Structure and manufacturing standard of shell and tube heat exchanger
The shell and tube heat exchanger is to connect the tube to the tube sheet, and then fix it with the shell. Its types are roughly divided into fixed tube sheet type, kettle type floating head type, U-shaped tube type, sliding tube sheet type, stuffing box type and casing type.
According to the type of medium, pressure, temperature, dirt and other conditions, the various structural characteristics of the connection between the tube sheet and the shell, the shape and heat transfer conditions of the heat transfer tube, the cost, the convenience of maintenance and inspection, etc., the design and manufacture of each A shell and tube heat exchanger.
Shell and tube heat exchanger structure and manufacturing standards Generally speaking, shell and tube heat exchangers are easy to manufacture, low in production cost, wide in material selection, easy to clean, strong in adaptability, large in processing capacity, reliable in operation, and can adapt to high temperature and high pressure. . Although it cannot compare with plate and plate-fin heat exchangers in terms of compact structure, light heat transfer and unit metal consumption, it is widely used in chemical, petroleum, energy and other industries due to some of the aforementioned advantages. still in a dominant position.
Shell and tube heat exchanger structure and manufacturing standards
Shell-and-tube heat exchanger: a wall-type heat exchanger that uses the wall of the tube bundle enclosed in the shell as the heat transfer surface. This type of heat exchanger has a relatively simple structure and reliable operation. Various structural materials (mainly metal materials) can be used. ) manufacturing, can be used under high temperature and high pressure, is currently the most widely used type. (Design and manufacture follow the standard: TEMA ASME)
