Comprehensive Descriptions of NOBLEST's Diverse Tube Heat Exchanger Models
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 a marvel of engineering simplicity, comprising a tube plate and a shell at both ends. The tube plates at both ends of the bundle are securely welded to the shell, allowing the tube plate to function as a flange once integrated with the shell. This assembly is then bolted to the pipe box flange, making it highly versatile across various applications.
Applications: This energy-efficient device excels in facilitating heat transfer between materials and is indispensable in industries such as petroleum, chemicals, petrochemicals, metallurgy, electric power, light industry, and food. The growing adoption of energy-saving technologies has significantly boosted the economic benefits derived from high and low-temperature heat recovery using NOBLEST heat exchangers.
Advantages: The primary advantage of this design is its straightforward structure, which ensures the minimum inner shell diameter while maintaining an optimal heat transfer surface. However, significant temperature differences between the shell and pipe medium can induce thermal stress, potentially causing tube plate failure, leakage, or instability. Additionally, maintenance and cleaning can be challenging, which limits its usage in applications with varied temperature ranges.
2. U-Shaped Tube Heat Exchanger
NOBLEST U-Shaped Tube Heat Exchanger This type of shell and tube heat exchanger, typically used in petrochemical equipment, features key components such as a tube box, shell, and tube bundle. The U-shaped configuration involves a single tube plate, with both ends of the pipe securely attached to it.
Main Features: :
Δ The tube bundle can expand and contract freely, eliminating thermal stress due to temperature differences.
Δ Exceptional thermal compensation performance.
Δ The shell side features a double-tube flow, resulting in a longer flow path and elevated flow velocity, enhancing heat transfer efficiency.
Δ High pressure resistance.
Δ The tube bundle can be easily withdrawn from the shell for maintenance and cleaning, offering a simple and cost-effective design.
Applications:
Ideal for scenarios with significant temperature differences between the tube and shell walls, or where the shell-side medium is prone to scaling while the tube-side remains clean. It performs exceptionally well under conditions of high temperature, high pressure, and strong corrosion.
3. Floating Head Tube Heat Exchanger
NOBLEST Floating Head Heat Exchanger This advanced design features a floating head, where one end of the tube plate is fixed to the shell and the other end can move freely. The floating head assembly includes a floating tube plate, hook ring, and floating head end cover, all of which are detachable, allowing the tube bundle to be easily removed from the shell. This design eliminates thermal stress and permits free thermal deformation of the tube bundle and shell.
Features:
The floating head design offers easy cleaning between tubes and eliminates the risk of thermal stress. However, it comes with a more complex structure and higher costs compared to fixed tube-plate heat exchangers. The equipment is bulkier, consumes more material, and requires higher sealing standards. It is ideal for applications with large temperature differences between the shell and tube bundle or where the shell medium tends to scale.
Applications:
Δ The tube bundle can be effortlessly drawn out, ensuring seamless cleaning and maintenance of both the tube and shell process.
Δ This equipment operates efficiently regardless of the temperature difference between mediums.
Δ Designed for rigorous conditions, it performs exceptionally well under high temperature and pressure, withstanding up to 450 degrees and 6.4 MPa.
Δ Ideal for challenging applications where serious scaling is a concern.
Δ Perfect for environments prone to pipe corrosion, offering robust and reliable performance.
