Comprehensive Descriptions of NOBLEST's Diverse Types of Tube Heat Exchangers
1. Shell and Tube Heat Exchanger/Fix Tube and Sheet Heat Exchanger:
NOBLEST Shell and Tube Heat Exchanger This variant is the fixed tube-plate heat exchanger. It features a straightforward yet highly effective design comprising a tube plate and shell at both ends, making it a preferred choice across numerous applications. In this type, the tube plates at both ends are securely welded to the shell, ensuring robust construction. Additionally, the tube plate can function as a flange post-welding, bolted to the pipe box flange for enhanced connectivity.
Applications: It acts as a remarkable energy-saving device, enabling efficient heat transfer between different materials. This makes it indispensable across a spectrum of industries such as petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food processing. With the growing adoption of energy-saving technologies, heat exchangers play a pivotal role in high and low-temperature heat recovery, delivering substantial economic benefits.
Advantages Its primary advantage lies in its uncomplicated design, which ensures the minimal inner diameter of the shell while maintaining an optimal heat transfer surface. However, a significant drawback emerges when there's a considerable temperature differential between the shell and pipe medium, which may induce thermal stress, potentially leading to pipe and tube plate failure, leakage, or instability. Furthermore, maintenance and cleaning of the shell can be challenging. Despite its widespread use in standard applications, temperature variations limit its effectiveness.
2. U-shaped Style Tube Heat Exchanger
NOBLEST U-shaped Type Tube Heater This model is a shell and tube heat exchanger, classified as petrochemical equipment, comprising essential components such as the tube box, shell, and tube bundle. The distinctive U-shaped tube heat exchanger features a single tube plate, with both ends of the pipe fixed to this singular tube plate.
Main Features :
Δ The tube bundle can freely expand and contract without inducing thermal stress due to the temperature differential between the tube and shell,
Δ Excellent thermal compensation performance;
Δ The shell side has a double-tube flow design, providing a longer flow path and higher velocity for superior heat transfer performance;
Δ High pressure resistance;
Δ The tube bundle is easily removable from the shell for maintenance and cleaning, featuring a simple and cost-effective design.
Applications:
This type is ideal for scenarios where there is a substantial temperature difference between the tube and shell walls, or when the shell-side medium is prone to scaling or the tube-side medium is clean and less likely to scale. It is also suitable for high-temperature, high-pressure, and highly corrosive conditions.
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, while the other end can move freely relative to the shell, known as the floating head. The floating head assembly includes a floating tube plate, a hook ring, and a floating head end cover. Its detachable nature allows the tube bundle to be drawn from the shell, eliminating thermal stress as the tube bundle and shell are not constrained by thermal deformation.
Features:
The key benefits include easy cleaning between tubes, and the absence of thermal stress. However, it features a complex structure and higher costs compared to fixed tube-plate heat exchangers. It is also bulkier, with higher material consumption, and the floating head's small cover cannot be inspected during operation. Additionally, it demands higher sealing standards during manufacturing. It is ideal for situations involving significant wall temperature differences between the shell and tube bundle or when the shell medium is prone to scaling.
Applications:
Δ The innovative tube bundle design allows for easy extraction, simplifying the cleaning process for both the tube and shell, ensuring optimal maintenance and longevity;
Δ Our heat exchanger offers unmatched versatility with no limitations on the temperature difference between mediums, ensuring maximum efficiency for diverse applications;
Δ Engineered to withstand extreme conditions, it operates seamlessly under high temperatures up to 450 degrees Celsius and pressures up to 6.4 MPa, delivering reliable performance in demanding environments;
Δ Ideal for challenging conditions, our system efficiently handles severe scaling, maintaining robust functionality and durability;
Δ Designed for durability, it excels in environments where pipe corrosion is a concern, offering extended service life and reliability;
