Explore the Superior NOBLEST Tube Heat Exchanger Range
1. Shell and Tube Heat Exchanger / Fixed Tube and Sheet Heat Exchanger:
NOBLEST Shell and Tube Heat Exchanger Excellence The fixed tube-plate heat exchanger by NOBLEST boasts a simple yet highly effective structure, featuring a tube plate and shell at both ends. This design is exceptionally popular due to its straightforward construction. In this model, the tube plates are welded to the shell at both ends of the bundle. The tube plate, after being welded to the shell, can function as a flange and be connected to the flange of the pipe box using bolts.
Applications: This heat exchanger excels as an energy-saving solution for efficient heat transfer between materials. It finds extensive applications across various industries, including petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food processing. With the widespread adoption of energy-saving technologies, the heat exchanger's role in both high and low-temperature heat recovery has substantially boosted economic benefits.
Advantages: The primary advantage of the fixed tube and sheet heat exchanger lies in its simplistic structure, which ensures the minimum inner diameter of the shell while maintaining consistent heat transfer efficiency. However, a significant drawback is the potential for thermal stress when there is a notable temperature difference between the shell and pipe medium, which may lead to pipe and tube plate failure, leakage, or instability. Additionally, the shell's maintenance and cleaning can be challenging. This design is widely used in general applications but is constrained by temperature differences.
2. U-shaped Style Tube Heat Exchanger
NOBLEST U-shaped Tube Heater The NOBLEST U-shaped tube heat exchanger, a part of petrochemical equipment, comprises key components such as the tube box, shell, and tube bundle. Unique to this design is the presence of only one tube plate, with both ends of the pipe secured on the same tube plate.
Main Features: Δ
Δ The tube bundle can expand and contract freely without thermal stress due to the temperature difference between the tube and shell.
Δ Excellent thermal compensation performance.
Δ The shell side features a double-tube flow, which has a longer flow path and higher velocity, enhancing heat transfer performance.
Δ High pressure resistance.
Δ The tube bundle can be easily removed from the shell for maintenance and cleaning, offering a simple and cost-effective structure.
Applications:
Ideal for scenarios with a significant temperature difference between the tube and shell walls or when 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 corrosive conditions.
3. Floating Head Tube Heat Exchanger
NOBLEST Floating Head Heat Exchanger The floating head heat exchanger by NOBLEST features a unique design where only one end of the tube plate is fixed to the shell, allowing the other end to move freely relative to the shell, thus forming the floating head. This floating head comprises a floating tube plate, hook ring, and floating head end cover. It is detachable, enabling the tube bundle to be removed from the shell, thus preventing thermal stress issues.
Features:
The floating head design offers the advantage of easy cleaning between tubes and prevents thermal stress. However, its complex structure and higher cost compared to fixed tubeplate heat exchangers, along with the larger equipment size and higher material consumption, are notable. Additionally, the small cover of the floating head cannot be inspected during operation, and the manufacturing process demands high sealing standards. It is best suited for applications where there is a significant wall temperature difference between the shell and tube bundle or where the shell medium tends to scale.
Applications:
Δ The tube bundle can be effortlessly drawn out, simplifying the cleaning process for both the tube and shell components.
Δ There are no limitations on the temperature difference between the mediums, offering versatile application possibilities.
Δ Designed to excel under extreme conditions, it operates efficiently at high temperatures up to 450 degrees and pressures up to 6.4 mpa.
Δ Ideally suited for applications involving severe scaling, ensuring reliable and consistent performance.
Δ Perfect for environments prone to pipe corrosion, offering durability and longevity.
