Detailed Descriptions of NOBLEST's Varied Tube Heat Exchanger Models
1. Shell and Tube Heat Exchanger / Fixed Tube and Sheet Heat Exchanger:
NOBLEST Shell and Tube Heat Exchanger The fixed tube-plate heat exchanger is renowned for its simplistic and robust design. It consists of a tube plate and a shell at both ends, making it widely utilized. In this model, the tube plates at both ends of the bundle are welded to the shell. The tube plate can also function as a flange after welding with the shell and is connected to the flange of the pipe box by bolts.
Applications: This energy-efficient equipment is essential for heat transfer between materials, extensively applied in industries such as petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food. With the continuous expansion of energy-saving technology applications, the utilization of these heat exchangers for high and low-temperature heat recovery has yielded significant economic benefits.
Advantages and Disadvantages Advantages: The fixed tube-plate heat exchanger boasts a simple structure, ensuring the minimum inner diameter of the shell while maintaining the same heat transfer surface. Disadvantages: A significant temperature difference between the shell and pipe medium can lead to thermal stress, causing pipe and tube plate failure, leakage, or instability. Additionally, maintenance and cleaning processes for the shell are inconvenient. This design is widely used in general applications but limited by temperature differences.
2. U-Shaped Style Tube Heat Exchanger
NOBLEST U-Shaped Type Tube Heater This model is a type of shell and tube heat exchanger, belonging to petrochemical equipment. It is composed of main components such as the tube box, shell, and tube bundle. The U-shaped tube heat exchanger has only one tube plate, with both ends of the pipe fixed on the same tube plate.
Main Features :
Δ The tube bundle can freely expand and contract without generating thermal stress due to the temperature difference between the tube and shell.
Δ Excellent thermal compensation performance.
Δ The shell side features a double-tube flow, providing a longer flow path and higher flow velocity, resulting in superior heat transfer performance.
Δ High pressure resistance.
Δ The tube bundle can be easily withdrawn from the shell for maintenance and cleaning. Its simple and cost-effective structure adds to its appeal.
Applications:
Ideal for situations with significant temperature differences between the tube and shell walls, or where the shell-side medium is prone to scaling while the tube-side medium remains clean and less prone to scaling. This model excels under high temperature, high pressure, and strongly corrosive conditions.
3. Floating Head Tube Heat Exchanger
NOBLEST Floating Head Heat Exchanger This model features one end of the tube plate fixed with the shell, while the other end can move freely relative to the shell, known as the floating head. The floating head comprises a floating tube plate, a hook ring, and a floating head end cover. The design is detachable, and the tube bundle can be extracted from the shell. This ensures no thermal stress as the thermal deformation of the tube bundle and the shell are not constrained.
Features:
Advantages: Easy cleaning between tubes, and no thermal stress generation. Disadvantages: Its structure is more complex and costly than the fixed tubeplate heat exchanger. The equipment is bulky, consumes more material, and the floating head's small cover cannot be checked during operation, requiring higher manufacturing sealing standards. It is suitable for scenarios with significant wall temperature differences between the shell and the tube bundle or when the shell medium is prone to scaling.
Applications:
Δ The tube bundle can be effortlessly drawn out, making the cleaning process of both the tube and shell seamless and hassle-free;
Δ There are no restrictions on the temperature difference between the mediums, allowing for versatile application scenarios;
Δ Designed to operate under high temperature and high-pressure conditions, withstanding up to 450 degrees Celsius and pressures up to 6.4 MPa, ensuring robust performance;
Δ Ideal for use in environments with severe scaling, offering reliable and long-lasting efficiency;
Δ Perfectly suited for applications where pipes are prone to corrosion, providing durable and dependable service;
