Steam Management Inc. conducted a comprehensive analysis to identify and catalog all steam traps in operation within pipe distribution and terminal heating units. The data collected was utilized to develop a scope of work encompassing the following improvements:

• Repair/Replacement of Failed Steam Traps

  • We utilized ultrasound and visual observations to test and analyze steam trap operations.

• Recommended the replacement of 56 existing F&T and Inverted Bucket steam traps. The scope of work includes replacing other components associated with the steam trap station such as strainers, valves, and fittings that do not meet the VHA directive requirements.

• Savings are realized by identifying failures much sooner than traditional annual testing. Annual maintenance testing operating expenses typically offset the program investment required to operate and maintain the data analytics services. As a basis to estimated savings, steam traps in operation were tested to determine an overall failure rate. 56 traps were found failed as a result of testing. The approximate annual losses through traps is 7,264 Mlbs/year.

• Continuous Steam Trap Monitoring System:

• Steam trap testing is a critical maintenance function of efficient steam system operation. Performing annual testing identifies failures and losses within the system. However, to prevent losses when they occur, continuous monitoring is necessary. This level of visibility into the operational status of the steam trap population is critical to the efficient operation of your steam system. Continuous monitoring will allow for a responsive maintenance program addressing the failures as they happen.

• install a continuous steam trap monitoring system and associated wireless network to collect data and back haul it to a cloud-based dashboard. System shall include: 290 steam ultrasonic trap monitors and 8 gateways to ensure continuous monitoring. Gateways provide wireless LoRaWan data connectivity, with internet access through cellular or wired ethernet connections.

• Steam Management, Inc will provide turnkey installation and setup of the steam trap monitoring system and dashboard. This includes:

1. Data verification of steam trap schedule

2. Hardware selection and calibration

3. Monitor and gateway installation

4. Dashboard setup, training, and quarterly dashboard review

5. System commissioning

6. Analytics and notifications

7. Annual subscription shall include 1 onsite warranty/troubleshooting visit

8. Gateways shall be hardwired into a 120VAC power supply (electrical provided by VA facilities)

• Insulation of Uninsulated Piping and Equipment:

• The insulation audit was performed by our team using an in-house developed mobile application.  Infrared readings were taken at representative locations and are used for the savings calculation. In all, 178 locations were identified for a potential efficiency increase of 2,298 MMBtu per year. Installing insulation on bare surfaces will reduce heat loss and lower the temperature of the space.

• Installation of fiberglass insulation with all-service jacketing and removable insulation covers (RICs) on various valves and equipment.
