The following short description gives the working procedure in outline. It can in certain details be modified when required.
Step 1. The tank bottom – plates are placed on the prepared foundation and welded together.
Step 2. The beams or lattice work of the roof are assembled and finally joined to the upper rim of the shell ring.
Step 3. The jacking equipment is installed in the tank. The plates of the second shell ring (next to the top ring) are positioned outside the first one.
Step 4. The completed part of the tank (roof and top shell ring) is lifted hydraulically to a height at which the plates of the second ring can be moved into place and the roof sheeting can be completed.
Step 5. The plates of the second shell ring are located exactly and welded together to the lower edge of the first ring.
Step 6. The plates of the third shell ring are placed outside the second shell ring.
Step 7. The completed part of the tank (roof the two uppermost shell rings) is lifted.
Step 8. The above cycle of operations is repeated until the last (bottom) shell ring is finished.
Step 9. The entire tank is lowered down to the bottom plate and welded to this.
Step 10. The lifting equipment is dismantled.
The tank construction process needs two kinds of equipment, respectively is the welding machine and the hydraulic jacking system, the welding machine is divided into the horizontal welding machine and the vertical welding machine;the hydraulic jacking system is also divided into senior hydraulic jacking system and simple hydraulic jacking system.(If your tank is bottom to top,you don’t need the hydraulic jacking system.)
In recent years, we have received a lot of customer demand, they want to have a special hydraulic roof for lifting granaries and enamel tanks.
Common tank bottom welding processes are as follows: Welding flat bottom process; Ball bottom welding process; Welding cone bottom process.
With the development of the economy, the storage tank capacity is getting larger and larger, and now tens of thousands of cubic meters of storage tanks are everywhere, and the bottom area of the tank is also increasing with the capacity. The bottom plate of the storage tank is composed of a pluralit
As a common storage facility, silos are widely used in agriculture, food processing and chemical industries. To ensure the safe, stable and efficient operation of silos, the design and implementation of its construction scheme is very important. This paper will introduce a typical silo construction
