Does the vault tank specifically refer to the vertical fixed roof storage tank?

Fixed roof tanks include vault pipes, and there are other types.

A vault tank is a common type of storage tank that is typically used to store liquids or gases. It takes its name from its special tank roof structure, the vaulted tank roof. A vault tank can be a vertical fixed-top tank or other types of tanks such as floating top tanks or mobile top tanks.

Vertical fixed-top tanks are a common type of vault tank. It usually consists of a vertical cylindrical tank body and a fixed arched tank top. The tank roof usually consists of a series of steel plate arch members that are bolted together or welded together to form a solid arch structure.

The design of the vaulted tank roof ensures that no liquid or gas inside the tank leaks or is contaminated from the outside.

Vertical fixed-top tanks are typically used to store flammable, explosive, or toxic liquids or gases. They can be used in industries such as oil refining, chemical, pharmaceutical, food processing, etc. These tanks usually have a large capacity and can store thousands of tons of liquid or gas.

They can also be customized as needed to suit specific application needs.

In conclusion, a vault tank is a common type of storage tank, which can be a vertical fixed-top tank or other types of tanks. Vertical fixed-top tanks are typically used to store flammable, explosive, or toxic liquids or gases and have a large capacity and customization capabilities.

The fixed top tank is also called the vault tank, and the vault storage tank refers to a steel container with a spherical crown and a cylindrical tank with a tank top.

Therefore, even if the rotational molding of large and extra-large plastic parts, anti-corrosion storage tanks, etc., there is no need to use very cumbersome equipment and molds, and the processing and manufacturing of the machine mold is very convenient, the manufacturing cycle is short, and the cost is low.

Theoretically, there is almost no upper limit in size for parts molded by the rotational molding process. However, it is easy to make wisdom due to the limitations of production conditions and road transportation. The production of such large plastic containers, such as spit molding, does not require very expensive and bulky blow molding.

Equipment is impossible.

Suitable for molding large and extra-large parts:

The vast majority of plastic molding processing technology, in the molding process, plastic and mold Hu Yu are under a fairly high pressure (pressure), such as injection molding, compression molding, extrusion and other widely used injection molding, compression molding, extrusion and so on, so the application of these molding processes to produce large plastic parts, not only must use the Lingda mold that can withstand a lot of pressure, so that the mold becomes bulky and complex.

Moreover, the plastic molding equipment must also be designed and manufactured very firmly, and the processing and manufacturing difficulty of the machine mold increases accordingly, and the cost increases. In contrast, the rotational molding process only requires the frame to be strong enough to support the weight of the material, the mold and the frame itself, as well as the closing force to prevent material leakage.

A fixed-top storage tank is a common equipment for storing liquids or gases, which is usually used in industrial production, petrochemical industry, chemical engineering and other fields. It is characterized by a fixed top, non-movable, usually made of materials such as steel or concrete, and has high corrosion and pressure resistance.

The main structure of the fixed top storage tank includes the tank body, top cover, inlet and outlet pipelines, valves, instruments and other components. The tank is usually cylindrical or rectangular in shape, and the inside is coated with an anti-corrosion macro layer to protect the tank from corrosion. The top cover is usually round or square, fixed to the top of the tank, and can be used for the entry and exit of liquids or gases through the inlet and outlet pipes.

Fixed top storage tanks are used in a wide range of applications and can be used to store various liquids and gases, such as oil, gas, chemicals, food, beverages, etc. It has the advantage of large storage capacity and small footprint, which can effectively protect the quality and safety of stored substances.

However, there are also some disadvantages of fixed top storage tanks, such as the top cannot be opened, which is difficult to clean and maintain; The top is fixed, which cannot adapt to different storage needs; It is susceptible to the impact of natural disasters and man-made damage, and there are certain safety hazards.

In a word, the fixed top book storage tank is a common storage equipment, which has a wide range of application prospects and important economic value. During use, it is necessary to pay attention to safety and maintenance to ensure the quality and safety of stored substances.

That is, the design pressure is atmospheric pressure, that is, it is basically the same as the atmospheric pressure, the fixed top tank, the inner floating roof, the outer floating roof all belong to this, generally speaking, the fixed top tank is also called the vault tank, and the inner floating top tank is known as adding a layer of inner floating plate on the basis of the bright wax rolling of the vault tank to float on the oil surface. The outer floating roof tank is generally used for storage **, that is, the top of the tank floats up and down with the remaining oil surface.

Normally, the diameter and height are designed at 1:1, but if the site is limited, taking into account the nature of the material, there is a problem with fire spacing, and the diameter and height should be redesigned to comply with the regulations Man, asking this question is a bit general, so I am also general: In terms of infrastructure, the tank farm includes: .

Calculation of the insulation quantity of the vault oil tank: v 2 r (h formula, the r radius (not the cylindrical radius, the vault radius) is calculated by radians; h Vault protrusion height.

