Explore the Diverse Range of NOBLEST 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 by NOBLEST is a marvel of engineering, comprising a tube plate and a shell at both ends. This design is celebrated for its simplicity and widespread usage. It features a tube and shell configuration where the tube plates at both ends of the bundle are meticulously welded to the shell. The tube plate can double as a flange post-welding, and is bolted to the flange of the pipe box, offering ease of connection and robustness.
Applications: This energy-efficient equipment facilitates seamless heat transfer between materials, playing a pivotal role in industries such as petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food processing. As energy-saving technologies continue to advance, the role of heat exchangers in high and low-temperature heat recovery has ushered in remarkable economic benefits.
Advantages: The standout feature of this design is its simplicity, which ensures the minimum inner diameter of the shell while maintaining a substantial heat transfer surface. However, a significant drawback is the thermal stress that can occur when there is a major temperature difference between the shell and pipe medium, potentially causing pipe and tube plate failure, leakage, or instability. Additionally, maintenance and cleaning of the shell can be cumbersome. Despite its wide usage in general applications, its design is somewhat limited by temperature discrepancies.
2. U-shaped Style Tube Heat Exchanger
NOBLEST U-shaped Type Tube Heater This variant of shell and tube heat exchanger, integral to petrochemical equipment, consists of key components like the tube box, shell, and tube bundle. The U-shaped tube heat exchanger is unique with its single tube plate, where both ends of the pipe are fixed on the same tube plate.
Key Features: :
Δ The tube bundle can expand and contract freely without incurring 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 increased flow velocity, thereby enhancing heat transfer efficiency,
Δ High-pressure resistance,
Δ The tube bundle can be easily withdrawn from the shell for maintenance and cleaning, ensuring simplicity and cost-effectiveness.
Applications:
Ideal for scenarios where the temperature difference between tube and shell walls is substantial, or where the shell-side medium tends to scale while the tube-side medium remains clean and less prone to scaling. It is also suitable for high-temperature, high-pressure, and highly corrosive conditions.
3. Floating Head Tube Heat Exchanger
NOBLEST Floating Head Heat Exchanger is designed with innovation, featuring one end of the tube plate fixed to the shell while the other end moves freely relative to the shell, known as the floating head. This configuration includes a floating tube plate, a hook ring, and a floating head end cover, all of which can be detached. This allows the tube bundle to be extracted from the shell, eliminating thermal stress by accommodating thermal deformation of the tube bundle and shell independently.
Features:
Advantages include effortless cleaning between tubes, and the absence of thermal stress. However, its intricate structure and higher material consumption make it costlier than fixed tube-plate heat exchangers. Additionally, the equipment is bulkier, and inspection of the floating head’s small cover during operation is not feasible, necessitating higher sealing standards during manufacture. This design is best suited for scenarios with significant wall temperature differences between the shell and tube bundle or where the shell medium is prone to scaling.
Applications:
Δ The tube bundle can be easily extracted to streamline the cleaning process for both the tube and shell;
Δ Capable of handling any temperature difference between mediums without restriction;
Δ Designed for high-temperature and high-pressure operations, withstanding conditions up to 450 degrees Celsius and pressures up to 6.4 MPa;
Δ Suitable for environments with severe scaling issues;
Δ Ideal for applications involving easily corroded pipes.
