The report states, “They also determined the direct and root cause of these events was an equipment/material problem (defective or failed part) because valves and steam traps were not operating as designed.” The engineers reviewed the steam trap design and decided to replace the existing ‘bucket’ style steam traps with newer, more effective ‘orifice’ traps. The new trap is designed to drain condensate continuously and completely. These traps have no internal moving parts, which will greatly reduce trap maintenance. The new traps were installed with a special 40-mesh stainless steel strainer insert to trap any particles or contaminants before they reach the drain nozzle.
