What is an Expansion Tank?
Expansion Tanks, also known as expansion tanks, are plumbing equipment that provide pressure control and water support in plumbing systems.
In systems that prepare hot domestic water in residential and commercial buildings, the average water temperature is 80°C. The temperature of the supply water is considered to be 10°C. In this case, the value of the water passing through the system changes constantly between 10°C and 80°C. The specific volume of water also changes depending on this temperature. Expansion tanks are used to correct the expanding water volume as it heats up, thereby protecting the system.
There are two types of expansion tanks: open and closed.
Open Expansion Tanks
Open expansion tanks operate in an open atmosphere. They protect the system by preventing the plumbing from exceeding this pressure based on atmospheric pressure.
Closed Expansion Tanks
Closed expansion tanks, which work with a manometer and safety valve in systems where an open expansion tank cannot be installed and operate at larger capacities, are preferred.
Considerations When Choosing an Expansion Tank
When choosing an expansion tank, the following features should be considered:
- Capacity (in liters)
- The height of the location to be used
- Pressure resistance
- Auxiliary equipment to work with the expansion tank
How are Expansion Tank (Hydropneumatic Tank) Prices Calculated?
Expansion tank prices are calculated based on criteria such as capacity (in liters), the height of the location to be used, pressure resistance, and whether it is a horizontal or vertical expansion tank.
Expansion Tanks: Vital Role in Fluid Systems, Working Principle, and Application Areas
Expansion tanks are critical components that balance pressure fluctuations in fluid systems to ensure system stability.
Their functionality is essential to balance the volume changes of fluids according to temperature changes. These tanks are used in many industrial and domestic applications and have various structural and functional features.
**Working Principle and Structural Details**
The basic function of expansion tanks is to balance the expansion and contraction of the fluid due to temperature changes to control pressure fluctuations in the system. These tanks are generally located in a closed system and consist of two main components: an internal volume and an external shell. The internal volume is lined with a flexible material that allows the fluid to expand and contract. This material is usually a membrane or an elastic substance. By adapting to changes in the volume of the fluid, it absorbs pressure changes and balances them to ensure system stability. The external shell is a protective casing surrounding the expansion tank and is usually made of durable materials such as steel or plastic. This casing protects the interior of the tank from external influences and enhances the tank's robustness.
**Application Areas and Types**
Expansion tanks are used in many different application areas and can be found in various types. In heating systems, expansion tanks are typically located next to boilers or hot water storage tanks. These tanks control the expansion of heated water and maintain system stability by balancing the pressure in the system. In cooling systems, expansion tanks are also essential. Particularly in large industrial cooling systems, the expansion of the cooling fluid due to temperature changes is a significant issue. Expansion tanks absorb the expansion of the cooling fluid and balance pressure changes to ensure safe and efficient operation of the system. Expansion tanks play a vital role in hydraulic systems as well. The expansion of the fluid in hydraulic systems due to temperature changes can cause pressure fluctuations in the system, which can negatively affect system performance. Expansion tanks balance these pressure changes to improve system performance and ensure the components last longer.
Expansion tanks come in different types according to application requirements. Pressure vessels, membrane tanks, surface tanks, and many other types of expansion tanks are available. This variety offers solutions suitable for different industrial and domestic applications, making systems safer, more efficient, and more durable.
In summary;
Expansion tanks are critical components that balance pressure fluctuations in fluid systems to ensure system stability. They are widely used in heating, cooling, hydraulic, and many industrial applications. With their structural diversity and application flexibility, expansion tanks offer solutions tailored to different requirements, making systems safer, more efficient, and more durable. Therefore, expansion tanks play an important role in fluid systems and find a place in a wide range of applications, from modern industrial facilities to residential use.
