API 650
API 650 refers to the American Petroleum Institute's (API) standard for welded steel tanks for oil storage. It provides minimum requirements for the design, material, construction, and testing of aboveground, vertical, cylindrical, closed- and open-top, welded steel storage tanks. These tanks are used primarily in the oil and gas industry for the storage of crude oil, refined products, and other liquids.
API 650 is widely recognized and adopted internationally as a standard for the construction of large, atmospheric-pressure, aboveground storage tanks. It is periodically updated by the API to incorporate new technologies and practices in tank design and construction
API 620
API 620 is another important standard published by the American Petroleum Institute (API), which deals with the design and construction of large, welded, low-pressure storage tanks. Unlike API 650, which covers tanks primarily designed for atmospheric pressure, API 620 is specifically for tanks that operate at internal pressures approximating atmospheric pressure or less.
API 620 is commonly used for tanks that store products such as liquefied natural gas (LNG), certain chemicals, and other liquids where low internal pressures are a design consideration. It ensures that these tanks are designed and constructed to safely withstand internal pressures while also addressing factors such as seismic design criteria and other operational considerations.

What is Cone roof storage tanks ?
Cone roof storage tanks are a type of aboveground storage tank typically used for storing liquids such as crude oil, gasoline, diesel, and chemicals. These tanks are characterized by their conical-shaped roofs, which are either permanently attached to the tank shell or constructed as a separate dome that is mounted on top. Here are some key features and
Construction: The cone roof is usually constructed from steel and is supported by rafters , columns and truss support on the tank shell. This design helps to provide structural integrity and support against environmental loads such as wind and snow.
Cone roof tanks are primarily used to store volatile liquids or those that can degrade if exposed to the atmosphere. The conical shape of the roof allows rainwater and snow to easily drain off, preventing accumulation that could otherwise cause corrosion or contamination.
Safety: These tanks are designed to minimize the risk of vapor emissions and to maintain the integrity of the stored product. They are often equipped with vapor recovery systems and pressure relief devices to ensure safe operation.
Applications: Common applications include storing petroleum products, chemicals, and other liquids in industries such as oil and gas, chemical manufacturing, and transportation terminals.
Advantages: Cone roof tanks offer advantages such as ease of maintenance, protection against atmospheric exposure, and relatively lower construction costs compared to other tank designs like floating roof tanks.
Overall, cone roof storage tanks are chosen based on the specific requirements of the stored liquid and the environmental conditions of the site where they will be located.
What is cone roof storage tanks design ?
The design of cone roof storage tanks is characterized by several key features that ensure structural integrity, functionality, and safety. Here are the main aspects of their design:
Tank Shell: The tank shell forms the cylindrical body of the storage tank and is typically constructed from welded steel plates. The thickness and grade of the steel plates depend on factors such as the size of the tank, the type of stored liquid, and environmental conditions. The shell is designed to withstand internal pressure from the stored liquid and external forces like wind and seismic loads.
Cone Roof: The cone roof is the distinctive feature of these tanks. It can either be an integral part of the tank shell or a separate structure mounted on top. The roof is typically made from welded steel plates and is sloped to facilitate drainage of rainwater and snow. The slope directs water towards a central drain or scupper, preventing accumulation that could lead to corrosion or weight issues.
Roof Supports: Cone roof tanks are supported by internal columns and rafters that connect the roof structure to the tank shell. These supports provide stability and distribute the load of the roof evenly to the tank walls. The number and design of supports depend on the tank size and the roof configuration
.
Accessories and Fittings: Cone roof tanks are equipped with various fittings and accessories depending on their specific application. These may include inlet and outlet nozzles for product transfer, overflow pipes, level gauges, temperature sensors, pressure relief devices, and venting systems to control vapor emissions.
Coatings and Linings: To protect against corrosion and maintain the quality of the stored liquid, the interior surfaces of cone roof tanks are often coated or lined with materials compatible with the stored product. Common lining materials include epoxy, polyurethane, or special coatings designed for specific chemicals or corrosive substances.
Design Standards: Cone roof storage tanks are designed and constructed following industry standards and codes to ensure safety, durability, and compliance with environmental regulations. Standards such as API (American Petroleum Institute) 650 provide guidelines for the design, fabrication, erection, and inspection of welded steel tanks, including cone roof tanks.
Ventilation and Emissions Control: Proper ventilation and emissions control systems are essential for cone roof tanks, especially when storing volatile liquids. Vent pipes and pressure relief valves are designed to safely manage vapor pressures and prevent over-pressurization of the tank.
Overall, the design of cone roof storage tanks aims to provide a robust and reliable structure for the safe storage of liquids while minimizing environmental impact and ensuring compliance with regulatory requirements. The specific design details may vary depending on factors such as tank size, location, stored product characteristics, and operational considerations.
What is advantages of cone roof tanks over floating roof tanks ?
Cone roof storage tanks offer several advantages over floating roof tanks, depending on the specific requirements of the stored liquid and the operational conditions. Here are some key advantages of cone roof storage tanks compared to floating roof tanks:
Lower Initial Cost: Cone roof tanks generally have a lower initial construction cost compared to floating roof tanks. This is because they do not require a complex floating roof mechanism, which includes pontoons, seals, and mechanisms for floating roof movement.
Simplicity of Design: The design of cone roof tanks is simpler compared to floating roof tanks. They consist of a cylindrical shell and a conical roof, which are relatively easier to fabricate, erect, and maintain.
No Maintenance of Floating Roof: Floating roof tanks require regular maintenance of the floating roof seals, pontoons, and other moving parts to ensure proper functioning and to prevent leakage. Cone roof tanks, on the other hand, have a stationary roof structure that generally requires less maintenance over their lifetime.
Suitability for Heavy Products: Cone roof tanks are often preferred for storing heavy products that do not easily evaporate and do not require the vapor control advantages offered by floating roof tanks. Heavy crude oils, for example, can be stored effectively in cone roof tanks without the need for a floating roof to minimize vapor space.
No Risk of Roof Sinking: In floating roof tanks, there is a potential risk of the roof sinking or tilting due to factors such as uneven distribution of stored product or external environmental conditions. Cone roof tanks do not face this risk since their roof structure is fixed and supported directly by columns and rafters.
Less Sensitive to Product Level: Floating roof tanks require careful consideration of the product level to ensure the floating roof remains properly floated and to avoid mechanical issues. Cone roof tanks do not have this sensitivity, as the roof structure remains stationary regardless of the product level.
Easier to Inspect: Inspecting the interior of cone roof tanks is generally easier compared to floating roof tanks. There are no internal floating roof components obstructing the view or requiring access for inspection and maintenance.
While cone roof tanks offer these advantages, it's important to note that the choice between cone roof and floating roof tanks depends on factors such as the volatility of the stored product, environmental regulations, operational requirements, and overall lifecycle costs. Each tank type has its own set of applications and considerations based on the specific needs of the storage facility and the characteristics of the stored liquids.
