SAMSON OCEANFRONT PARK <br />CITY OF SUNNY ISLES <br />TECHNICAL SPECIFICATIONS <br /> <br /> PLUMBING PIPING INSULATION 15085-9 <br /> <br /> <br /> <br />3.05 <br /> <br />INSTALLATION OF CELLULAR-GLASS INSULATION: <br />A. Insulation Installation on Straight Pipes and Tubes: <br />1. Secure each layer of insulation to pipe with wire or bands and tighten bands without <br /> deforming insulation materials. <br />2. Where vapor barriers are indicated, seal longitudinal seams, end joints, and protrusions with <br /> vapor-barrier mastic and joint sealant. <br />3. For insulation with factory-applied jackets on above-ambient services, secure laps with <br /> outward clinched staples at 6 inches <br />4. For insulation with factory-applied jackets on below-ambient services, do not staple <br /> o.c. <br /> longitudinal tabs. Instead, secure tabs with additional adhesive as recommended by insulation <br /> material manufacturer and seal with vapor-barrier mastic and flashing sealant. <br /> <br />B. Insulation Installation on Pipe Flanges: <br />1. Install preformed pipe insulation to outer diameter of pipe flange. <br />2. Make width of insulation section same as overall width of flange and bolts, plus twice the <br /> thickness of pipe insulation. <br />3. Fill voids between inner circumference of flange insulation and outer circumference of <br /> adjacent straight pipe segments with cut sections of cellular-glass block insulation of same <br /> thickness as pipe insulation. <br />4. Install jacket material with manufacturer’s recommended adhesive, overlap seams at least 1 <br /> inch <br /> <br />, and seal joints with flashing sealant. <br />C. Insulation Installation on Pipe Fittings and Elbows: <br /> <br />1. Install preformed sections of same material as straight segments of pipe insulation when <br /> available. Secure according to manufacturer’s written instructions. <br />2. When preformed sections of insulation are not available, install mitered sections of cellular- <br /> glass insulation. Secure insulation materials with wire or bands. <br /> <br />D. Insulation Installation on Valves and Pipe Specialties: <br />1. Install preformed sections of cellular-glass insulation to valve body. <br />2. Arrange insulation to permit access to packing and to allow valve operation without <br /> disturbing insulation. <br />3. Install insulation to flanges as specified for flange insulation application. <br /> <br />3.06 <br /> <br />INSTALLATION OF FLEXIBLE ELASTOMERIC INSULATION: <br />A. Seal longitudinal seams and end joints with manufacturer’s recommended adhesive to eliminate <br /> openings in insulation that allow passage of air to surface being insulated. <br /> <br />B. Insulation Installation on Pipe Flanges: <br />1. Install pipe insulation to outer diameter of pipe flange. <br />2. Make width of insulation section same as overall width of flange and bolts, plus twice the <br /> thickness of pipe insulation. <br />3. Fill voids between inner circumference of flange insulation and outer circumference of <br /> adjacent straight pipe segments with cut sections of sheet insulation of same thickness as pipe <br /> insulation. <br />4. Secure insulation to flanges and seal seams with manufacturer’s recommended adhesive to <br /> eliminate openings in insulation that allow passage of air to surface being insulated. <br /> <br />C. Insulation Installation on Pipe Fittings and Elbows: <br />1. Install mitered sections of pipe insulation. <br />2. Secure insulation materials and seal seams with manufacturer’s recommended adhesive to <br /> eliminate openings in insulation that allow passage of air to surface being insulated.
