Vulcan Tank

Vulcan galvanized tanks provide excellent corrosion protection and design flexibility to fit on any site.

Vulcan Versatank

Vulcan tanks are used for the storage of water for the fire sprinkler, potable water and irrigation.

 

Galvanized tanks are an economical way of storing liquids. Galvanized steel bolted tanks can be manufactured as round tanks in either bolted or welded designs or a rectangular VersaTank tank with or without a liner. These tanks are primarily used for the storage of water for the fire sprinkler, potable water and irrigation markets.

Specially Designed Lap Joint

The tanks are site assembled using overlapped and bolted galvanized flat steel panels that are specially manufactured at CST. The tank is sealed with a choice of mastic or by using synthetic rubber membrane. A choice of covers can be selected giving a reliable and low maintenance solution for water storage.

Using a trough deck roof generally matches the economic strategy of galvanized tanks. The unique nature of the galvanizing process provides a tough and abrasion resistant coating that is self-healing and long lasting and has many benefits of steel corrosion protection systems.

Protection by Sacrificial Action

Zinc used in the galvanizing process corrodes in preference to steel and sacrifices itself to protect the steel. The corrosion products from the zinc are deposited on the steel resealing it from the atmosphere and therefore preventing corrosion.

Cylindrical Vulcan Galvanized Tanks

Cylindrical Galvanized tanks are constructed from sheets that are manufactured from mill galvanized steel in accordance with the customer's specifications including ASTM, ASME or BS EN 10204 or from steel in accordance with ASME, ASTM or BS EN 10025 that is subsequently hot dipped galvanized to ASTM, ASME or BS EN 1461:1999 standards.

The sheets are assembled to one another on site using galvanized bolts. The tank shell is fixed to a concrete foundation. Sealing of the tank is accomplished by either using a high pressure curing mastic around the joints and bolt holes, or by fitting the tank with an internal synthetic rubber membrane liner.

The tank can be supplied with a roof, galvanized access ladder and platform, and inlet and outlet connections. Insulated walls and roof are also available where risk of a consistently low temperature would cause ice damming and other potentially destructive conditions. Other ancillary items can also be provided.

Rubber Liners

Cylindrical galvanized tanks can be sealed using liners manufactured from either EPDM or BUTYL synthetic rubber membranes. EPDM and BUTYL membrane sheeting provides a completely waterproof seal due to its closely packed molecular structure making it extremely resistant to the transmission of liquids and vapors.

EPDM and BUTYL both have outstanding aging and weather-resistant properties. Their cross-linked molecular structure gives excellent aging over a long period of time even when exposed to the atmosphere, sunlight, ultraviolet radiation and ozone. Strength and elasticity remains virtually unchanged over many years, without shrinking, hardening or cracking. Liners manufactured from BUTYL rubber have received approval from the UK Water Regulators Advisory Scheme (WRAS) in accordance with BS6920, for use in the storage of potable water.

VERSATANK

Versatile Rectangular Design

VersaTank offers versatility of design enabling sprinkler water storage tanks to be designed and installed where traditional cylindrical designs cannot easily be accommodated. The corrugated galvanized sheets that are used to construct the tank provide flexibility in design and ensure that the most demanding space restrictions can be accommodated.

Almost any shape can be designed with obstructions such as building support columns easily encapsulated within the tank. Whether the location is in a cramped basement or in an external restricted site, VersaTank can provide the solution.

The tank shell is fixed to the concrete foundation using galvanized angles, clamps and bolts with similar stiffening angles fixed to the top of the tank shell and knee bracing internal supports on every vertical seam.

The sheets are assembled to one another on site using a lap joint and galvanized silo bolts. The tank shell is fixed to a concrete foundation. Sealing of the tank is accomplished by either using a high pressure curing mastic around the joints and bolt holes together with a 150mm seal pour of concrete.

The tank is supplied with a galvanized corrugated low profile roof cover that is plastic coated on the external side. A galvanized access ladder and platform, inlet and outlet connections, and other ancillaries such as ball valves, heater contents gauge can be included if required.

Applications

CST Vulcan galvanized tanks are ideal for the following applications:

Fire Protection

Vulcan galvanized tanks are ideally suited for fire protection water storage. Vulcan is a recognized brand name in fire suppression storage systems.

Industrial Water

Galvanized tanks provide an economical solution to any industrial water application.

Potable Water and Wastewater

In some countries, galvanized tanks are accepted for use with potable water and wastewater applications. They are an economical option for any of these applications when approved.
