Refer to equipment specifications in <br />requirements. <br />JULY 25, 2014 <br />100% CONSTRUCTION DOCUMENTS <br />other Sections of these Specifications for roughing -in <br />3.2 PIPING JOINT CONSTRUCTION <br />A. Join pipe and fittings according to the following requirements and Division 22 Sections <br />specifying piping systems. <br />B. Ream ends of pipes and tubes and remove burrs. <br />C. Remove scale, slag, dirt, and debris from inside and outside of pipe and fittings before <br />assembly. <br />D. Soldered Joints: Apply ASTM B 813, water-flushable flux, unless otherwise indicated, to tube <br />end. Construct joints according to ASTM B 828 or CDA's "Copper Tube Handbook," using lead- <br />free solder alloy complying with ASTM B 32. <br />Threaded Joints: Thread pipe with tapered pipe threads according to ASME B1.20.1. Cut <br />threads full and clean using sharp dies. Ream threaded pipe ends to remove burrs and restore <br />full ID. Join pipe fittings and valves as follows: <br />1. Apply appropriate tape or thread compound to external pipe threads unless dry seal <br />threading is specified. <br />2. Damaged Threads: Do not use pipe or pipe fittings with threads that are corroded or <br />damaged. Do not use pipe sections that have cracked or open welds. <br />F. Flanged Joints: Select appropriate gasket material, size, type, and thickness for service <br />application. Install gasket concentrically positioned. Use suitable lubricants on bolt threads. <br />G. Plastic Piping Solvent -Cement Joints: Clean and dry joining surfaces. Join pipe and fittings <br />according to the following: <br />Comply with ASTM F 402 for safe -handling practice of cleaners, primers, and solvent <br />cements. <br />PVC Nonpressure Piping: Join according to ASTM D 2855. <br />3.3 PIPING CONNECTIONS <br />A. <br />Make connections according to the following, unless otherwise indicated: <br />1. Install unions, in piping NPS 2 and smaller, adjacent to each valve and at final connection <br />to each piece of equipment. - <br />2. Wet Piping Systems: Install dielectric coupling and nipple fittings to connect piping <br />materials of dissimilar metals. <br />3.4 EQUIPMENT INSTALLATION - COMMON REQUIREMENTS <br />A. Install equipment to allow maximum possible headroom unless specific mounting heights are <br />not indicated. <br />B. Install equipment level and plumb, parallel and perpendicular to other building systems and <br />components in exposed interior spaces, unless otherwise indicated. <br />COMMON WORK RESULTS FOR PLUMBING 220500 - 6 <br />
