FCI 18-2-2020的目的是帮助定义在利用蒸汽进行传热的系统内正确安装1型二次压力排水器（SPD）所需的信息。了解该标准后，可将其应用于此类系统，以提供有效且高效的冷凝水排放。这是蒸汽使用设备保持一致传热的必要功能。

The purpose of FCI 18-2-2020 is to help define the information required for proper installation of Type 1 Secondary Pressure Drainers (SPD) within systems utilizing steam for heat transfer. With an understanding of this criteria, it can be applied to these types of systems to provide effective and efficient condensate drainage. This is a necessary function of steam-using equipment to maintain consistent heat transfer.
