Detailed Descriptions of NOBLEST's Diverse Tube Heat Exchangers
1. Shell and Tube Heat Exchanger / Fixed Tube and Sheet Heat Exchanger:
NOBLEST Shell and Tube Heat Exchanger This fixed tube-plate heat exchanger consists of a tube plate and a shell at both ends, boasting a widely utilized, simplistic structure. In this tube and shell heat exchanger, the tube plates at both ends of the bundle are welded to the shell. Post-welding, the tube plate can serve as a flange, connecting with the pipe box flange via bolts.
Applications: As an energy-saving apparatus facilitating material heat transfer, it finds extensive use in petroleum, chemical, petrochemical, metallurgy, electric power, light industry, and food sectors. With expanding energy-saving technologies, the use of heat exchangers for high and low temperature heat recovery brings significant economic benefits.
The Advantage Its strength lies in its simple structure, ensuring the minimum inner diameter of the shell while retaining an equivalent heat transfer surface. However, a significant temperature disparity between the shell and pipe medium can lead to thermal stress, potentially causing pipe and tube plate failures, leaks, or instability. Additionally, maintenance and shell cleaning processes are inconvenient. Despite widespread general use, this design is temperature-difference limited.
2. U-Shaped Style Tube Heat Exchanger
NOBLEST U-Shaped Type Tube Heater This shell and tube heat exchanger, part of petrochemical equipment, comprises main components such as a tube box, shell, and tube bundle. It features a single tube plate with both pipe ends fixed to it.
The Main Features :
Δ The tube bundle can freely expand and contract, preventing thermal stress from temperature differences between the tube and shell.
Δ Excellent thermal compensation performance.
Δ The double-tube flow on the shell side offers a longer flow path and higher velocity, enhancing heat transfer performance.
Δ High pressure resistance.
Δ The tube bundle can be withdrawn from the shell for easy maintenance and cleaning, making it a cost-effective and straightforward structure.
Applications:
Ideal for conditions with a large temperature difference between tube and shell walls or where the shell-side medium tends to scale while the tube-side medium remains clean, less prone to scaling, high temperature, high pressure, and strong corrosive environments.
3. Floating Head Tube Heat Exchanger
NOBLEST Floating Head Heat Exchanger features one fixed tube plate end and a freely moving floating head end, comprising a floating tube plate, hook ring, and floating head end cover. The detachable design allows the tube bundle to be drawn from the shell, avoiding thermal stress from tube bundle and shell deformation.
Features:
Convenient tube-to-tube cleaning and elimination of thermal stress are key advantages. However, its complex structure, higher cost compared to fixed tubeplate heat exchangers, bulkiness, and high material consumption, along with the inability to check the small floating head cover during operation and higher sealing requirements in manufacturing, are notable drawbacks. It's best suited for scenarios with significant wall temperature differences between the shell and the tube bundle or where the shell medium is prone to scaling.
Applications:
Δ The tube bundle is ingeniously designed for effortless removal, ensuring easy and thorough cleaning of both the tube and shell process;
Δ No limitations on the temperature differential between the mediums, providing versatile application;
Δ Capable of operating under extreme conditions, withstanding temperatures up to 450 degrees Celsius and pressures up to 6.4 MPa;
Δ Ideal for environments with severe scaling issues;
Δ Suitable for use in highly corrosive conditions, ensuring durability and longevity;
