Descriptions of NOBLEST's Diverse Range of Tube Heat Exchangers
1. Shell and Tube Heat Exchanger / Fixed Tube and Sheet Heat Exchanger:
NOBLEST Shell and Tube Heat Exchanger The fixed tube-plate heat exchanger features a straightforward yet efficient design, composed of a tube plate and a shell at both ends. This configuration is highly favored due to its simplicity and robustness. The tube plates are welded to the shell at both ends, and after welding, the tube plate can serve as a flange. This flange is then bolted to the pipe box flange, ensuring a secure and reliable connection.
Applications: This energy-saving device excels at facilitating heat transfer between various materials, making it indispensable in industries such as petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food processing. As energy-saving technologies continue to evolve and expand, heat exchangers play a crucial role in high and low temperature heat recovery, delivering substantial economic benefits.
Advantages: The fixed tube-plate heat exchanger stands out for its simple structure, which minimizes the shell's inner diameter while maintaining an effective heat transfer surface. However, it's important to note the potential drawbacks: significant temperature differences between the shell and tube may induce thermal stress, potentially leading to failure, leakage, or instability. Additionally, maintenance and cleaning of the shell can be challenging. While widely used, this design is best suited for applications with smaller temperature disparities.
2. U-Shaped Style Tube Heat Exchanger
NOBLEST U-Shaped Type Tube Heater This shell and tube heat exchanger, integral to petrochemical equipment, comprises essential components such as a tube box, shell, and tube bundle. The unique U-shaped design features a single tube plate with both ends fixed on it, ensuring effective heat exchange.
Main Features: :
Δ The tube bundle can expand and contract freely, mitigating thermal stress caused by temperature differences between the tube and shell.
Δ Excellent thermal compensation performance;
Δ The shell side features a double-tube flow, providing a longer flow path and higher flow velocity, which enhances heat transfer performance;
Δ High pressure resistance;
Δ The tube bundle can be easily withdrawn from the shell for maintenance and cleaning, adding to the structure's simplicity and cost-effectiveness.
Applications:
Ideal for scenarios involving significant temperature differences between tube and shell walls, or where the shell-side medium tends to scale while the tube-side medium remains clean. Suitable for high temperature, high pressure, and highly corrosive conditions.
3. Floating Head Tube Heat Exchanger
NOBLEST Floating Head Heat Exchanger This innovative heat exchanger design features one fixed tube plate at one end, while the other end, called the floating head, can move freely relative to the shell. The floating head assembly includes a floating tube plate, a hook ring, and a floating head end cover. This design is detachable, allowing the tube bundle to be easily withdrawn from the shell, ensuring there is no thermal stress as the tube bundle and shell can deform independently.
Features:
The floating head heat exchanger offers the advantage of easy cleaning between tubes and no thermal stress. However, its complex structure and higher cost compared to fixed tube-plate exchangers, along with larger size and material consumption, are considerations. The floating head's small cover cannot be inspected during operation, and higher sealing standards are required during manufacturing. It is ideal for applications with large temperature differences between the shell and tube bundle or where the shell medium tends to scale easily.
Applications:
Δ Effortless Maintenance: The innovative design allows the tube bundle to be easily drawn out, simplifying the cleaning process for both the tube and shell.
Δ Unlimited Temperature Difference: This product is engineered to handle any temperature differential between mediums without restriction.
Δ High-Performance Durability: Capable of operating under extreme conditions, this heater efficiently functions at temperatures up to 450 degrees and pressures up to 6.4 MPa.
Δ Versatile Applicability: Perfectly suited for environments with severe scaling, ensuring longevity and reliability.
Δ Corrosion Resistance: Specifically designed for environments where pipe corrosion is a concern, offering robust protection.
