What is typically installed in the inlet line of a steam trap?

The installation of a steam strainer in the inlet line of a steam trap is crucial for maintaining the efficiency and reliability of the system. Steam strainers serve to filter out debris, dirt, and other contaminants from the steam before it enters the trap. This is important because any foreign particles can cause blockages or wear on the moving parts within the steam trap, which can lead to malfunctions or failures. By ensuring that the steam is free from contaminants, a strainer helps prolong the life of the steam trap and maintains its proper functioning.

In contrast, a pressure gauge, flow control valve, or thermostat serve different purposes in a steam system. A pressure gauge measures pressure levels, a flow control valve regulates the flow of steam, and a thermostat controls temperature but does not filter contaminants. Each of these components may be necessary in various parts of a steam system, but they do not fulfill the specific role that a steam strainer provides in protecting the trap from impurities.
