Detailed Descriptions of NOBLEST's Varied Tube Heat Exchanger Types
1. Shell and Tube Heat Exchanger/Fixed Tube and Sheet Heat Exchanger:
NOBLEST Shell and Tube Heat Exchanger The fixed tube-plate heat exchanger features a straightforward design, consisting of a tube plate welded to a shell at both ends. This design is notable for its simplicity and broad utilization. The tube plate, once welded to the shell, can be employed as a flange and connected to the pipe box flange by bolts, enhancing its versatility.
Applications: As an energy-efficient solution, it excels in facilitating heat transfer across various materials. Its applications span multiple industries, including petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food processing. With advancements in energy-saving technologies, heat exchangers have driven substantial economic benefits through high and low temperature heat recovery.
Advantages and Considerations: The design's primary advantage lies in its structural simplicity, maintaining a minimal inner shell diameter while ensuring effective heat transfer. However, a significant temperature difference between the shell and pipe medium can generate thermal stress, potentially causing pipe and tube plate failure, leakage, or instability. Moreover, maintenance and cleaning of the shell can be challenging, limiting this design's application in environments with substantial temperature variations.
2. U-Shaped Tube Heat Exchanger:
NOBLEST U-Shaped Style Tube Heater This type of shell and tube heat exchanger is a staple in petrochemical equipment. Key components include the tube box, shell, and tube bundle. Notably, the U-shaped design features a single tube plate with both pipe ends affixed to it.
Distinct Features: :
Δ Tube bundles can expand and contract freely, negating thermal stress from temperature differences.
Δ Superior thermal compensation capabilities.
Δ Double-tube flow on the shell side ensures a prolonged flow path and higher flow velocity, enhancing heat transfer efficiency.
Δ High resistance to pressure.
Δ Easy maintenance and cleaning with removable tube bundles, coupled with a simple and cost-effective structure.
Applications:
Ideal for scenarios with significant temperature differences between tube and shell walls, or when the shell-side medium is prone to scaling while the tube-side medium remains clean. It performs well under high temperature, high pressure, and corrosive conditions.
3. Floating Head Tube Heat Exchanger:
NOBLEST Floating Head Heat Exchanger This exchanger features a unique design where only one tube plate end is fixed to the shell, allowing the other end to move freely. This 'floating head' comprises a floating tube plate, hook ring, and floating head end cover, all detachable. This design eliminates thermal stress by allowing independent thermal deformation of the tube bundle and shell.
Features:
The floating head exchanger offers ease of cleaning between tubes and tubes while preventing thermal stress. However, its complex structure and higher cost compared to fixed tubeplate heat exchangers make it bulky and material-intensive. Additionally, the small floating head cover's inspection during operation is challenging, and manufacturing demands high sealing standards. It is particularly suited for applications with considerable wall temperature differences or when the shell medium is prone to scaling.
Applications:
Δ The innovative design allows the tube bundle to be easily drawn out, significantly simplifying the cleaning process for both the tube and shell.
Δ Our heat exchanger boasts an unrestricted temperature difference between mediums, offering unparalleled flexibility in various applications.
Δ Engineered to perform under extreme conditions, it operates efficiently at high temperatures up to 450 degrees and pressures up to 6.4 MPa.
Δ Ideal for environments with severe scaling, ensuring reliable and long-lasting performance.
Δ Perfectly suited for applications involving highly corrosive substances, extending the lifespan of your equipment.
