Comprehensive Descriptions of NOBLEST’s Distinct Tube Heat Exchangers
1. Shell and Tube Heat Exchanger / Fixed Tube and Sheet Heat Exchanger:
NOBLEST Shell and Tube Heat Exchangers This model features a fixed tube-plate design, consisting of a tube plate and a shell at both ends. Its simplistic structure makes it widely utilized. In this heat exchanger, the tube plates at both ends of the bundle are welded to the shell. The tube plate can also act as a flange after welding with the shell, allowing for bolt connections to the pipe box flange.
Applications: This heat exchanger functions as an energy-efficient solution for promoting heat transfer between materials. It finds extensive applications across a variety of industries including petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food. The expansion of energy-saving technologies has significantly boosted the economic benefits from high and low-temperature heat recovery.
Advantages: Its simple structure ensures the minimum inner diameter of the shell while maintaining an effective heat transfer surface. However, significant temperature differences between the shell and pipe medium may induce thermal stress, potentially leading to pipe and tube plate failure, leakage, or instability. Additionally, maintenance and cleaning of the shell can be inconvenient. Despite these limitations, it remains widely used in general applications.
2. U-Shaped Style Tube Heat Exchanger
NOBLEST U-Shaped Type Tube Heater This type of shell and tube heat exchanger, designed for petrochemical applications, comprises main components such as a tube box, shell, and tube bundle. The U-shaped tube heat exchanger features a single tube plate, with both ends of the tubes fixed to the same plate.
Main Features :
Δ The tube bundle can freely expand and contract, eliminating 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, thereby enhancing heat transfer performance;
Δ High pressure resistance;
Δ The tube bundle can be easily withdrawn from the shell for maintenance and cleaning. The structure is simple and cost-effective.
Applications:
Ideal for scenarios involving significant 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 scale-resistant. It is suitable for high temperature, high pressure, and highly corrosive environments.
3. Floating Head Tube Heat Exchanger
NOBLEST Floating Head Heat Exchanger 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, known as the floating head. The floating head consists of a floating tube plate, a hook ring, and a floating head end cover. It is detachable, allowing the tube bundle to be extracted from the shell. This configuration prevents thermal stress by accommodating differential thermal expansion.
Features:
Advantages include easy cleaning between tubes, and the elimination of thermal stress. However, the structure is complex, more costly than fixed tube-plate designs, and bulky with higher material consumption. The small cover of the floating head cannot be inspected during operation, and higher sealing requirements are needed during manufacturing. It is suitable for applications with significant temperature differences between the shell and tube bundle walls, or where the shell medium is prone to scaling.
Applications:
Δ The tube bundle can be easily extracted, simplifying the cleaning process for both the tube and shell components, ensuring long-lasting efficiency.
Δ There are no limitations on the temperature difference between the mediums, offering unmatched flexibility in various applications.
Δ Capable of operating under extreme conditions, it functions efficiently at temperatures up to 450 degrees Celsius and pressures up to 6.4 MPa, making it highly adaptable for demanding environments.
Δ Perfectly suited for conditions with significant scaling, providing reliable performance where other heat exchangers may fail.
Δ Ideal for environments prone to pipe corrosion, offering robust and durable service.
