Vertical Shell And Tube Heat Exchanger

Wuxi Hongdinghua Chemical Equipment Co., Ltd., as a professional manufacturer of Vertical Shell And Tube Heat Exchanger, has many years of cooperation with customers from the petroleum, chemical, pharmaceutical, environmental protection, and metallurgical industries. The heat exchanger is the most widely used equipment among the equipmenst supplied by Wuxi Hongdinghua Chemical Equipment Co., Ltd. Especially for shell and tube heat exchangers.

Shell and tube heat exchangers can be classified into many different names according to their internal structure, or according to the medium flow mode within the shell and tube heat exchanger, or their applications, such as condenser, cooler, heater, preheater, reboiler, cold trap, multi tube pass condenser, U-tube heat exchanger, floating head heat exchanger, packing box heat exchanger, etc., with numerous names.

Wuxi Hongdinghua Chemical Equipment Co., Ltd. categorizes so many shell and tube heat exchangers according to their installation positions using more intuitive and understandable terms:

Vertical shell and tube heat exchanger

Horizontal shell and tube heat exchanger

The basic structure of all these heat exchangers with different names is almost with the same or similar structure;

The structure of a shell and tube heat exchanger includes the following:

Shell and tube heat exchangers are mainly composed of bonnet(integral cover), tube sheet, tubes, shells, and baffle plates.

Usually, the shell is cylindrical; The pipes are straight or U-shaped. To improve the heat transfer efficiency of heat exchangers, threaded tubes, finned tubes, etc. can also be used. The pattern of tubes layout includes equilateral triangles, squares, corner squares, and corner triangle.

Characteristics and applications of Vertical Shell-Tube Heat Exchanger:

A vertical shell and tube heat exchanger consists of a shell and a tube bundle containing many tubes, and the heat exchange between cold and hot fluids is carried out through the tube walls. As a traditional standard heat exchange equipment, shell and tube heat exchangers are widely used in chemical industry, oil refining, petrochemical industry, power, nuclear energy and other industrial devices, especially in high-temperature and high-pressure and large-scale heat exchangers, which occupy absolute advantage.

Vertical Shell-Tube Heat Exchanger details:

Usually, the working pressure of vertical shell and tube heat exchangers can reach 4 MPa, and the working temperature is below 200 ℃. In some cases, higher pressure and temperature can also be achieved. Generally, the diameter of the shell is below 1800 millimeters, and the length of the tube is below 9 meters. In some cases, there are also larger or longer tubes.

The wall surface of the tube bundle enclosed in the shell serves as the heat transfer surface of the inter wall heat exchanger. Vertical shell and tube heat exchanger has a simple structure, low cost, wide flow cross-section, and is easy to clean scale; However, the heat transfer coefficient is low and the floor area is less than that of horizontal type shell and tube heat exchanger . It can be manufactured from various structural materials (mainly metal materials) and can be used at high temperatures and pressures, making it most widely used . Vertical Shell and tube heat exchangers include vertical fixed tube sheet steam water heat exchangers, vertical shell and tube steam water heat exchangers with expansion joint, and other types. The main control parameters of shell and tube heat exchangers are heating area, hot water flow rate, heat exchange capacity, and heat medium parameters.
