Primary Tank
- HDLPE, 1.9 SpGr, Natural color (ASTM D-1998 - 600 psi hoop stress design)
-
Outdoors - HDLPE, 1.9 SpGr, Opaque White Resin #880059
Secondary Containment
Tank - HDLPE, 1.5 SpGr, Natural color
- Fittings:
- Material of Construction: Fitting: PVC or CPVC (schedule
80), Gasket: Viton®,Bolt: Titanium
- Plumbing To The Tank:
- Required use of flexible connections with
fittings
Allows for 4% lateral and vertical expansion and contraction of the tank
Reduces pump and piping vibration stress on the tank, fittings, and gaskets
Flexible connections, piping, and valves must have structural support independent
of tank sidewall and dome
- Venting:
- Tanks are designed for use at atmospheric pressure.
Pressure or vacuum situation can cause excessive deformation or damage to the tanks
and void warranty. Venting equipment should be sized to limit pressure or vacuum
in the tank to a maximum of ½” water column (0.018 PSI). If the tank will be pneumatically
filled (through tanker discharge) additional pressure relief may be required.
- Foundation and Restraints:
- Tanks should be positioned on a smooth
concrete or asphalt pad providing adequate support. The pad should be clean, smooth
and level so it fully supports the entire tank bottom with no deflection. If a seismic
restraint system is used the pad must be adequate in size for anchor plate attachments
per the seismic code.
- Temperature:
- Product should not exceed 100 degrees F at delivery
or during storage to reduce decomposition of the Sodium Hypochlorite
Caution - The life of a tank is affected by the quality of the sodium hypochlorite
stored. Tank owners are cautioned to use high quality sodium hypochlorite with low
iron, nickel, and copper content. These metals contribute to the decomposition of
the sodium hypochlorite and accelerate the oxidation and degradation of the tank.
