PART 3 - EXECUTION 3.01 PIPING SYSTEM EXAMINATION A. Examine piping systems for compliance with requirements for installation tolerances and other conditions affecting performance. 1. Proceed with installation only after unsatisfactory conditions have been corrected. COCA-COLA NORTH AMERICA JOB NO. 7588.20 ISSUED: 070910 LINE ADDITIONS NORTHAMPTON, MASSACHUSETTS PLUMBING BASIC PIPING MATERIALS AND METHODS 220505 - 3 of 5 B. Examine each valve, strainer, and other pipe specialties and components interior for cleanliness, freedom from foreign matter, and corrosion. Remove special packing materials, such as blocks, used to prevent disc movement during shipping and handling. C. Operate valves in positions from fully open to fully closed. Examine guides and seats made accessible by such operations. D. Examine threads on valves, strainers, and other pipe specialties and components, and mating pipe for form and cleanliness. E. Examine mating flange faces for conditions that might cause leakage. Check bolting for proper size, length, and material. Verify that gasket is of proper size, that its material composition is suitable for service, and that it is free from defects and damage. F. Do not attempt to repair defective valves, strainers, and other pipe specialties and components; replace with new valves, strainers, and specialties. 3.02 PIPE SLEEVE AND ESCUTCHEON APPLICATIONS A. Refer to the “Plumbing Hanger and Support Material Schedule” on the drawings for pipe sleeve and escutcheon material applications. 3.03 PIPING INSTALLATION A. Install piping according to the following requirements and Division 22 Sections specifying piping systems. B. General Locations and Arrangements: Drawings (plans, schematics, and diagrams) indicate the general location and arrangement of the piping systems. Location and arrangement of piping layout take into consideration pipe sizing and friction loss, expansion, pump sizing, and other design considerations. Installation work will follow as closely as possible all piping-detail drawings and specifications. If deviations from any of the drawings or specifications are necessary, they will be done only WITH PRIOR APPROVAL by Architect/Engineer C. Install groups of pipes parallel to each other, spaced to permit applying insulation and servicing of valves. D. Install piping in concealed locations, unless otherwise indicated and except in equipment rooms, shafts, tunnels, service areas, and as follows: 1. All pipe installations in GMP areas shall be exposed to view (unless indicated to be concealed). E. Install piping at right angles or parallel to building walls. Diagonal runs are prohibited unless specifically indicated otherwise. COCA-COLA NORTH AMERICA JOB NO. 7588.20 ISSUED: 070910 LINE ADDITIONS NORTHAMPTON, MASSACHUSETTS PLUMBING BASIC PIPING MATERIALS AND METHODS 220505 - 4 of 5 F. Install piping above accessible ceilings to allow sufficient space for ceiling panel removal. G. Install piping to permit valve servicing. H. Install piping at indicated slopes. I. Install piping free of sags and bends. J. Provide fittings for changes in direction and branch connections. K. Install piping tight to slabs, beams, joists, columns, walls, and other permanent elements of the building, unless indicated otherwise on the drawings. Provide space to permit insulation applications, with minimum 1-inch clearance outside the insulation. Allow sufficient space above removable ceiling panels to allow for panel removal. L. Provide pipe sleeves at cold storage panel wall/ceiling penetrations as detailed on the drawings. M. Provide pipe sleeves for pipes passing through concrete and masonry interior walls and concrete floor and roof slabs. 1. Cut pipe sleeves to length for mounting flush with both surfaces. a. Exception: Extend pipe sleeves installed in floors of mechanical equipment areas or other wet areas 2 inches above finished floor level. 2. Install pipe sleeves in new walls and slabs as new walls and slabs are constructed. 3. Install pipe sleeves that are large enough to provide 1/4-inch annular clear space between sleeve and pipe or pipe insulation. 4. Seal annular space between pipe sleeves through non-rated interior walls and floors and pipe or pipe insulation, using joint sealants appropriate for size, depth, and location of joint. Refer to Division 07 Section “Joint Sealants” for materials and installation. N. Install escutcheons at wall, floor, and ceiling penetrations in exposed finished locations and within cabinetry as follows: 1. Provide one-piece escutcheons for new piping. 2. Provide two piece split type escutcheons for existing piping.
