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 features a tube plate and shell at both ends, making it widely utilized for its simplistic structure. This type of heat exchanger has the tube plates at both ends welded to the shell. The welded tube plate can also function as a flange, connecting with the pipe box flange by bolts.
Applications: Serving as an energy-saving device, it facilitates heat transfer between materials, finding extensive application in industries such as petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food. With the growing implementation of energy-saving technologies, heat exchangers for high and low-temperature heat recovery have yielded significant economic benefits.
Advantages: The design’s strength lies in its simple structure, ensuring the minimum inner diameter of the shell while maintaining the same heat transfer surface. However, it faces a significant disadvantage when there is a large temperature difference between the shell and pipe medium, leading to thermal stress that can cause pipe and tube plate failure, leakage, or instability. Additionally, maintenance and cleaning of the shell can be inconvenient. Although widely used in general applications, this design is limited by temperature differences.
2. U-Shaped Tube Heat Exchanger
NOBLEST U-Shaped Tube Heater A type of shell and tube heat exchanger, this equipment belongs to the petrochemical sector and 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.
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 has 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 removed from the shell for maintenance and cleaning, with a simple and cost-effective structure.
Applications:
Ideal for situations where there is a large temperature difference between the tube and shell walls, or where the shell-side medium is prone to scaling while the tube-side medium is 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 In this design, only one end of the tube plate is fixed to the shell, while the other end can move freely relative to the shell, known as the floating head. The floating head consists of a floating tube plate, hook ring, and floating head end cover. It is detachable, allowing the tube bundle to be drawn from the shell without generating thermal stress.
Features:
Its key advantages include convenient cleaning between tubes, and the absence of thermal stress. Conversely, its complexity and higher cost compared to fixed tube-plate heat exchangers are notable drawbacks. The equipment is bulky, consumes more material, and demands higher sealing requirements during manufacturing. It is suitable for scenarios with a large wall temperature difference between the shell and tube bundle or where the shell medium is prone to scaling.
Applications:
Δ The innovative design allows the tube bundle to be effortlessly drawn out, ensuring ease of cleaning for both the tube and shell processes;
Δ Flexible operation with no limitations on the temperature difference between the mediums;
Δ Engineered to endure high temperatures and pressures, withstanding up to 450 degrees Celsius and pressures of up to 6.4 MPa;
Δ Ideally suited for applications with severe scaling conditions;
Δ Perfect for use in environments where pipe corrosion is a significant concern.
