Pressure vessels play an important role in various industries. These tanks are used as a tool to store gases, liquids and solids under pressure and are used in oil and gas, petrochemical, pharmaceutical and many other industries. In this article, we will introduce the types of pressure vessels and their applications.
Pressure vessels are structures designed to store liquids or gases that require high pressure. These tanks usually have pressure-resistant walls that are made of different materials such as steel, stainless steel, aluminum, etc. In the design of pressure tanks, factors such as required pressure, storage volume, physical and chemical characteristics of the stored liquid, environmental conditions and the need for safety equipment are considered.
Types of pressure vessels
There are different types of pressure vessels, each of which is suitable for its own applications. In the following, some types of pressure tanks are mentioned:
Cylindrical tanks
Cylindrical tanks are one of the types of tanks with a cylindrical shape and are one of the most common types of pressure tanks. The cylindrical design mechanically guarantees the strength of the tank. These tanks are used as liquid storage and transportation tanks.
Spherical tanks
Spherical tanks have a spherical or semi-spherical shape and because of their circular shape, they work well in pressure distribution. These tanks are usually used to store pressurized gases.
Internal pressure vessels
These tanks are used to store liquids or gases inside buildings and industrial equipment. The internal design and structure of these tanks is designed to perform optimally under the internal pressure of the tank.
External pressure tanks
These types of tanks are designed for liquids that are pressurized from the outside. Examples of these types of tanks can be water or air pressure tanks for irrigation sources and air compressors.
Thermal pressure tanks
These tanks are designed to store liquids that require a certain temperature. They usually have heating systems to maintain the temperature.
Non-thermal pressure vessels
These types of tanks are designed to store liquids with high pressure but without the need for temperature control. These tanks are usually used in petrochemical and gas industries.
Thin-walled tanks
These tanks have thin walls and are mainly used to store expensive liquids such as crude oil.
Thick-walled tanks
These types of tanks have thicker walls and are suitable for explosive liquids. Choosing the right type of pressure tank depends on the desired application, the amount of pressure, the type of liquid or gas, and the operating conditions. Also, in the selection and installation of pressure tanks, attention should be paid to industrial standards and regulations to ensure the safety and efficiency of the tanks
Applications of pressure vessels
Oil and gas industry: In oil and gas mines, pressure tanks are used to store crude oil and natural gas.
Petrochemical industry: Pressure tanks are used in petrochemical projects to store materials such as ethylene, propylene and ammonia.
Power plants: These tanks are used in power plants to store steam and clean water.
Food industry: Pressure tanks are used in food industries such as dairy and bean production.
Pharmaceutical industries: These tanks are used to store the raw materials of drugs and chemicals in the pharmaceutical industry.
Important points in buying pressure tanks
Choosing the right type and material: The type and material of the tanks should be selected according to the liquid or substance in which it is stored. Some liquids may react with certain materials, so choosing the right material is critical.
Measurement and capacity: Carefully measure the amount of liquid or material to be stored in the tank and choose a tank with a suitable capacity.
Environmental conditions: The environment around the tank is also very important. If the tank is located in a dry and sunny environment, it needs special painting and insulation.
Safety equipment: Pressure vessels must be equipped with safety equipment such as fire extinguishing and pressure control systems.
Standards and regulations: Compliance with standards and regulations related to pressure vessels such as ASME (American Society of Mechanical Engineers) standard is very important.
Maintenance
Periodic planning of maintenance and repairs of pressure vessels is necessary to ensure their correct operation.
People who have expertise in the field of maintenance and repairs of pressure vessels, should take responsibility for this task and carry out repairs regularly.
To increase the useful life of tanks, original spare parts and suitable materials should be used.
Important points in delivery and installation
Before delivery of the tank, it should be carefully checked and necessary tests should be done to ensure its health and quality.
Installation of pressure vessels should be done by skilled technicians and professionals to ensure their correct and safe installation.
Before starting the tank, all parameters and safety equipment should be controlled.
Conclusion
Pressure tanks are very vital tools in various industries and their correct selection, installation, maintenance and repairs are of particular importance. Adhering to standards and regulations, choosing the right material and committing to periodic maintenance and repairs can help to increase the useful life and improve the efficiency of tanks. Also, paying attention to environmental and safety conditions in the delivery and installation of tanks is of particular importance.
