An In-Depth Look at NOBLEST's Varied Tube Heat Exchanger Options
1. Shell and Tube Heat Exchanger/Fixed Tube and Sheet Heat Exchanger:
Introducing the NOBLEST Shell and Tube Heat Exchanger Our fixed tube-plate heat exchanger is ingeniously designed with a tube plate and a shell at both ends. This simplistic yet efficient structure makes it highly versatile. It features tube plates at both ends of the bundle, welded securely to the shell. The tube plate can also serve as a flange after welding with the shell, seamlessly connecting with the flange of the pipe box using bolts.
Applications: This energy-efficient marvel facilitates heat transfer between materials, finding extensive applications across a myriad of industries including petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food. As energy-saving technologies continue to evolve, the use of heat exchangers for high and low-temperature heat recovery has brought about substantial economic benefits.
Advantages and Disadvantages: The main advantage of this design is its simple structure, ensuring minimal inner diameter of the shell while maintaining effective heat transfer. However, it does face challenges such as thermal stress when significant temperature differences exist between the shell and pipe medium, which can lead to pipe and tube plate failures, leaks, or instability. Additionally, maintenance and cleaning of the shell can be cumbersome. Despite these limitations, it remains widely used in general applications, though it is constrained by temperature differences.
2. U-Shaped Style Tube Heat Exchanger
Introducing the NOBLEST U-Shaped Type Tube Heater This innovative shell and tube heat exchanger, a staple in petrochemical equipment, features key components such as a tube box, shell, and tube bundle. Uniquely, the U-shaped tube heat exchanger has only one tube plate, with both ends of the pipe fixed on the same plate.
Main Features: :
Δ The tube bundle can freely expand and contract without generating thermal stress due to temperature differences between the tube and shell,
Δ Excellent thermal compensation performance;
Δ The shell side employs a double-tube flow with a longer path and higher flow velocity, enhancing heat transfer performance;
Δ High pressure resistance;
Δ The tube bundle is easily withdrawable from the shell for maintenance and cleaning, offering a simple and cost-effective structure.
Applications:
Ideal for scenarios where there is a significant temperature difference 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 prone to scaling. It is also suitable for high-temperature, high-pressure, and highly corrosive conditions.
3. Floating Head Tube Heat Exchanger
Introducing the NOBLEST Floating Head Heat Exchanger This equipment features one end of the two tube plates fixed to the shell, while the other end moves freely relative to the shell, known as the floating head. The floating head comprises a floating tube plate, a hook ring, and a floating head end cover, all of which are detachable. The tube bundle can be withdrawn from the shell, and the thermal deformation of the tube bundle and shell are unconstrained, eliminating thermal stress.
Features:
Advantages include convenient cleaning between tubes and absence of thermal stress. However, the structure is complex and more costly than fixed tube-plate heat exchangers. It is bulkier, consumes more material, and requires high sealing standards during manufacturing. Despite these complexities, it is well-suited for scenarios with significant temperature differences between the shell and tube bundle or when the shell medium is prone to scaling.
Applications:
Δ The tube bundle is designed for effortless removal, ensuring easy and thorough cleaning of both the tube and shell processes.
Δ No limitations on the temperature difference between media, providing versatile and flexible application.
Δ Engineered to withstand extreme conditions, capable of operating under high temperatures up to 450 degrees Celsius and pressures up to 6.4 MPa, ensuring robust performance under demanding circumstances.
Δ Ideal for use in environments prone to severe scaling, maintaining efficiency and reliability.
Δ Perfectly suited for applications where pipe corrosion is a concern, offering durable and long-lasting performance.
