EXECUTION

3.1 PIPING

A. General

1. Remove foreign materials before erection. Ream ends of piping to remove burrs.

2. Install piping parallel to building walls and ceilings and at such heights not to obstruct any portion of window, doorway, stairway, or passageway. Install piping to allow adequate service space for equipment. Refer to drawings and/or manufacturer's recommendations. Install vertical piping plumb. Where interferences develop in field, offset or reroute piping as required to clear such interferences. In all cases, consult drawings for exact location of pipe spaces, ceiling heights, door and window openings or other architectural details before installing piping.

3. Provide anchors, expansion joints, swing joints and expansion loops so that piping may expand and contract without damage to itself, equipment or building.

REHABILITATE SCHOODIC WATER AND WASTEWATER SYSTEMS 23 1214 - 10

4. Mitered ells, welded branch connections, notched tees and "orange peel" reducers are not allowed. Unless specifically indicated, reducing flanges and reducing bushings are not allowed. Reducing bushings may be used for air vents and instrumentation connections.

5. Do not install piping over electrical panelboards, switchgear, switchboards or motor control centers.

6. Install valves, control valves and piping specialties, including items furnished by others, as specified and/or detailed. Make connections to all equipment installed by others where that equipment requires piping services indicated in this Section.

7. For underground piping, install piping in accordance with PEI RP100-11 and in accordance with manufacturer’s written recommendations and instructions. Take specific care to comply with bedding, backfill, separation and slope requirements.

Install metallic detection tape above nonmetallic piping per Section 20 0553 and note exact routing (and depth) on as-built drawings.

B. Threaded Pipe Joints

1. Threads of pipe and fittings shall conform to ASME B1.20.1.

2. Cut threads so that no more than 3 threads remain exposed after joint is made. Ream pipe ends after cutting and clean before erection. Apply thread sealants to cleaned male threads. Assemble joint to appropriate depth and remove any excess pipe joint compound from tightened joint.

C. Flanged Joints

1. Clean flange surfaces and align flange surfaces parallel. Bolt holes of gaskets shall be cut slightly larger than bolt diameter and gasket ID shall be slightly larger than flange ID.

2. Position gasket concentrically so compression is equally distributed over entire gasket surface.

3. Lubricate bolts and run nuts down by hand.

4. By using torque wrench, tighten nuts in the proper sequence so gasket is compressed evenly, and to the appropriate torque specified by bolt manufacturer.

5. Re-torque bolts 12 to 24 h after start-up.

D. Liquid Propane (Fill, Vent, Gauge and Aboveground Supply and Return)

1. Install supply, return, fill, vent and gauge lines where indicated, including flexible connections and other piping specialties included with equipment furnished by others. Solder-joints and unions with gaskets or packing are not allowed. Pitch horizontal piping at minimum 1/8" per foot down to tank.

2. Provide double or triple swing joints in pipe lines connected to underground tanks, except straight fill lines and test wells, to permit tanks to settle without impairing tightness of pipe connections.

3. Install flexible piping connections in supply and return lines at each diesel engine.

Return line from each engine to main oil tank or day tank to contain no manual or automatic valves to restrict flow; pressure relief valves are acceptable.

REHABILITATE SCHOODIC WATER AND WASTEWATER SYSTEMS 23 1214 - 11

4. For supply or suction piping serving multiple fuel consuming devices, install shut-off valves to isolate each devise for maintenance.

5. Terminate oil tank fill piping at least 2 ft from any building wall. Install vent pipe to drain toward tank without sags or traps in which liquid may collect.

6. Terminate vent pipes outside of building, not less than 2 ft measured vertically or horizontally from any building opening, not less than 25 ft from any outside air intake, and with weather-proof and flame-proof vent cap or hood.
