prevent vibrations from transmitting from equipment to the piping system. Expansion loops,
expansion joints and offsets shall provide with adequate anchors and guides where required to
prevent excessive forces within the piping systems. All piping shall be properly and adequately
supported. Pipe supports shall conform to MSS SP-58 and MSS SP-69.
10-13.1
Chilled water. Shall be steel piping conforming to ASTM A 53/A 53M, Grade A or B,
black steel, schedule 40 or copper tubing conforming to ASTM B 88, ASTM B 88M, Type K or L.
10-13.2
Hot water. Shall be steel piping conforming to ASTM A 53/A 53M, Type E or S,
Grade A or B, black steel, schedule 40 or copper tubing conforming to ASTM B 88, ASTM B
88M, Type K or L.
10-13.3
Refrigerant. Copper tubing shall conform to ASTM B 280 annealed or hard drawn as
required. Copper tubing shall be soft annealed where bending is required and hard drawn
where no bending is required. Soft annealed copper tubing shall not be used in sizes larger
than 35 mm. Refrigerant piping, valves, fittings, and accessories shall conform to the
requirements of ASHRAE 15.
10-13.4
Steam. Shall be steel piping conforming to ASTM A 53/A 53 M, Type E or S, Grade
A, black steel, schedule 40.
10-13.5
Steam condensate. Shall be steel piping conforming to ASTM A 53/A 53 M, Type E
or S, Grade A, black steel, schedule 80.
10-13.6
Condensate drain. Shall be copper tubing or PVC pipe.
10-14
INSULATION. Pipe and duct insulation shall be in accordance with ASHRAE 90.1.
Equipment insulation shall be a minimum of 50 mm thickness or as necessary to prevent the
surface temperature from exceeding 60 degrees C. Thermal insulation on piping, fittings,
ductwork, equipment and vessels shall be installed per the "National Commercial & Industrial
Insulation Standards" (MICA) Manual. The sample specification format in Section VI of the
MICA manual shall be used and edited to suit the work to be performed.
10-14.1
Duct insulation. Provide on the exterior of all supply and outside air ducts and
plenums and on all return ducts in unconditioned spaces. Exhaust ductwork does not require
insulation. Insulation shall be faced with a vapor barrier material having a performance rating
not to exceed 1.0 perm. Insulation, vapor barrier, and closure systems shall be
non-combustible as defined in NFPA 255, with a flame-spread rating of not more than 25, and a
smoke development rating of not more than 50, as defined in ASTM E-84. Where insulated
ducts pass through fire walls, fire partitions, above grade floors, and fire rated chase walls, the
penetration shall be sealed with fire stopping materials.
