We produce tube heat exchangers in stainless steel, carbon steel, different sizes, tube and plate, floating head, U-tube types, according to ISO, ASME standards, to provide customers with low cost, high quality service.
Shell and tube heat exchanger consists of shell, heat transfer tube bundle, tube plate, folding plate (baffle) and tube box and other components. The shell is mostly cylindrical, with tube bundles inside, and the ends of the tube bundles are fixed on the tube plate. Heat transfer of cold and hot two kinds of fluids, one in the tube flow, known as the tube course fluid; the other in the tube outside the flow, known as the shell course fluid. In order to improve the heat transfer coefficient of the fluid outside the tube, usually installed in the shell of a number of baffles. Baffle can increase the shell fluid velocity, forcing the fluid to travel several times according to the specified lateral through the tube bundle, enhance the degree of fluid turbulence.

10, wide range of applications, can be widely used in thermoelectricity, factories and mines, petrochemical industry, urban centralized heat supply, food and medicine, energy and electronics, machinery and light industry and other fields.
11、The heat transfer tube adopts copper tube with rolled fins on the outer surface, which has high thermal conductivity and large heat transfer area.
12, the guide plate to guide the shell fluid in the heat exchanger is a folded continuous flow, the guide plate spacing can be adjusted according to the optimal flow rate, the structure is robust, to meet the large flow or even large flow, pulsation frequency of the shell fluid heat transfer.
13、When the shell process fluid is oil, it is suitable for low viscosity and cleaner oil heat exchange.
Shell and tube heat exchanger has a wide range of applications in chemical, petroleum, pharmaceutical, food, metallurgy, electric power and other industries. It can be used for heating, cooling, condensation, evaporation and other processes, is to realize the heat transfer and energy conversion of the important heat transfer equipment.
The fixed tube sheet heat exchanger is one of the most widely used configurations, using two end tube sheets with a shell. It is used when saving energy for good heat transfer in most applications from petroleum and chemical processing.
Advantages:
A floating head heat exchanger is constructed by one tube sheet which can be moved freely inside the shell to account for thermal expansion. This flexibility makes it suitable for operations where temperatures differ by large variances and conditions may become fouling.
Advantages:
The U-tube heat exchanger makes use of U-shaped tubes, so that their thermal expansion and contraction capabilities do not need a floating head. It is basically intended for cooling high-temperature fluids.

Shell and tube heat exchangers are a bundle of tubes enclosed by a shell. One fluid flows through the tubes while another fluid flows around them. This is achieved to efficiently transfer heat. By this arrangement, industries are able to control the temperatures in their processes. It is utilized in the generation of energy up to the processing of food. Shell and tube heat exchangers are essential parts of most industrial systems.
By its very name, it indicates that the stationary heat exchanger elements-the tubes themselves-are covered by a shell. The basic purpose is to transfer heat from one fluid to another, or vice versa by either heating or cooling the second fluid
Shell and tube heat exchangers are commonly used in chemical processing, petroleum refining, pharmaceutical production, food manufacture, and electric power generation.
Yes, they are made with maximum heat transfer, and very minimal energy would be consumed, and this will save on costs.
Shell and tube heat exchangers must undergo checks and cleaning, which would be done often based on the fluids used and the conditions of operation to ensure optimal performance.
