How to Diagnose a Steam Trap Failure

Steam traps are wonderful tools, helping regulate piping systems and heat exchangers for long life and maximum efficiency. But steam traps, like all mechanical systems, can fail–resulting in dangerous conditions and major increases in cost. Line debris and scale can jam up a steam trap, sealing steam in or disrupting the moving pieces. Water hammer (a dangerous condition caused when water is carried along a steam line) can dent, bend, or even break fragile parts. Freezing conditions can clog or even destroy a steam trap. It’s essential that operators and maintenance personnel know how to recognize these failures, so the problem can be fixed promptly and safely.
