In this article, we will discuss what API STD 650 is, its scope, who should use it and how it can be obtained. Let’s find out together!
What is API STD 650?
API STD 650 is a standard set by the American Petroleum Institute (API) and is considered a general design standard for storage tanks. This standard has been developed to ensure the safe and proper construction of storage tanks made of various materials.
STD 650 Contains detailed guidelines setting out the design criteria for storage tanks. Important factors such as dimensions of storage tanks, material quality, load carrying capacity are discussed in detail.
This standard also covers topics such as weldability requirements, test procedures and maintenance instructions. This helps industry professionals to manage storage tanks effectively.
One of its main objectives is to minimize environmental risks and raise safety standards. In this way, potential hazards that facility owners may encounter in their operational processes can be minimized.
What is the Scope of API STD 650?
This standard has been established to ensure the safe and effective storage of liquids. Its scope is quite broad and covers a variety of topics.
This standard covers the design, construction, installation and maintenance of steel storage tanks. It also covers many technical issues, from welding details to surface preparation. It also sets requirements for fire protection.
The standard also includes methods for calculating the basic loads of storage tanks. It is at the forefront to determine safety standards by addressing different external factors from earthquake effects to wind loads.
This breadth of coverage of API STD 650 is invaluable for industry professionals and engineers. Designed and constructed in accordance with the standard, the storage tanks are long-lasting and reliable.
Who is API STD 650 Suitable for?
Professionals such as engineers, project managers, industrial plant owners and operations teams who want to comply with the rules set by this standard can benefit from API STD 650. It is important that everyone who works with storage tanks is familiar with this standard because it improves occupational safety and minimizes environmental impact.
People who want to examine API STD 650 are advised to have experience in the relevant field first. It is very important to understand and correctly interpret the technical terms in the standard. It is also important to note that this standard is constantly updated, so it is important to keep abreast of changes in the industry.
Comparison of API STD 650 with Other Standards
1. Comparison with API STD 653:
API STD 653 is known as the Standardization Program for the Operation, Maintenance, Replacement and Repair of Storage Tanks and has a similar scope to API STD 650. However, API STD 653 contains more detailed guidelines on the operation and maintenance of storage tanks, while API STD 650 deals with the design and construction of tanks.
2. Comparison with AWWA D100:
AWWA D100 is known as the Standardization Program for Water Storage Tanks and focuses on the design and construction of water storage tanks. API STD 650 applies to petroleum or chemical storage tanks.
3. Comparison with ASME Section VIII:
ASME Section VIII is the Standardization Program for Pressure Equipment and deals with the design and construction of pressure vessels. API STD 650 deals with the design and construction of non-pressurized storage tanks.
4. Comparison with EN 14015:
EN 14015 is the European Standard for Storage Tanks and has a similar scope to API STD 650. However, EN 14015 has more stringent design standards and specifies requirements for storage tanks in Europe.
5. Comparison with NFPA 30:
NFPA 30 is a standard published by the National Fire Protection Association (NFPA) that includes Standards for Fire Protection. Like API STD 650, NFPA 30 deals with the design and construction of storage tanks but focuses more on fire prevention and protection.
Design Criteria for Storage Tanks
1. Capacity of the Tank: One of the most important criteria in the design of the storage tank is the amount of material the tank will store. The capacity of the tank should be determined according to the volume and characteristics of the material to be stored. It should also have sufficient capacity, taking into account possible future expansion or production increases.
2. Material Specifications: The materials to be used in the design of storage tanks should be suitable for the properties of the substance to be stored. Factors such as chemical resistance, corrosion resistance and impermeability should be considered.
3. Tank Location: The location of the tank is important for both safety and operational efficiency. Being outside the storage area or in the open can increase security risks. It also needs to be in a convenient place for transporting the material and emptying the tank.
4. Storage Temperature: Some substances may require a constant temperature during storage. Therefore, this factor should also be taken into account in the design of the tank. It is also important to include the necessary equipment for temperature control in the design of the tank.
5. Tank Shape According to the Stored Material: According to the characteristics of the material to be stored, the shape and dimensions of the tank should be determined. For some substances cylindrical tanks are preferable, while for other substances flat or conical bottom tanks may be more suitable.
6. Fire Risk: If there is a high risk of fire in the storage area, the tank should be designed accordingly. Fire prevention systems and fire resistant materials should be used.
7. Storage Period: Some substances are subject to a limited storage period. Therefore, the storage time needs to be taken into account in the design of the tank.
8. Compliance with Local Legislation: Compliance with local legislation is very important in the design of storage tanks. All standards required for the safety of the tanks and environmental protection must be complied with.
9. Operational Needs: Operational requirements should also be considered in the design of the tank. The ease of access, replenishment and discharge of the substance to be stored is an important factor in the design of the tank.
10. Ease of Maintenance and Repair: The design of the tank should also take into account the ease and safety of maintenance and repair. The design of the necessary equipment and access routes is therefore important.
