INDIAN RIVER COUNTY JULY 25, 2014 <br />INTERGENERATIONAL RECREATION CENTER 100% CONSTRUCTION DOCUMENTS <br />3.2 PREPARATION <br />A. Surface Preparation: Clean and dry surfaces to receive insulation. <br />adversely affect insulation application. <br />B. Surface Preparation: Clean and prepare surfaces to be insulated. <br />corrosion coating to insulated surfaces as follows: <br />Remove materials that will <br />Before insulating, apply a <br />Carbon Steel: Coat carbon steel operating at a service temperature between 32 and 300 <br />deg F with an epoxy coating. Consult coating manufacturer for appropriate coating <br />materials and application methods for operating temperature range. <br />C. Mix insulating cements with clean potable water; if insulating cements are to be in contact with <br />stainless-steel surfaces, use demineralized water. <br />3.3 <br />A. <br />GENERAL INSTALLATION REQUIREMENTS <br />Install insulation materials, accessories, and finishes with smooth, straight, and even surfaces; <br />free of voids throughout the length of equipment and piping including fittings, valves, and <br />specialties. <br />B. Install insulation materials, forms, vapor barriers or retarders, jackets, and thicknesses required <br />for each item of equipment and pipe system as specified in insulation system schedules. <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 <br />dry state. <br />D. Install insulation with longitudinal seams at top and bottom of horizontal runs. <br />E. Install multiple layers of insulation with longitudinal and end seams staggered. <br />F. Do not weld brackets, clips, or other attachment devices to piping, fittings, and specialties. <br />G. Keep insulation materials dry during application and finishing. <br />H. Install insulation with tight longitudinal seams and end joints. Bond seams and joints with <br />adhesive recommended by insulation material manufacturer. <br />I. Install insulation with least number of joints practical. <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 <br />legs from point of attachment to supported item to point of attachment to structure. Taper <br />and seal 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 <br />material 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 />PLUMBING INSULATION 220700 - 6 <br />
