Above-ground storage steel tanks are common in many industries. They store compressed gases and liquids. These tanks have diameters of over 5m and heights of above 10m. Those used to store compressed gases have double walls for additional safety.
The size and use of above-ground storage tanks call for expert manufacture. Experts will assemble all your tank’s parts on location, and then use different methods to put it up. Here are some of these methods.
1. Rolls Method
This is the ideal option if the shell and bottom of your tank consist of rolled sheets. Manufacturers make its roof from shields. Since the joining of already welded parts is mechanical, the rolls method is quick and requires minimal human labor.
The primary drawback of this method is that it only uses sheets with a maximum thickness of 14mm for low carbon steel and 18mm in low stainless steel.
2. Sheet-by-Sheet Method
In this method, manufacturers cut the roof, bottom, and shell of the tank, and then bend them according to precise dimensions. The tank is then erected from the bottom up.
It is a relatively inexpensive method since it requires no heavy lifting and complicated machines. The sheet-by-sheet method can also be used for tanks of varying shapes and sizes. It, however, takes a long time and many workers.
3. Lifting Method
This is a variation of the sheet-by-sheet method. A hydraulic jack lift is essential in installing the parts of your tank. It is safer and faster compared with the sheet-by-sheet method and is currently the typical method of above-ground tank manufacturing.
The critical factor that will influence the manufacturing method of your tank is its components. Regardless of the type, routine maintenance is essential to keep it in good working condition. Only experts handle these maintenance works to avert dangerous accidents.
