Product Description
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 is fixed tube-plate heat exchanger,it consists of a tube plate and a shell at both ends, making it widely utilized due to its simplistic structure.It refers to a tube and shell heat exchanger in which the tube plates at both ends of the bundle are welded to the shell. The tube plate can also be used as a flange after welding with the shell, and is connected with the flange of the pipe box by bolts.

Applications: it serves as an energy-saving equipment for facilitating heat transfer between materials, finding extensive application 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 heat exchangers for high and low temperature heat recovery has yielded significant economic benefits.

The advantage lies in its simple structure, ensuring the minimum inner diameter of the shell while maintaining the same heat transfer surface. However, a notable disadvantage arises when there is a significant temperature difference between the shell and pipe medium, leading to thermal stress that may cause pipe and tube plate failure, leakage or instability. Additionally, maintenance and cleaning processes for the shell are inconvenient. Despite being 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 is a kind of shell and tube heat exchanger, which belongs to petrochemical equipment, is composed of main components such as tube box, shell and tube bundle. U-shaped tube heat exchanger has only one tube plate, and both ends of the pipe are fixed on the same tube plate.

The 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  good thermal compensation performance;
Δ  the shell side is a double-tube flow, with a longer flow path and higher flow velocity, resulting in better heat transfer performance;
Δ  high pressure resistance;
Δ  the tube bundle can be withdrawn from the shell for maintenance and cleaning, the structure is simple and inexpensive.

Applications:
suitable for situations where the temperature difference between the tube and shell walls is large, or where the shell-side medium is prone to scaling while the tube-side medium is clean and less prone to scaling, high temperature, high pressure, and strong corrosive conditions.


3. Floating head Tube Heat Exchanger
 
NOBLEST Floating head heat exchanger, only one end of the two ends of the tube plate is fixed with the shell, the other end can move freely relative to the shell, called the floating head. The floating head is composed of a floating tube plate, a hook ring and a floating head end cover. It is detachable and the tube bundle can be drawn from the shell. The thermal deformation of the tube bundle and the shell are not constrained, so there is no thermal stress.

Features:
The advantages are convenient cleaning between tubes and tubes, and no thermal stress will be generated; However, its structure is complex, the cost is higher than that of the fixed tubeplate heat exchanger, the equipment is bulky, the material consumption is large, and the small cover of the floating head can not be checked during operation, and the sealing requirements are higher during manufacturing. It is suitable for the occasions where the wall temperature difference between the shell and the tube bundle is large or the shell medium is easy to scale.

Applications:
Δ The tube bundle can be drawn out to facilitate cleaning of the tube and shell process;
Δ The temperature difference between the medium is not limited;
Δ It can work under high temperature and high pressure, the general temperature is less than or equal to 450 degrees, and the pressure is less than or equal to 6.4 mpa;
Δ Can be used for more serious scale occasions;
Δ Can be used for easy corrosion of pipe.
