Explore the Range of NOBLEST Tube Heat Exchangers with Advanced Design and Efficiency
1. Shell and Tube Heat Exchanger / Fixed Tube and Sheet Heat Exchanger:
NOBLEST Shell and Tube Heat Exchanger This robust fixed tube-plate heat exchanger features a tube plate and a shell at both ends, making it remarkably efficient due to its straightforward structure. The design ensures the tube plates at both ends are securely welded to the shell. Post-welding, the tube plate serves as a flange, connecting seamlessly to the pipe box flange with bolts.
Applications: An exemplary energy-saving apparatus, this exchanger optimizes heat transfer between materials, making it indispensable across petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food industries. The progressive application of energy-saving technologies has significantly enhanced the economic benefits of high and low-temperature heat recovery.
Advantages and Limitations This design excels with its minimalistic structure, ensuring the smallest inner diameter of the shell while maintaining optimal heat transfer surface area. However, considerable temperature differences between the shell and pipe medium may induce thermal stress, potentially leading to pipe and tube plate failure, leakage, or instability. Maintenance and cleaning of the shell can be cumbersome. Despite its widespread use, temperature differences limit its application.
2. U-shaped Tube Heat Exchanger
NOBLEST U-shaped Type Tube Heater This petrochemical equipment consists of main components like the tube box, shell, and tube bundle. The U-shaped heat exchanger is unique with only one tube plate, fixing both ends of the tube on the same plate.
Key Features: :
Δ The tube bundle can freely expand and contract without causing thermal stress due to temperature variations between the tube and shell,
Δ Excellent thermal compensation performance,
Δ Enhanced heat transfer performance due to longer flow path and higher flow velocity on the shell side with double-tube flow,
Δ High pressure resistance,
Δ Simplified maintenance and cleaning due to the withdrawable tube bundle, offering a cost-effective solution.
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. It excels under high temperature, high pressure, and highly corrosive conditions.
3. Floating Head Tube Heat Exchanger
NOBLEST Floating Head Heat Exchanger With only one end of the tube plate fixed, the other end is free-moving relative to the shell, forming the floating head. This assembly includes a floating tube plate, hook ring, and floating head end cover, all detachable, allowing for the tube bundle to be drawn out from the shell, eliminating thermal stress issues.
Features:
This design offers easy cleaning between tubes and eradicates thermal stress. However, its complex structure, higher cost compared to fixed tube-plate exchangers, bulky form, and higher material consumption are notable. The small floating head cover is not inspectable during operation and demands high sealing standards during manufacturing. It is advantageous for applications with significant temperature differences between the shell and tube bundle walls or where the shell medium may scale.
Applications:
Δ The tube bundle can be easily extracted, ensuring effortless cleaning of both the tube and shell, streamlining your maintenance process.
Δ There are no limitations on the temperature difference between the media, giving you versatile control over a wide range of applications.
Δ Designed to excel under extreme conditions, it operates efficiently at temperatures up to 450 degrees Celsius and pressures up to 6.4 MPa.
Δ Ideal for environments prone to severe scaling, ensuring reliable and consistent performance.
Δ Perfect for applications where pipe corrosion is a concern, offering robust protection and durability.
