The vault is the most widely used tank top style of vertical API 650 insulated tanks. The main shape of the vault is a sphere. It has a simple structure, excellent rigidity, and can withstand higher residual pressure. The dome of the dome cover is the first part of the ball. It is composed of a central roof and a fan-shaped top plate. When the tank diameter is relatively large, reinforcement ribs should be welded on the inner side of the top plate.
The central top plate is also called the central cover plate, and the fan-shaped top plate is generally made of an even number and arranged symmetrically. The outer side of the vertical API 650 insulated tanks roof shall be continuously welded. There are two forms of vault cover: one is the structure where the tank top and the tank wall are connected by arc transition welding. Its edge stress is small and the pressure bearing capacity is high, but it needs to be stamped and formed. The other is a structure in which the dome and the tank wall are separately welded and connected by edge-wrapped angle steel, which is more convenient to manufacture and is widely used in liquid storage tanks with lower pressure.
