Detailed 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 This fixed tube-plate heat exchanger boasts a design comprised of a tube plate and a shell at both ends, making it a staple in various applications due to its straightforward structure. In this type, the tube plates at both ends are securely welded to the shell. The tube plate can function as a flange after welding with the shell, then it is bolted to the pipe box flange for a robust connection.
Applications: An epitome of energy-saving technology, this heat exchanger excels in facilitating heat transfer across a multitude of materials. It is highly sought after in petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food industries. As energy-saving technologies evolve, the deployment of heat exchangers in both high and low temperature heat recovery continues to generate considerable economic benefits.
Advantages and Disadvantages: The primary advantage lies in its simplistic design, which ensures the smallest possible inner diameter of the shell while maintaining a consistent heat transfer surface area. However, a significant drawback is the thermal stress induced by notable temperature differences between the shell and pipe medium, potentially causing pipe and tube plate failures, leaks, or instability. Additionally, maintenance and cleaning can be cumbersome. Despite these limitations, it remains prevalently used in general applications restricted by temperature variance.
2. U-shaped Style Tube Heat Exchanger
Noblest U-shaped Tube Heat Exchanger This type of shell and tube heat exchanger, which falls under the realm of petrochemical equipment, features a design that includes a tube box, shell, and tube bundle. The U-shaped configuration includes only one tube plate, with both ends of the tube fixed on this single plate.
Main Features: :
Δ The tube bundle can expand and contract freely without causing thermal stress due to temperature differences between the tube and shell.
Δ It offers exceptional thermal compensation performance.
Δ The shell side utilizes double-tube flow with an extended flow path and higher velocity, resulting in superior heat transfer performance.
Δ It boasts high pressure resistance.
Δ The tube bundle is easily removable from the shell for maintenance and cleaning, offering a simple and cost-effective structure.
Applications:
Ideal for scenarios 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 remains clean and scale-resistant. Suitable for high temperature, high pressure, and highly corrosive environments.
3. Floating Head Tube Heat Exchanger
Noblest Floating Head Heat Exchanger In this design, only one end of the two tube plates is fixed to the shell, allowing the other end to move freely relative to the shell, forming what is known as the floating head. The floating head consists of a floating tube plate, a hook ring, and a floating head end cover. This design is detachable, enabling the tube bundle to be easily withdrawn from the shell, thus eliminating thermal stress.
Features:
The notable advantages include easy cleaning between tubes and absence of thermal stress. However, its complex structure and higher cost compared to fixed tube-plate heat exchangers, along with the bulkiness and significant material consumption, are drawbacks. The small cover of the floating head cannot be inspected during operation, and higher sealing standards are required during manufacturing. This heat exchanger is best suited for applications with large wall temperature differences between the shell and tube bundle or where the shell medium is prone to scaling.
Applications:
Δ Enjoy effortless maintenance as the tube bundle can be easily drawn out, ensuring seamless cleaning of both the tube and shell process;
Δ Experience unparalleled flexibility with no limitations on the temperature difference between mediums;
Δ Designed to endure extreme conditions, it operates efficiently under high temperatures up to 450 degrees and pressures up to 6.4 MPa;
Δ Perfectly suited for environments with severe scaling, ensuring reliable performance;
Δ Ideal for applications where pipe corrosion is a concern, providing robust resistance;
