What is the primary purpose of a steam trap?

The primary purpose of a steam trap is to remove condensate and non-condensable gases from steam systems while preventing the escape of live steam. In steam heating systems, steam condenses into water (condensate) as it releases heat. This condensate must be efficiently removed to maintain system efficiency and prevent waterlogging, which can lead to various operational issues, including reduced heat transfer and potential equipment damage.

Additionally, steam traps help eliminate non-condensable gases, such as air, which can undermine the thermal performance of the system and lead to corrosion. By effectively managing these two elements, steam traps contribute to the overall efficiency, safety, and reliability of steam systems. This function distinguishes steam traps as essential components in ensuring effective steam utilization and system integrity.
