Construction Documents 20033 Orange County Europa Center 21 0500.01 - 6 COMMON WORK RESULTS FOR FIRE SUPPRESSION 17.Aboveground, Exterior-Wall Pipe Penetrations: Seal penetrations using sleeves and mechanical sleeve seals. Select sleeve size to allow for 1-inch (25-mm) annular clear space between pipe and sleeve for installing mechanical sleeve seals. a.Install steel pipe for sleeves smaller than 6 inches (150 mm) in diameter. b.Install cast-iron "wall pipes" for sleeves 6 inches (150 mm) and larger in diameter. c.Mechanical Sleeve Seal Installation: Select type and number of sealing elements required for pipe material and size. Position pipe in center of sleeve. Assemble mechanical sleeve seals and install in annular space between pipe and sleeve. Tighten bolts against pressure plates that cause sealing elements to expand and make watertight seal. 18.Underground, Exterior-Wall Pipe Penetrations: Install cast-iron "wall pipes" for sleeves. Seal pipe penetrations using mechanical sleeve seals. Select sleeve size to allow for 1-inch (25-mm) annular clear space between pipe and sleeve for installing mechanical sleeve seals. a.Mechanical Sleeve Seal Installation: Select type and number of sealing elements required for pipe material and size. Position pipe in center of sleeve. Assemble mechanical sleeve seals and install in annular space between pipe and sleeve. Tighten bolts against pressure plates that cause sealing elements to expand and make watertight seal. 19.Fire-Barrier Penetrations: Maintain indicated fire rating of walls, partitions, ceilings, and floors at pipe penetrations. Seal pipe penetrations with firestop materials. Refer to Division 07 Section "Penetration Firestopping" for materials. 20.Verify final equipment locations for roughing-in. 21.Refer to equipment specifications in other Sections of these Specifications for roughing-in requirements. D.PIPING JOINT CONSTRUCTION 1.Join pipe and fittings according to the following requirements and Division 21 Sections specifying piping systems. 2.Ream ends of pipes and tubes and remove burrs. Bevel plain ends of steel pipe. 3.Remove scale, slag, dirt, and debris from inside and outside of pipe and fittings before assembly. 4.Soldered Joints: Apply ASTM B 813, water-flushable flux, unless otherwise indicated, to tube end. Construct joints according to ASTM B 828 or CDA's "Copper Tube Handbook," using lead-free solder alloy complying with ASTM B 32. 5.Brazed Joints: Construct joints according to AWS's "Brazing Handbook," "Pipe and Tube" Chapter, using copper-phosphorus brazing filler metal complying with AWS A5.8. 6.Threaded Joints: Thread pipe with tapered pipe threads according to ASME B1.20.1. Cut threads full and clean using sharp dies. Ream threaded pipe ends to remove burrs and restore full ID. Join pipe fittings and valves as follows: a.Apply appropriate tape or thread compound to external pipe threads unless dry seal threading is specified. b.Damaged Threads: Do not use pipe or pipe fittings with threads that are corroded or damaged. Do not use pipe sections that have cracked or open welds. 7.Welded Joints: Construct joints according to AWS D10.12, using qualified processes and welding operators according to Part 1 "Quality Assurance" Article. 8.Flanged Joints: Select appropriate gasket material, size, type, and thickness for service application. Install gasket concentrically positioned. Use suitable lubricants on bolt threads. 9.Plastic Piping Solvent-Cement Joints: Clean and dry joining surfaces. Join pipe and fittings according to the following: a.Comply with ASTM F 402 for safe-handling practice of cleaners, primers, and solvent cements. b.CPVC Piping: Join according to ASTM D 2846/D 2846M Appendix. 10.Plastic Pressure Piping Gasketed Joints: Join according to ASTM D 3139.
