A steam trap is a type of automatic valve that filters out condensed steam (or condensate) and non-condensable gases such as air without letting steam escape.
A steam trap’s primary function is to maximize a system's heating efficiency by trapping steam within the piping system, ensuring that it does not leave without losing all its heat to the main process fluid.
Steam traps are commonly used in industrial applications that utilize steam, such as power generation.
A steam trap symbol in P&ID is a graphical representation of the component, providing a close approximation of its position within a piping system without the need for a physical inspection.
It is portrayed as a capital T surrounded by a square box.
