A steam system that has not been maintained for a period of time will have a significant number of steam traps that have failed. Approximately twenty percent of the steam leaving a central boiler plant is lost via leaking traps in a typical space heating system without a proper PdM program in place. A routine PdM program should be implemented to detect any waste of energy, efficiency, and dollars. Implementing any type of steam trap maintenance program will be beneficial and the selection of the assessment equipment is of secondary importance.
Using ultrasonic or thermal imaging testing equipment our service technicians conduct a steam trap survey to detect plugged, leaking, or blowing steam traps. Thermal imaging is used to identify completely failed traps and traps which perform in a borderline manner. Ultrasonic instruments are used in conjunction with thermal imaging to further define the problem as required. Upon detection, the bad trap location is recorded digitally and with a detailed report.
