2. Does not melt
3. Diameter- .0114
4. Break Point – 35LBS
E. Construction:
1. Double sewn lock stitch with a minimum 4 to 6 stitches per inch. Jackets shall be sewn with two (2) parallel rows of stitching using thread in section 1.3D. The thread must be able to withstand the skin temperatures without degradation.
2. Hog rings, staples and wire are not are not acceptable methods of closure.
3. No raw cut jacket edges shall be exposed.
4. Jackets shall be fastened using hook and loop (Velcro) straps and 1” Slide Buckles.
5. All stitching will be done with thread in section 1.3D.
6. Provide a permanently attached Aluminum or stainless steel nameplate on each jacket to identify its location, size and tag number.
7. Provide a stainless steel or brass grommet at the low point of each jacket, in wet areas for moisture drain (on horizontal jackets as required).
8. The insulation shall be designed to minimize the convection current in the space between the hot metal surface and the inner layer of insulation. To this end, during jacket fabrication, the layers of insulating mat shall be placed in an overlapping pattern.
9. All jacket pieces which match mating seams must include an extended 2" flap constructed from the exterior fabric and shall be secured using hook & loop closure (i.e. Velcro TM) parallel to the seam.
10. Insulation must be sewn as integral part of the jacket to prevent shifting of the insulation.
11. Steam Trap and Steam Trap Station Jackets must be constructed in a box shape for removal and replacement inspection ease.
