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 Our fixed tube-plate heat exchanger is renowned for its simple yet highly effective design. It features tube plates welded to the shell at both ends, which can also serve as flanges when connected to the pipe box with bolts. This configuration is widely adopted due to its straightforward structure, making it highly versatile and reliable.
Applications: This energy-efficient equipment significantly enhances heat transfer between materials. It is extensively employed across various industries, including petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food processing. With the ongoing advancements in energy-saving technologies, this heat exchanger has proven to deliver remarkable economic benefits through efficient high and low-temperature heat recovery.
Advantages: The simple structure of our heat exchanger allows for the smallest possible inner shell diameter while maintaining optimal heat transfer surfaces. However, a significant temperature difference between the shell and pipe medium may result in thermal stress, potentially causing pipe and tube plate failure, leakage, or instability. Additionally, maintenance and cleaning of the shell can be challenging, and the design is limited by temperature differences.
2. U-Shaped Tube Heat Exchanger
NOBLEST U-Shaped Tube Heat Exchanger This type of shell and tube heat exchanger is integral to petrochemical equipment, consisting of a tube box, shell, and tube bundle. Characterized by a single tube plate with both ends of the pipe fixed on it, this design offers unique advantages.
Main Features: :
Δ The tube bundle can freely expand and contract without incurring thermal stress due to temperature differences between the tube and shell.
Δ Excellent thermal compensation performance.
Δ The double-tube flow on the shell side provides a longer flow path and higher flow velocity, enhancing heat transfer efficiency.
Δ High pressure resistance.
Δ The tube bundle is easily removable from the shell for maintenance and cleaning, making it a cost-effective solution.
Applications:
Ideal for scenarios involving significant temperature differences between the tube and shell walls or where the shell-side medium scales easily while the tube-side medium is cleaner. Suitable for high-temperature, high-pressure, and highly corrosive conditions.
3. Floating Head Tube Heat Exchanger
NOBLEST Floating Head Heat Exchanger This innovative design features one end of the tube plate fixed to the shell, while the other end remains free, allowing movement relative to the shell. Comprising a floating tube plate, hook ring, and floating head end cover, this detachable unit enables the tube bundle to be withdrawn from the shell, preventing any thermal stress.
Features:
Benefits include easy cleaning between tubes, elimination of thermal stress, and adaptability to significant wall temperature differences between the shell and tube bundle. However, its complex structure, higher cost, bulky size, and extensive material usage may pose challenges. The small cover of the floating head requires careful inspection during operation, and high sealing standards are necessary during manufacturing. It is best suited for conditions with large temperature differences or where the shell medium is prone to scaling.
Applications:
Δ The innovative design allows the tube bundle to be effortlessly extracted, ensuring seamless cleaning of both the tube and shell, enhancing maintenance efficiency;
Δ The system is engineered to handle any temperature differential between mediums, providing unparalleled adaptability;
Δ Built to thrive under extreme conditions, it operates flawlessly at temperatures up to 450°C and pressures up to 6.4 MPa;
Δ Ideal for environments prone to significant scaling, ensuring long-lasting performance and reliability;
Δ Specifically designed for applications where the pipes are susceptible to corrosion, offering robust protection;