Horizontal storage tanks can be placed on the cart to transport circulating liquids Fixed storage tanks are mainly used for storing liquids.

There is not much difference. That is, in terms of maintenance, the horizontal tank is relatively convenient in maintenance. The footprint of the vertical tank is small.

Difference: The fixed top tank is also called the vault tank, and the vault storage tank refers to a steel container with a spherical crown and a cylindrical tank body. The vault storage tank is simple to manufacture and low cost, so it is most widely used in many industries at home and abroad, and the most commonly used volume is 1000-10000m3, and the maximum volume of the domestic vault storage tank has reached 30000m3.

Horizontal storage tanks are generally less than 100m3 in volume and are often used in production or at petrol stations. The circumferential weld of the horizontal storage tank adopts lap joint, and the longitudinal weld adopts butt. The ring plates are arranged interactively, and the singular number is taken so that the diameter of the end cap is the same.

The end cover of the horizontal storage tank is divided into a flat end cap and a dish-shaped end cap, the horizontal storage tank with the flat end cap can withstand 40kpa internal pressure, and the horizontal storage tank with the dish-shaped end cap can withstand the internal pressure. Underground horizontal storage tanks must be provided with reinforcing rings, which are also made of angle steel simmering.

Floating roof storage tanks are divided into floating roof storage tanks and internal floating roof storage tanks. The floating roof of the floating roof storage tank is a floating roof that floats on the surface of the liquid storage, which floats up and down with the input and output of the liquid storage, and there is an annular space between the floating roof and the tank wall. The inner floating roof storage tank is a floating roof tank with a tank roof, and it is also a new type of storage tank combining a vault tank and a floating roof tank.

The top of the inner floating roof tank is a combination of vault and floating roof, with a vault on the outside and a floating roof on the inside.

The floating roof of the floating roof storage tank is a floating top cover that floats on the surface of the liquid storage, which floats up and down with the input and output of the liquid storage, and there is an annular space between the floating roof and the tank wall, and this annular space has a sealing device, so that the liquid in the tank is isolated from the atmosphere when the top cover floats up and down, so as to greatly reduce the evaporation loss of the liquid storage during storage. When the floating roof tank is used to store oil, the oil loss can be reduced by about 80% compared with the fixed roof tank.

The tank with a floating roof in the open storage tank is called an outer floating roof tank or simply a floating roof tank. The inner floating roof tank is often used to store highly volatile media (such as gasoline, etc.) and media with harsh storage conditions. Outer floating top tanks are commonly used for storage**.

The floating roof can be moved up and down in the tank according to the level of the medium. Vault tanks have a relatively simple structure and are commonly used to store raw oils, refined oils and aromatic products.

Fixed top storage tank - the top structure is connected with the tank body by welding, the top is fixed, and it is divided into a vault and a cone top.

Floating roof storage tank - the top structure rises and falls with the rise and fall of the storage level in the tank, and the top is active, and it is divided into the inner floating roof and the outer floating roof.

The inner floating roof is not visible from the outside, and the outer floating roof is just the opposite.

The fixed tank is welded to the top of the tank and the wall of the tank. The inner floating roof is to add a sealed flat top in the tank on the basis of the fixed tank, and when generally working, the flat roof is in contact with the liquid in the tank, and the outer floating roof refers to the top of the tank moving up and down with the height of the liquid, and there is no welding with the tank wall.

Fixed top: The volatilization of oil is greater, but it can resist wind, snow, sand, etc.

Outer floating plate: the oil volatilization is small, but it cannot resist wind and snow, etc., and the quality of the oil is damaged.

Inner floating roof: It has the advantages of both of them, but the cost is high and the maintenance is inconvenient.

There is a difference in the storage medium, the small storage ** is the vault tank, the large capacity is the outer floating roof tank, and the storage of refined oil is the inner floating roof oil tank.

The inner floating roof tank is a combination of the vault and the floating roof, the outside is the vault, the inside is the floating roof, the internal floating roof can reduce fuel consumption, and the external floating roof can avoid rain, dust and other foreign objects into the tank, this tank is mainly used to store light oil products such as aviation kerosene.

The tank top of the oil tank of the outer floating roof is directly placed on the oil surface, and floats up and down with the entry and exit of the oil product, and there is a sealing device that moves up and down with the floating roof between the annular gap between the floating roof and the inner wall of the tank. The tank virtually eliminates gas space, so oil evaporation losses are greatly reduced.

The vault storage tank refers to a steel container with a spherical crown and a cylindrical tank body.

The vault storage tank is simple to manufacture and low cost, so it is most widely used in many industries at home and abroad, and the most commonly used volume is 1000-10000m3, at present, the maximum volume of the domestic vault storage tank has reached 30000m3.
