1. Higher temperatures may be allowed, but the service life of the tank will be reduced, and a different resin may be required. See Derakane’s latest Chemical Resistance Guide.
2. For concentrations below 70% with temperatures below 150° F., isophthalic polyester resin may be used in the structural layers if spills are not a concern and to reduce cost.
CAUTION! Solutions above 50% may discolor the fiberglass tank. A fiberglass tank should NEVER be used to store concentrations above 80%.
Co/MEKP (Cobalt Octoate / Methyl Ethyl Ketone Peroxide)
Hot air post cure after assembly for four hours @ 180˚ F.
If the sulfuric acid tank is to be located outdoors:
- Each tank has U.V. inhibitor in the exterior resin layer.
- Gel coat may be added as an option.
Belding Tank uses only Integral (neck and flange face molded together) flanged nozzles.
Bolting Material: T-316 S.S. Standard (Hastelloy-C Optional)
Gasket Material: EPDM Standard (Viton Optional)
Unless otherwise noted, all tanks are designed for atmospheric pressure only.
Belding Tank recommends the vent be equal to or larger than the largest inlet or outlet fitting.
Plumbing to the tank:
Use of flexible connections resistant to sulfuric acid –
- Allows for lateral and vertical expansion and contraction of the sulfuric acid storage tank
- Reduces pump and piping vibration stress on the sulfuric acid tank
NOTE: Flexible Connections should be connected to the tank flange. Piping, valves and pumps must have structural support independent of the tank.
