SAMSON OCEANFRONT PARK <br />CITY OF SUNNY ISLES <br />TECHNICAL SPECIFICATIONS <br /> <br /> PLUMBING PIPING INSULATION 15085-6 <br /> <br /> <br /> <br />3.02 <br /> <br />GENERAL INSTALLATION REQUIREMENTS: <br />A. Install insulation materials, accessories, and finishes with smooth, straight, and even surfaces; free <br /> of voids throughout the length of piping including fittings, valves, and specialties. <br /> <br />B. Install insulation materials, forms, vapor barriers or retarders, jackets, and thicknesses required for <br /> each item of pipe system as specified in insulation system schedules. <br /> <br />C. Install accessories compatible with insulation materials and suitable for the service. Install <br />accessories that do not corrode, soften, or otherwise attack insulation or jacket in either wet or dry <br />state. <br /> <br />D. Install insulation with longitudinal seams at top and bottom of horizontal runs. <br /> <br />E. Install multiple layers of insulation with longitudinal and end seams staggered. <br /> <br />F. Do not weld brackets, clips, or other attachment devices to piping, fittings, and specialties. <br /> <br />G. Keep insulation materials dry during application and finishing. <br /> <br />H. Install insulation with tight longitudinal seams and end joints. Bond seams and joints with <br /> adhesive recommended by insulation material manufacturer. <br /> <br />I. Install insulation with least number of joints practical. <br /> <br />J. Where vapor barrier is indicated, seal joints, seams, and penetrations in insulation at hangers, <br /> supports, anchors, and other projections with vapor-barrier mastic. <br />1. Install insulation continuously through hangers and around anchor attachments. <br />2. For insulation application where vapor barriers are indicated, extend insulation on anchor legs <br />from point of attachment to supported item to point of attachment to structure. Taper and seal <br />ends at attachment to structure with vapor-barrier mastic. <br />3. Install insert materials and install insulation to tightly join the insert. Seal insulation to <br /> insulation inserts with adhesive or sealing compound recommended by insulation material <br /> manufacturer. <br />4. Cover inserts with jacket material matching adjacent pipe insulation. Install shields over <br /> jacket, arranged to protect jacket from tear or puncture by hanger, support, and shield. <br /> <br />K. Apply adhesives, mastics, and sealants at manufacturer's recommended coverage rate and wet and <br /> dry film thicknesses. <br /> <br />L. Install insulation with factory-applied jackets as follows: <br />1. Draw jacket tight and smooth. <br />2. Cover circumferential joints with 3-inch- <br /> Secure strips with adhesive and outward clinching staples along both edges of strip, spaced <br />wide strips, of same material as insulation jacket. <br />4 <br /> inches <br />3. Overlap jacket longitudinal seams at least <br /> o.c. <br />1-1/2 inches <br /> seams at bottom of pipe. Clean and dry surface to receive self-sealing lap. Staple laps with <br />. Install insulation with longitudinal <br /> outward clinching staples along edge at 2 inches <br />a. For below-ambient services, apply vapor-barrier mastic over staples. <br /> o.c. <br />4. Cover joints and seams with tape, according to insulation material manufacturer's written <br /> instructions, to maintain vapor seal. <br />5. Where vapor barriers are indicated, apply vapor-barrier mastic on seams and joints and at <br /> ends adjacent to pipe flanges and fittings. <br /> <br />M. Cut insulation in a manner to avoid compressing insulation more than 75 percent of its nominal
