SECTION 033000 - CAST-IN-PLACE CONCRETE

Sludge Treatment Project Engineered Container Retrieval and Transfer System January 2012
1. Outer Jacket: Filament wound, polyester resin/fiberglass reinforcement composite
directly applied on the insulating foam. The manufacturer shall have the option to
filament wind fiberglass directly onto the polyurethane foam or inject foam into a
fiberglass outer casing. The minimum thickness of the jacket shall be 0.055 inches.
2. Carrier Pipe: ASTM A53/A 53M, Grade B, Schedule 40, black steel pipe, wrought steel
fittings and forged-steel flanges and welded and flanged joints.
3. Insulation: Polyurethane foam completely filling annular space between carrier pipe and
outer jacket to a minimum thickness of 1". In-place density shall be 1.9 to 2.1 0.16
BTU/(hr.) (sq. ft.)°F./in.) at 73° F., and a closed cell content of 90% to 95%. Exposed
insulation at unit ends shall be sealed with factory-applied end seal
2.3 JOINING MATERIALS
