correct installation of steam traps below the lowest point is crucial for maintaining an efficient and properly functioning steam system.
