Descriptions of NOBLEST's Diverse Tube Heat Exchanger Solutions
1. Shell and Tube Heat Exchanger / Fixed Tube and Sheet Heat Exchanger:
NOBLEST Shell and Tube Heat Exchanger This robust fixed tube-plate heat exchanger consists of a tube plate and a shell at both ends, making it widely acclaimed for its simplicity. The tube plates at both ends of the bundle are welded to the shell, which can also serve as a flange after welding. This configuration allows for bolted connections with the pipe box flange, making it a highly efficient tube and shell heat exchanger.
Applications: As a premier energy-saving apparatus, it promotes efficient heat transfer between various materials and is extensively utilized across industries such as petroleum, chemical processing, petrochemicals, metallurgy, electric power, light industry, and the food sector. The expanding reach of energy-saving technologies has significantly amplified the economic advantages of heat exchangers in high and low-temperature heat recovery scenarios.
The Advantage This heat exchanger boasts a straightforward structure, optimizing the minimum inner diameter of the shell while preserving the same heat transfer surface area. However, a significant drawback is the potential development of thermal stress when there is a considerable temperature difference between the shell and the pipe medium. This stress can result in pipe and tube plate failure, leading to leakage or instability. Additionally, maintenance and cleaning of the shell can be cumbersome. Despite its broad application, the design's efficiency is somewhat restricted by temperature variations.
2. U-Shaped Style Tube Heat Exchanger
NOBLEST U-Shaped Type Tube Heater A sophisticated shell and tube heat exchanger belonging to petrochemical equipment, it comprises essential components such as the tube box, shell, and tube bundle. The U-shaped tube heat exchanger features a single tube plate, with both ends of the pipe securely fixed on the same tube plate.
Main Features :
Δ The tube bundle can freely expand and contract, eliminating thermal stress caused by temperature differences between the tube and shell.
Δ Excellent thermal compensation performance.
Δ The shell side operates with a double-tube flow, providing an extended 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Δ The tube bundle can be easily withdrawn from the shell for maintenance and cleaning, offering a simple and cost-effective structure.
Applications:
Ideal for scenarios with large 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 less susceptible 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 This advanced design features a floating head, where only one end of the tube plate is fixed to the shell, while the other end can move freely relative to the shell. The floating head comprises a floating tube plate, a hook ring, and a floating head end cover. This detachable configuration allows the tube bundle to be withdrawn from the shell, ensuring that thermal stress is non-existent due to the absence of constrained thermal deformation.
Features:
The floating head heat exchanger offers easy cleaning between tubes and eliminates the generation of thermal stress. However, it has a complex structure, is costlier than the fixed tube-plate heat exchanger, bulky, and has higher material consumption. Additionally, the small cover of the floating head cannot be inspected during operation and requires stringent sealing during manufacturing. It is suitable for situations with significant wall temperature differences between the shell and the tube bundle or where the shell medium is prone to scaling.
Applications:
Δ The tube bundle is designed for easy removal, simplifying the cleaning process for both the tube and shell sections;
Δ There are no limits on the temperature difference between the mediums, ensuring versatile application;
Δ Engineered to operate under extreme conditions, our product withstands high temperatures up to 450 degrees and pressures up to 6.4 mpa;
Δ Ideal for environments prone to severe scaling, maintaining performance and reliability;
Δ Perfectly suited for applications with a high risk of pipe corrosion, ensuring longevity and efficiency;
