Descriptions of NOBLEST Different Types of Tube Heat Exchangers
1. Shell and Tube Heat Exchanger / Fixed Tube and Sheet Heat Exchanger:
NOBLEST Shell and Tube Heat Exchanger The fixed tube-plate heat exchanger consists of a tube plate and a shell at both ends, making it widely utilized due to its simplistic structure. In this design, the tube plates at both ends of the bundle are welded to the shell. After welding with the shell, the tube plate can also function as a flange and is connected to the pipe box flange by bolts.
Applications: This equipment serves as an energy-saving solution for facilitating heat transfer between materials. It sees extensive application in industries such as petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food. With the ongoing expansion of energy-saving technology applications, utilizing heat exchangers for high and low-temperature heat recovery has yielded significant economic benefits.
Advantages: The simple structure ensures the shell's minimum inner diameter while maintaining the same heat transfer surface. A notable disadvantage is that significant temperature differences between the shell and pipe medium can lead to thermal stress, potentially causing pipe and tube plate failure, leakage, or instability. Additionally, maintenance and cleaning processes for the shell are inconvenient. Despite its widespread use, this design is limited by temperature differences.
2. U-shaped Style Tube Heat Exchanger
NOBLEST U-shaped Tube Heat Exchanger As a type of shell and tube heat exchanger, it belongs to petrochemical equipment. It is composed of main components such as the tube box, shell, and tube bundle. The U-shaped tube heat exchanger has only one tube plate, with both ends of the pipe fixed on the same plate.
Main Features: :
Δ The tube bundle can freely expand and contract without generating thermal stress due to temperature differences between the tube and shell,
Δ Excellent thermal compensation performance.
Δ The shell side features a double-tube flow with a longer flow path and higher flow velocity, resulting in enhanced heat transfer performance.
Δ High pressure resistance.
Δ The tube bundle can be withdrawn from the shell for easy maintenance and cleaning. The structure is simple and cost-effective.
Applications:
Ideal for situations with significant temperature differences between the tube and shell walls, or where the shell-side medium is prone to scaling while the tube-side medium is clean and less prone to scaling. Suitable for high temperature, high pressure, and strongly corrosive conditions.
3. Floating Head Tube Heat Exchanger
NOBLEST Floating Head Heat Exchanger In this model, only one end of the two ends of the tube plate is fixed to the shell, while the other end can move freely relative to the shell, known as the floating head. The floating head comprises a floating tube plate, hook ring, and floating head end cover. It is detachable, allowing the tube bundle to be drawn from the shell. This design eliminates thermal stress as the tube bundle and shell can thermally deform independently.
Features:
Advantages include convenient cleaning between tubes and no thermal stress generation. However, its structure is complex and the cost is higher than a fixed tube-plate heat exchanger. The equipment is bulky, with high material consumption, and the small cover of the floating head cannot be checked during operation, necessitating higher sealing requirements during manufacturing. It is suitable for scenarios with large wall temperature differences between the shell and the tube bundle or where the shell medium is prone to scaling.
Applications:
Δ The innovative tube bundle design allows for effortless extraction, ensuring convenient and thorough cleaning of both the tube and shell.
Δ Enjoy unparalleled flexibility with our heat exchanger, as it efficiently handles any temperature difference between mediums without limitations.
Δ Engineered for robustness, our heat exchanger operates seamlessly under high temperatures (up to 450 degrees) and pressures (up to 6.4 mpa), guaranteeing reliable performance.
Δ Ideal for environments with severe scaling, our heat exchanger maintains optimal functionality even in the harshest conditions.
Δ Designed to withstand corrosive environments, our heat exchanger ensures durability and longevity for your operations.
