Exquisite Descriptions of NOBLEST's Diverse Tube Heat Exchanger Types
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, renowned for its simplistic structure and extensive utility. This design features tube plates welded to the shell at both ends of the bundle, which can double as a flange once welded. This flange is then bolted to the pipe box flange, ensuring robust connectivity.
Applications: This heat exchanger is a pinnacle of energy-saving equipment, enhancing heat transfer between various materials. It is extensively utilized across industries such as petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food. With the evolution of energy-saving technologies, its role in high and low-temperature heat recovery is increasingly prominent, delivering substantial economic benefits.
Advantages The hallmark of this design is its simple structure, maintaining a minimal inner shell diameter while ensuring an ample heat transfer surface. However, a significant temperature disparity between the shell and pipe medium can introduce thermal stress, potentially causing pipe and tube plate failures, leaks, or instability. Furthermore, shell maintenance and cleaning are less convenient. Despite these challenges, it remains widely employed for general applications, albeit limited by temperature differentials.
2. U-Shaped Style Tube Heat Exchanger
NOBLEST U-Shaped Type Tube Heater This shell and tube heat exchanger, classified as petrochemical equipment, comprises key components such as the tube box, shell, and tube bundle. The U-shaped tube heat exchanger features a singular tube plate with both ends of the pipe affixed to this plate.
Main Features :
Δ The tube bundle can freely expand and contract, avoiding thermal stress due to temperature differences between the tube and shell,
Δ Excellent thermal compensation performance;
Δ The shell side utilizes a double-tube flow design, extending the flow path and increasing the flow velocity, thus enhancing heat transfer performance;
Δ High pressure resistance;
Δ The tube bundle can be extracted from the shell for maintenance and cleaning, offering a simple and cost-effective structure.
Applications:
Ideal for scenarios where there is a significant temperature difference between the tube and shell walls, or where the shell-side medium is prone to scaling while the tube-side medium remains 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 design, one end of the tube plate is fixed to the shell, while the other end moves freely relative to the shell, constituting the floating head. The floating head comprises a floating tube plate, a hook ring, and a floating head end cover. This detachable design allows the tube bundle to be drawn from the shell, preventing thermal stress by accommodating thermal deformation of both the tube bundle and the shell.
Features:
Its standout advantages include ease of cleaning between tubes and the absence of thermal stress. However, its complexity and higher cost compared to fixed tubeplate heat exchangers, along with bulkiness and significant material consumption, pose challenges. Additionally, the small cover of the floating head cannot be inspected during operation, necessitating higher sealing requirements during manufacturing. This design is best suited for situations with large wall temperature differences between the shell and tube bundle, or where the shell medium tends to scale.
Applications:
Δ The tube bundle can be effortlessly extracted, ensuring hassle-free cleaning of both the tube and shell sections;
Δ There are no restrictions on the temperature differential between the media, offering unparalleled versatility;
Δ Designed to function seamlessly under extreme conditions, it operates efficiently at temperatures up to 450 degrees Celsius and pressures reaching 6.4 MPa;
Δ Exceptionally suited for environments with severe scaling, ensuring reliable performance;
Δ Ideal for applications where the pipes are prone to easy corrosion, extending their longevity;
