Descriptions of NOBLEST different type Tube Heat Exchanger
1. Shell and Tube Heat Exchanger/ Fixed Tube and Sheet Heat Exchanger:
NOBLEST Shell and Tube Heat Exchanger The fixed tube-plate heat exchanger features a simplistic yet highly effective design, consisting of a tube plate and a shell at both ends. In this configuration, the tube plates at both ends of the bundle are welded to the shell, which can also serve as a flange after welding. This connection is secured with bolts to the flange of the pipe box. Its straightforward structure makes it widely utilized across various industries.
Applications: As an energy-efficient solution for facilitating heat transfer between materials, this heat exchanger finds extensive application in petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food sectors. The continuous expansion of energy-saving technologies has significantly enhanced the economic benefits of utilizing heat exchangers for both high and low temperature heat recovery.
The advantage of the fixed tube-plate heat exchanger lies in its uncomplicated structure, ensuring minimal inner diameter of the shell while maintaining efficient heat transfer surface. Despite its many benefits, a considerable temperature difference between the shell and pipe medium may lead to thermal stress, potentially resulting in pipe and tube plate failure, leakage, or instability. Additionally, maintenance and cleaning of the shell can be challenging. While this design is prevalent in general applications, it is constrained by temperature variations.
2. U-Shaped Style Tube Heat Exchanger
NOBLEST U-Shaped Type Tube Heat Exchanger is a specialized shell and tube heat exchanger tailored for petrochemical applications. Comprising key components such as a tube box, shell, and tube bundle, this heat exchanger is characterized by a singular tube plate, with both ends of the pipe fixed on the same tube plate.
The main features :
Δ The tube bundle can freely expand and contract, eliminating 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, offering a longer flow path and higher flow velocity, thus enhancing heat transfer performance;
Δ High pressure resistance;
Δ The tube bundle can be easily withdrawn from the shell for maintenance and cleaning, making the structure both simple and cost-effective.
Applications:
Ideal for scenarios with significant temperature differences between 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. It is also suitable for high temperature, high pressure, and highly corrosive conditions.
3. Floating Head Tube Heat Exchanger
NOBLEST Floating Head Heat Exchanger is ingeniously designed, with only one end of the tube plate fixed to the shell, while the other end remains free to move relative to the shell. This unique 'floating head' configuration includes a floating tube plate, hook ring, and floating head end cover, all of which are detachable, allowing the tube bundle to be withdrawn from the shell. This design ensures that thermal deformation of the tube bundle and shell are unconstrained, thereby eliminating thermal stress.
Features:
Offering easy cleaning between tubes, this heat exchanger eliminates thermal stress. However, its complex structure and higher cost compared to fixed tube-plate heat exchangers, as well as bulkiness and significant material consumption, may be considered drawbacks. Furthermore, the small cover of the floating head cannot be inspected during operation, and it demands higher sealing requirements during manufacturing. This design is best suited for applications with substantial temperature differences between the shell and tube bundle or where the shell medium is prone to scaling.
Applications:
Δ Easily maintain your system with our U-Shape Tubular Heat Exchanger, as the tube bundle can be effortlessly removed for thorough cleaning of both the tube and shell processes.
Δ Operate with unmatched flexibility, as our heat exchanger is designed to handle unlimited temperature differences between media without restrictions.
Δ Experience superior performance under extreme conditions, withstanding high temperatures up to 450 degrees Celsius and pressures up to 6.4 MPa, making it ideal for demanding industrial environments.
Δ Perfect for challenging applications, our heat exchanger is specifically designed to function efficiently even in environments prone to severe scaling.
Δ Optimal for corrosive conditions, our U-Shape Tubular Heat Exchanger is tailored for scenarios where pipe corrosion is a significant concern.
