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 The Fixed Tube-Plate Heat Exchanger by NOBLEST is engineered with a tube plate and a shell at both ends, making it highly sought after for its straightforward design. This type of heat exchanger is constructed such that the tube plates at both ends are welded to the shell. The tube plate can also double as a flange post-welding and is bolted to the pipe box flange.
Applications: As a premier energy-saving apparatus, this heat exchanger optimizes heat transfer between various materials. It is extensively utilized across industries such as petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food. With the ongoing growth of energy-efficient technologies, the application of heat exchangers for both high and low-temperature heat recovery has delivered substantial economic benefits.
The Advantage The Fixed Tube and Sheet Heat Exchanger boasts a simplistic structure, reducing the shell's inner diameter while preserving the heat transfer surface. Despite its wide usage, it presents challenges such as thermal stress due to significant temperature differences between the shell and pipe medium. This can lead to pipe and tube plate failure, leakage, or instability. Maintenance and cleaning within the shell are also cumbersome.
2. U-Shaped Style Tube Heat Exchanger
NOBLEST U-Shaped Type Tube Heater A specialized shell and tube heat exchanger, the U-shaped heat exchanger is vital petrochemical equipment, comprising a tube box, shell, and tube bundle. It features a single tube plate, with both pipe ends secured to the same tube plate.
Main Features :
Δ The tube bundle can expand and contract freely, eliminating thermal stress from temperature differences between the tube and shell.
Δ Exceptional thermal compensation performance.
Δ The shell side features a double-tube flow, offering an extended flow path and higher flow velocity, thus enhancing heat transfer efficiency.
Δ High resistance to pressure.
Δ The tube bundle is removable for straightforward maintenance and cleaning, with a simple and cost-effective structure.
Applications:
Ideal for scenarios with significant temperature differences between the tube and shell walls, or where the shell-side medium tends to scale while the tube-side medium remains clean with minimal scaling, even under high temperature, high pressure, and strongly corrosive conditions.
3. Floating Head Tube Heat Exchanger
NOBLEST Floating Head Heat Exchanger In this design, only one end of the tube plate is fixed to the shell, allowing the other end to move freely relative to the shell — a feature termed the floating head. This structure comprises a floating tube plate, a hook ring, and a floating head end cover, all of which are detachable. The tube bundle can be removed from the shell, preventing thermal stress from constraining thermal deformation of the tube bundle and shell.
Features:
Key advantages include easy cleaning between tubes and the absence of thermal stress. However, the complex structure increases costs compared with fixed tube-plate heat exchangers. The equipment is more substantial, requires more materials, and demands higher sealing standards during manufacturing. The small cover of the floating head cannot be inspected during operation. It is perfect for situations where there are significant temperature differences between the shell and tube bundle walls or where the shell medium is prone to scaling.
Applications:
Δ The tube bundle of our Fixed Tube and Sheet Heat Exchanger can be effortlessly drawn out, greatly simplifying the cleaning process for both the tube and the shell.
Δ Experience unmatched flexibility with our heat exchanger, as it handles any temperature difference between media without limitations.
Δ Engineered to perform in extreme conditions, our heat exchanger operates efficiently under high temperature and high pressure, with a maximum temperature of 450 degrees and pressure up to 6.4 MPa.
Δ Ideal for challenging environments, our heat exchanger is designed to excel in conditions with serious scaling issues.
Δ Perfect for applications involving pipes susceptible to corrosion, ensuring long-lasting durability and reliability.
