3.1
INSTALLATION
Install materials and equipment as indicated and in accordance with the
manufacturer's recommendations.
3.1.1
Excavation and Backfilling
Section 02300 EARTHWORK.
3.1.2
Corrosion Protection
Provide corrosion protection for buried steel piping in accordance with
Section 09974 PROTECTION OF BURIES STEEL PIPING AND STEEL BULKHEAD TIE RODS.
3.1.3
Piping
Provide Non-Destructive Examination (NDE) report for welding of piping.
Unless specifically stated to the contrary, fabrication, assembly, welding,
and brazing shall conform to ASME B31.1 for all piping of the air system.
Piping shall follow the general arrangement shown. Cut piping accurately
to measurements established for the work. Work piping into place without
springing or forcing, except where cold-springing is specified. Piping and
equipment within buildings shall be entirely out of the way of lighting
fixtures and doors, windows, and other openings. Locate overhead piping in
buildings in the most inconspicuous positions. Do not bury or conceal
piping until it has been inspected, tested, and approved. Where pipe
passes through building structure, pipe joints shall not be concealed, but
shall be located where they may be readily inspected and building structure
shall not be weakened. Avoid interference with other piping, conduit, or
equipment. Except where specifically shown otherwise, vertical piping
shall run plumb and straight and parallel to walls. Piping connected to
equipment shall be installed to provide flexibility for vibration.
Adequately support and anchor piping so that strain from weight of piping
is not imposed on the equipment.
