General
The system shall be manufactured to allow for the placement of
leak detection equipment. The containment shall be drainable and air testable.
All components of the containment system, including pipe, fittings, leak
detection equipment, containment boxes and floor drains, shall be supplied
by Flo-Safe, Inc. The containment piping shall be joined by two piece hinged
fittings with gasket seals, secured with stainless steel pressure bands
and thermoplastic pins. The split fittings shall be reusable.
Materials
All pipe and
fittings shall be clear PVC or polypropylene (PP) and supplied by the same
manufacturer. Gasket material shall be EPDM and be a continuous, one-piece
molded component for each half fitting. Pressure bands shall be stainless
steel. No glues, epoxies, or other foreign materials shall be allowed for
joining purposes.
Pipe Support
Spacing shall
be determined by the manufacturer based on pipe diameters, pipe materials
and operating temperatures of the product pipe. In all cases, pipes within
the secondary containment pipe shall be supported at not more than 10 ft.
intervals. These supports shall be designed for continuous air flow and
drainage of the secondary containment in place.
Installation
The installing
contractor shall install the system in accordance with the directions furnished
by the manufacturer and as approved by the architect and engineer. Installation
instructions and an installation video shall be provided to the installing
contractor by the manufacturer prior to installation.
Testing
An air test,
using test equipment supplied by the manufacturer, shall be conducted after
installation. The test shall not exceed 5 psi and shall not exceed 1 hour
in duration. All manufacturer's test instructions shall be followed.
Backfill
A 4 inch layer
of sand or fine gravel shall be placed and tamped in the trench to provide
a uniform bedding for the containment pipe. The entire trench shall be
evenly backfilled with a similar material as the bedding in 6 inch compacted
layers to a minimum of 6 inches above the top of the piping system. The
remaining trench shall be evenly and continuously backfilled in uniform
layers with suitable excavated soil.
