In-depth Descriptions of NOBLEST's Varied 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 consists of tube plates and a shell at both ends, making it widely acclaimed for its straightforward design. It features tube and shell heat exchange, where tube plates at both ends are welded to the shell. Post welding, the tube plate doubles as a flange, connected by bolts to the pipe box flange.
Applications: This energy-efficient apparatus is pivotal for heat transfer between materials, extensively utilized across petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food sectors. As energy-saving technologies expand, the role of heat exchangers in high and low temperature heat recovery demonstrates significant economic advantages.
Advantages: The simple structure ensures a minimal inner shell diameter while maintaining optimal heat transfer surface. However, a notable drawback is the thermal stress caused by large temperature differences between the shell and pipe mediums, potentially leading to pipe and tube plate failure, leaks, or instability. Additionally, shell maintenance and cleaning can be challenging. Despite widespread general use, this design's efficacy is limited by temperature variances.
2. U-shaped Style Tube Heat Exchanger
NOBLEST U-shaped Tube Heater This shell and tube heat exchanger, a cornerstone of petrochemical equipment, comprises tube box, shell, and tube bundle. The U-shaped design features a single tube plate, securing both ends of the pipe.
Main Features: :
Δ The tube bundle can expand and contract freely without thermal stress due to temperature variances between the tube and shell,
Δ Excellent thermal compensation performance;
Δ Double-tube flow on the shell side, offering a longer flow path and higher flow velocity, thus enhancing heat transfer efficiency;
Δ High pressure resistance;
Δ The tube bundle is easily removable for maintenance and cleaning, featuring a simple, cost-effective structure.
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 remains clean and scale-free. Suitable for high temperature, high pressure, and highly corrosive conditions.
3. Floating Head Tube Heat Exchanger
NOBLEST Floating Head Heat Exchanger In this design, only one tube plate end is fixed to the shell while the other end moves freely, termed as the floating head. Comprising a floating tube plate, hook ring, and floating head end cover, it is detachable, allowing the tube bundle to be removed from the shell. This design prevents thermal stress by accommodating thermal deformation in the tube bundle and shell.
Features:
Its strengths include ease of cleaning between tubes and avoiding thermal stress. However, the complex structure, higher cost compared to fixed tubeplate heat exchangers, bulky equipment, and greater material consumption are notable drawbacks. Additionally, the floating head’s small cover cannot be inspected during operation, and higher sealing requirements are demanded during manufacturing. It 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 The ingenious design of the tube bundle allows for easy extraction, significantly simplifying the cleaning process for both the tube and shell.
Δ Our heat exchanger excels with an unrestricted temperature difference between the mediums, offering unparalleled flexibility.
Δ Built to withstand extreme conditions, it operates efficiently under high temperatures up to 450 degrees and pressures up to 6.4 MPa.
Δ Ideal for challenging environments where scaling is a significant concern, ensuring reliable performance.
Δ Perfectly suited for applications involving highly corrosive pipes, providing robust and durable solutions.
