Explore the Diverse Range of Tube Heat Exchangers by NOBLEST: Tailored for Optimal Performance in LNG and Various Industries
1. Shell and Tube Heat Exchanger / Fixed Tube and Sheet Heat Exchanger:
NOBLEST Shell and Tube Heat Exchanger: The Pinnacle of Efficient Design The fixed tube-plate heat exchanger features a tube plate and a shell at both ends, making it widely utilized due to its straightforward design. In this heat exchanger, the tube plates at both ends of the bundle are welded to the shell. Post-welding, the tube plate can also serve as a flange, which connects with the flange of the pipe box via bolts. This simplistic structure ensures reliability and ease of use.
Applications: This energy-saving equipment promotes heat transfer between materials, making it indispensable in industries such as petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food. With the expansion of energy-saving technologies, heat exchangers have significantly boosted economic benefits through high and low-temperature heat recovery.
The Advantage This exchanger boasts a simple structure, minimizing the shell's inner diameter while maintaining an effective heat transfer surface. However, a significant temperature difference between the shell and pipe medium can induce thermal stress, potentially causing pipe and tube plate failure, leakage, or instability. Maintenance and shell cleaning can be challenging, and although widely used, the design is somewhat constrained by temperature differences.
2. U-shaped Style Tube Heat Exchanger
NOBLEST U-shaped Tube Heater: Advanced Petrochemical Equipment This shell and tube heat exchanger is a sophisticated piece of petrochemical equipment, comprising essential components like a tube box, shell, and tube bundle. The U-shaped tube heat exchanger features a single tube plate, with both pipe ends fixed on the same plate, ensuring robust and efficient performance.
The Main Features :
Δ The tube bundle can freely expand and contract without generating 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 for superior heat transfer performance.
Δ High-pressure resistance.
Δ The tube bundle can be removed from the shell for maintenance and cleaning, ensuring a simple and cost-effective structure.
Applications:
Ideal for scenarios with significant temperature differences between tube and shell walls, prone to scaling on the shell-side medium while the tube-side medium remains clean, high-temperature, high-pressure, and highly corrosive conditions.
3. Floating Head Tube Heat Exchanger
NOBLEST Floating Head Heat Exchanger: Adaptable and Durable Design In this design, only one end of the tube plate is fixed to the shell, allowing the other end to move freely relative to the shell, creating a 'floating head.' The floating head assembly includes a floating tube plate, hook ring, and floating head end cover, making it detachable and allowing the tube bundle to be extracted from the shell. This design prevents thermal stress as the thermal deformation of the tube bundle and shell are independent.
Features:
Advantages include easy cleaning between tubes, along with the elimination of thermal stress. However, the complexity of its structure and higher cost compared to fixed tube-plate heat exchangers, along with bulky equipment and higher material consumption, are considerations. The small floating head cover cannot be inspected during operation, and manufacturing demands high sealing precision. It is suitable 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 innovative tube bundle design can be easily removed, streamlining the cleaning process for both the tube and the shell.
Δ Our heat exchanger operates efficiently without limitations on temperature differences between the mediums.
Δ Engineered to perform under high temperature and high pressure conditions, it can handle temperatures up to 450 degrees Celsius and pressures up to 6.4 MPa.
Δ Ideal for applications where severe scaling is a concern, ensuring reliable performance.
Δ Perfect for scenarios where pipes are prone to corrosion, extending the equipment's lifespan.
