F. Construction:
- Sewn with lock stitch at a minimum of 4 to 6 stitches per inch. Jackets shall be sewn using specified thread in section 1.3D. The thread must be able to withstand the skin temperatures without degradation.
- Hog rings, staples and wire are not acceptable methods of closure.
- No raw cut jacket edges shall be exposed after install.
- Jackets shall be fastened using a combination of hook and loop (i.e., Velcro®), straps, and D-rings depending on application temperature.
- The insulation shall be designed to minimize the convection current in the space between the hot metal surface and the inner layer of insulation.
- All jacket pieces which match mating seams must include an extended 2″ flap constructed from the exterior fabric (or equivalent) and shall be secured using hook & loop closure (i.e., Velcro®) parallel to the seam or straps and/or D-Rings depending on application temperature.
- Insulation shall be sewn as integral part of the jacket to prevent shifting of the insulation. Insulation pins are NOT an allowable method of preventing the insulation from shifting and shall NOT be used.
- Steam Trap Jackets must be constructed in a box shape for removal and replacement inspection ease.
G. Identification, Labelling, and Management:
- Provide a permanently attached Laser Etched Anodized Aluminum nameplate (2” x 3.5”) SLATE tag on each jacket to identify its location and item number. Each nameplate must have a Laser Etched QR code linking to a website that contains the following information about each individual jacket:
- Item Number
- Location Details
- Application Type
- Operating Pressure
- Component Type
- Component Size
- Jacket Min and Max Temp
- Insulation Thickness
- ANSI Class or NPT
- Install Date
- Install Photo
- Component Maintenance History
- Jacket O&M History
- A Smartphone App (iOS or Android) must be submitted, and training provided, upon project completion to display the website and items listed in section 5 above.
- O&M: A Smartphone App (iOS or Android) must be used to perform required O&M maintenance tasks. Items listed in section 1 above must be displayed when the QR code on the jacket is scanned. In addition, the date of the O&M inspection along with a new photo must be displayed.
H. Measurement and Verification (M&V):
- Provide Measurement and Verification for Pipe insulation and Removable Jacket insulation using Smart Sensors manufactured by THERMAXX, 14 Farwell Street, Bldg. 2B, West Haven, CT 06516. Sensors will be placed on insulation, with predetermined quantities and locations, providing a sampling of the insulated components. One sensor on each process type (steam, hot water, condensate, etc.) is required in each area. Sensors will be removed after 12 months.
- Sensors shall include:
- • IP67 Rated Enclosure (dust tight & water resistant)
- • Battery powered operation
- • Wireless communication to Gateway
- • Minimum of two independent temperature probes capable
- of reading temperatures up to 250°F
- • Minimum of one independent temperature probe capable
