Descriptions of NOBLEST Different Types 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 consists of a tube plate and a shell at both ends, making it highly sought after for its straightforward design. This type features tube plates at both ends of the bundle welded to the shell, doubling as flanges after welding, which are then bolted to the pipe box flange.
Applications: This heat exchanger excels as an energy-efficient solution for promoting heat transfer between materials, extensively applied in various industries such as petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food processing. With the ongoing adoption of energy-saving technologies, heat exchangers for high and low-temperature heat recovery have generated substantial economic advantages.
The Advantage of this design lies in its simple structure, maintaining the shell's minimum inner diameter while preserving the same heat transfer surface area. However, a significant drawback is its vulnerability to thermal stress caused by large temperature differences between the shell and pipe medium, potentially leading to pipe and tube plate failure, leakage, or instability. Moreover, maintenance and cleaning of the shell are cumbersome, making this design less favorable in applications with significant temperature variations.
2. U-shaped Style Tube Heat Exchanger
NOBLEST U-shaped Type Tube Heater is a specialized shell and tube heat exchanger commonly used in the petrochemical sector. It comprises principal components like 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 on the same plate.
The Main Features :
Δ The tube bundle can expand and contract freely, eliminating thermal stress due to temperature differences between the tube and shell.
Δ Excellent thermal compensation performance.
Δ Double-tube flow on the shell side offers a longer flow path and higher velocity, enhancing heat transfer efficiency.
Δ High pressure resistance.
Δ Easy maintenance and cleaning, as the tube bundle can be withdrawn from the shell. Simple and cost-effective structure.
Applications:
Ideal for conditions with substantial 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, suitable for high temperature, high pressure, and highly corrosive environments.
3. Floating Head Tube Heat Exchanger
NOBLEST Floating Head Heat Exchanger features a design where 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. It comprises a floating tube plate, hook ring, and a floating head end cover, all detachable, allowing the tube bundle to be removed from the shell to prevent thermal stress due to unrestricted thermal deformation.
Features:
Advantages include easy cleaning between tubes and no thermal stress generation. However, its complexity and higher manufacturing costs, bulky structure, significant material consumption, and the inability to inspect the floating head's small cover during operation, alongside higher sealing requirements, make it more suited for situations with considerable wall temperature differences or scaling-prone shell media.
Applications:
Δ The tube bundle can be effortlessly extracted, ensuring seamless cleaning of both tube and shell surfaces;
Δ Unrestricted by temperature differences, our design accommodates diverse medium conditions seamlessly;
Δ Capable of enduring extreme conditions, it operates efficiently under temperatures up to 450°C and pressures as high as 6.4 MPa;
Δ Perfectly suited for environments with severe scaling issues, providing uninterrupted performance;
Δ Ideal for applications involving high susceptibility to pipe corrosion, offering robust reliability;
