Descriptions of NOBLEST Different Type Tube Heat Exchanger
1. Shell and Tube Heat Exchanger/Fixed Tube and Sheet Heat Exchanger:
NOBLEST Shell and Tube Heat Exchanger The fixed tube-plate heat exchanger from NOBLEST consists of a tube plate and a shell at both ends, making it widely utilized due to its simplistic structure. This design features tube plates at both ends of the bundle welded to the shell. The welded tube plate can also function as a flange, connecting with the flange of the pipe box via bolts. This straightforward construction makes it a popular choice.
Applications: This versatile equipment facilitates heat transfer between materials and is extensively applied in industries such as petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food. With the ongoing expansion of energy-saving technologies, the use of heat exchangers for high and low-temperature heat recovery has delivered significant economic benefits.
The Advantage is its simple structure, ensuring the minimal inner diameter of the shell while maintaining the same heat transfer surface. However, a notable drawback is the potential for thermal stress when there is a significant temperature difference between the shell and pipe medium, which can lead to pipe and tube plate failure, leakage, or instability. Maintenance and cleaning processes for the shell are also inconvenient. While widely used in general applications, this design is limited by temperature differences.
2. U-Shaped Style Tube Heat Exchanger
NOBLEST U-Shaped Type Tube Heater This type of shell and tube heat exchanger, classified as petrochemical equipment, is composed of main components such as a tube box, shell, and tube bundle. The U-shaped tube heat exchanger features only one tube plate, with both ends of the pipe fixed on the same tube plate.
The Main Features :
Δ The tube bundle can freely expand and contract without generating thermal stress due to temperature differences between the tube and shell,
Δ Excellent thermal compensation performance;
Δ The shell side comprises a double-tube flow with a longer flow path and higher flow velocity, resulting in superior heat transfer performance;
Δ High pressure resistance;
Δ The tube bundle can be extracted from the shell for maintenance and cleaning, offering a simple and cost-effective structure.
Applications:
Ideal for scenarios where there is a large temperature difference between the tube and shell walls, or where the shell-side medium is likely to scale while the tube-side medium remains clean and less prone to scaling. Suitable for high temperature, high pressure, and highly corrosive conditions.
3. Floating Head Tube Heat Exchanger
NOBLEST Floating Head Heat Exchanger Features a design where only one end of the tube plate is fixed to the shell, allowing the other end to move freely relative to the shell, hence the name 'floating head.' This floating head comprises a floating tube plate, a hook ring, and a floating head end cover, all detachable. Consequently, the tube bundle can be drawn from the shell, and thermal deformation of the tube bundle and shell isn't restricted, eliminating thermal stress.
Features:
The primary advantages include easy cleaning between tubes, elimination of thermal stress, and flexibility in handling large wall temperature differences between the shell and tube bundle. However, its complex structure and higher cost compared to fixed tubeplate heat exchangers, along with larger equipment size and material consumption, are disadvantages. The small cover of the floating head is not accessible during operation, requiring higher sealing standards during manufacturing.
Applications:
Δ The tube bundle can be effortlessly removed, ensuring easy and thorough cleaning of both the tubes and the shell, making maintenance a breeze;
Δ This exchanger excels with an unrestricted temperature differential between mediums, offering unmatched versatility in various applications;
Δ Designed to withstand high-temperature and high-pressure conditions, it operates efficiently at temperatures up to 450 degrees Celsius and pressures up to 6.4 MPa, ensuring reliable performance in challenging environments;
Δ Ideal for applications with severe scaling conditions, maintaining optimal functionality where other solutions may fail;
Δ Perfectly suited for environments prone to pipe corrosion, offering robust and durable performance.
