Steam Trap Survey Inspection

Periodic ultrasonic steam trap survey to verify trap function, identify failed-open or failed-closed conditions, and estimate energy loss for maintenance prioritization.

Survey Identification

• Survey date and time recorded
• Facility, building, and system area identified
• Steam trap tag number or unique asset ID recorded
• Trap type identified
• Inspector name and qualification recorded
• Reference drawing, route, or asset list used

Operating Conditions

• Trap inlet pressure
• Trap outlet / return line pressure
• Steam pressure differential available across trap
• Upstream and downstream isolation valves in normal operating position
• Visible leakage, flashing, or abnormal discharge at trap station

Ultrasonic Evaluation

• Ultrasonic detector calibrated and functioning
• Listening point established at trap inlet
• Listening point established at trap outlet
• Trap operating condition
• Ultrasonic intensity or signal level
• Audible/ultrasonic pattern consistent with live steam leakage
• Condensate discharge observed or inferred

Energy Loss Estimate

• Estimated steam loss rate
• Estimated annual energy loss
• Priority ranking for repair
• Estimated impact on process or equipment performance

Corrective Action and Closeout

• Deficiency or non-conformance documented
• Corrective action assigned to maintenance owner
• Target repair date recorded
• Inspector sign-off
