Discover the Diverse Lineup of NOBLEST Tube Heat Exchangers
1. Shell and Tube Heat Exchanger/Fixed Tube and Sheet Heat Exchanger:
Introducing the NOBLEST Shell and Tube Heat Exchanger This robust fixed tube-plate heat exchanger features a simple yet highly effective design, consisting of tube plates and a shell at both ends. The tube plates are welded directly to the shell, which can also serve as a flange when combined with the pipe box flange using bolts. This straightforward structure makes it a popular choice across various industries.
Applications: The NOBLEST heat exchanger is a powerhouse of energy efficiency, facilitating optimal heat transfer between materials. It is extensively used in petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food sectors. As energy-saving technology continues to advance, the role of heat exchangers in high and low temperature heat recovery is driving substantial economic benefits.
Advantages: The primary advantage of this design lies in its simplicity, ensuring a minimal inner diameter of the shell while maintaining an efficient heat transfer surface. However, significant temperature differences between the shell and pipe medium can induce thermal stress, potentially leading to failures, leakage, or instability. Maintenance and cleaning of the shell can also be challenging. Despite these limitations, this design remains widely used in general applications.
2. U-Shaped Tube Heat Exchanger
Introducing the NOBLEST U-Shaped Tube Heater A sophisticated shell and tube heat exchanger, this model is integral to petrochemical processes, comprising key components such as a tube box, shell, and tube bundle. Unique to this design is the single tube plate that houses both ends of the U-shaped tubes.
Key Features: -
Δ The tube bundle can expand and contract freely, preventing thermal stress caused by temperature differences between the tube and shell.
Δ Exceptional thermal compensation performance.
Δ Double-tube flow on the shell side ensures a longer flow path and higher flow velocity, enhancing heat transfer efficiency.
Δ Superior high-pressure resistance.
Δ Easily removable tube bundle for straightforward maintenance and cleaning, coupled with a cost-effective, simple structure.
Applications:
Ideal for scenarios with large temperature differences between the tube and shell walls or where the shell-side medium tends to scale while the tube-side remains clean. Perfect for high-temperature, high-pressure, and highly corrosive conditions.
3. Floating Head Tube Heat Exchanger
Introducing the NOBLEST Floating Head Heat Exchanger This advanced model features a floating head mechanism, with only one end of the tube plate fixed to the shell. The other end moves freely, effectively eliminating thermal stress. The floating head assembly includes a floating tube plate, hook ring, and end cover—all detachable for easy maintenance, allowing the tube bundle to be withdrawn from the shell.
Features:
The major benefits include easy cleaning between tubes and stress-free thermal operation. However, this complex structure incurs higher costs, is bulkier, and requires more material. Also, the floating head's small cover cannot be inspected during operation, demanding higher sealing standards during manufacturing. This exchanger is best suited for applications with significant wall temperature differences or prone to shell-side scaling.
Applications:
Δ The tube bundle is designed for easy extraction, ensuring effortless cleaning of both the tube and shell, streamlining your maintenance process;
Δ There are no limitations on the temperature differential between the mediums, allowing for flexible and diverse applications;
Δ Engineered to operate under stringent conditions, our system performs efficiently at temperatures up to 450 degrees Celsius and pressures up to 6.4 MPa;
Δ Ideal for environments with significant scaling issues, providing reliable performance in challenging conditions;
Δ Suitable for applications where pipe corrosion is a concern, offering enhanced durability and longevity;
