C For the top used on the 48" turbine encloo sure, a 48" x 42" polyethylene adapter ring is required. If needed, refer to Section H for the optional adhesive kit (to bond the turbine enclosure to the containment collar) Sections 1, J, K and L for the field installed fitting kits (for electrical and plumbing connections to the turbine enclosure). G. Sealable Turbine Enclosure (Model STE–B Series) The sealable turbine enclosure is constructed of fiberglass rein- forced plastic. The sealable turbine enclo- sure is 42" or 48" diameter and can be bonded to the appropriate secondary con- tainment collar. The minimum length of the sealable turbine enclosure is two feet and the maximum is four feet: Sealable Turbine Model No. Enclosure Length STE426 -2 2' STE426 -3 31 STE42B -4 4. STE426 5 5 STE48B -2 2 STE48B -3 3' STE4sB -4 4. STE4813-5 51 Cut lines for field trimming are marked on the bottom 9 inches of the sealable turbine enclosure at three inch increments. The top and lid of the sealable turbine enclosure are constructed of fiberglass reinforced plastic. The oval lid opening (30" x 24") includes a 2" NPT threaded fitting (with steel fitting plug) for access to the sealable turbine enclosure without removing the lid. Refer to Section H for optional adhesive kits to bond the sealable turbine enclosure to the FRP top and the secondary containment collar; also refer to Section I for the optional field installed fitting kit, and Section J for the optional field installed electrical coupling kit (Kit EC -1). H.Turbine Enclosure Adhesive Kit (Kit -AD) When properly installed and cured, the adhesive kit provides a water tight seal to prevent the ingress of water. The adhesive kit includes In gallon of adhesive in a one gallon capacity can.The kit also includes catalyst (hardener), a wooden mixing stick, a three inch wide plastic putty knife, 60 grit sandpaper, and installation instructions. One adhesive kit is required for each turbine enclosure; the sealable turbine enclosure requires two kits. I. FRP Coupling Kit (Kit FC -3 or FC -4) is designed to interface with 3" or 4" nominal OD FRP pipe manu- factured by Ameron or Smith Fiberglass. The coupling ID is tapered at both ends. The two-piece coupling is constructed of fiberglass reinforced plastic and is field - installed using the supplied adhesive. Both pieces of the fitting are threaded together to hold the fitting in position while the adhesive cures. Kit FC -3 or Kit FC -4 includes one 3" or 4" nominal 1D FRP coupling, adhesive, catalyst (hardener), plastic mixing stick and applica- tor, 60 grit sandpaper, and installation instructions. The contractor must provide the hole saw (41r2 or 51a inch OD) or reciprocating saw to cut the hole in the turbine enclosure prior to installing the FRP coupling. 90. Tank Lifting Lugs Provide lifting lug(s) on all tanks. Lifting lug system shall be capable of withstanding weight of tank with a safety factor of 3:1. J. Electrical Coupling Kit Kit EC -1 is designed to interface with one inch steel electrical conduit. The two-piece coupling is constructed of steel and is field installed using the supplied adhesive. Both pieces of the fitting are threaded together to hold the fitting in position while the adhesive cures. Kit EC -1 includes two one inch steel cou- plings, adhesive catalyst (hardener), plastic mixing stick, 60 grit sandpaper, and installa- tion instructions. The contractor must provide a two inch hole saw or reciprocating saw to cut the hole in the turbine enclosure prior to installing the steel coupling. K. Secondary Containment Collar The secondary containment collar shall be constructed of fiberglass reinforced plastic. Collar shall be 42" or 48" in diameter and will be factory -installed in accordance with drawings. The collar will include a sensor mounting bracket. L. Containment Collar Sensor is pre - assembled and ready to wire. All electrical components must be U.L. listed or accept- ed. This float switch sensor is capable of detecting a 2" or more accumulation of liq- uid (water or product) in the turbine enclo- sure. The float switch is constructed of Buna-N; the float switch is housed in plastic casing and includes a mounting clamp. M. Ladders Shall be standard carbon steel supplied by the tank manufacturer. Refer todrawings for location. N. Heating Coils Shall be standard item as manufactured and/or supplied by the tank manufacturer including 22" manway. p. Probe Drawstring Nylon line shall be 150 Ib. break strength located at the monitoring fitting nearest the end of the tank. When a reservoir is located at this position, the drawstring shall be installed within the reservoir. Drawstring length will allow for a 7' tank burial depth. Q. Fittings Threaded — NPT 1. All threaded fittings on U.L. labeled tanks shall be located in a manway lid or a tank mount within 12" of the tank top center line and be constructed consistent with the requirements of the U.L. label. Fittings to be supplied with threaded cast iron plugs. 2. All standard threaded fittings to the prima- ry tank and monitoring cavity are 4" in diame- ter. The standard secondary containment cou- pling is 6" in diameter. All standard threaded fittings are half couplings. Reducers are to be used for smaller sizes where specified and provided by contractor. 3. Thread Standards — all threaded fittings ehall have machine tolerances in accordance with the ANSI standard for each fitting size. 4. Strength — Primary tank NPT fittings will withstand a minimum of 150 foot-pounds of torque and 1,000 foot-pounds of bending, both with 2:1 factor of safety. 5. Sizes Standard Reducer Sires Inlet 4' Outlet 4" Vent 4' Gauge 4` Fill 4` 6. Location —Refer to drawings for location. 7. Suction Line — Shall be installed on site by the contractor. Diameter of pipe and grade and schedule as called out in other sections. 8. Return Line — Shall be installed on the site by the contractor. Diameter of pipe and grade and schedule as called out in other sections. 9. All rigid internal piping shall be terminated at least 4" from the bottom of the tank. 3.01, 3.02 Installation And Testing Tanks shall be tested and installed according to the current installation instructions provided with the tank (refer to Fluid Containment Pub. No. 6304 and include as part of your specification). 27
