  Types of Shell and tube heat exchanger Shell and tube heat exchanger  is also called tubular heat exchanger. It is a partition type heat exchanger with the wall surface of the tube bundle enclosed in the shell as the heat transfer surface. Shell and tube heat exchanger has simple structure, low cost, wide circulation cross section, and easy to clean scale; but it has low heat transfer coefficient and large area. It can be made of various structural materials (mainly metal materials) and can be used under high temperature and high pressure. It is the most widely used type. Shell and tube heat exchangers include fixed tube plate steam-water heat exchangers, shell and tube steam-water heat exchangers with expansion joints, floating head steam-water heat exchangers, U-shaped shell and tube steam-water heat exchangers. Corrugated shell and tube steam-water heat exchanger, segmented water-water heat exchanger and other types. The main control parameters of the shell and tube heat ...

  What is a spiral plate heat exchanger? In simple terms, it is one of the common types of heat exchangers. It is a type of heat exchanger that is made of two spiral passages made of metal plates and exchanges heat between hot and cold fluids. Its advantages are compact structure, small size, and high heat transfer efficiency. Its application is mainly in industries that require heat conversion, such as petroleum, chemical, pharmaceutical, machinery, electric power, and environmental protection. 1. Specific types of spiral plate heat exchangers. Spiral plate heat exchangers are generally divided into two types: detachable and non-detachable. Among them, the non-detachable structure is relatively simple, that is, both ends of the spiral channel are all welded, so that it is not removable. The detachable spiral plate heat exchanger is different in structure from the non-detachable type, mainly in that the two ends of the spiral channel are sealed structures instead of welded. As for ...

Heat exchanger market Heat exchangers are one of the most important and widely used process equipment required by modern industry. Regardless of the industry involved, it may require some type of temperature regulation, at which point the heat exchanger may play its role. According to forecasts, by 2021, the heat exchanger market will be worth 20 billion US dollars. This is a huge market, especially in the Asia-Pacific region, especially in the chemical, oil and gas, food and plastic manufacturing industries. Demand is growing rapidly. How does a heat exchanger work Heat exchangers can be used for heating or cooling. In the industrial field, especially in large factories and some refineries, heat exchangers are mostly used for cooling. Usually used with heat transfer fluids (HTF)-basic products, intermediate products, and final products. Many industrial processes require a certain amount of heat to function. However, great care must be taken to prevent these processes from becom...

Heat exchangers are widely used in many industries and in this article we mainly introduce three types heat exchanger: brazed heat exchanger, tubular heat exchanger and plate heat exchanger, analyse their structure, advantage and disadvantage. www.murphyfinnedtubes.com Tub ular   (also known as shell and tube or tube)  heat exchanger  is the most typical interwall heat exchanger, its application in industry has a long history, and is still in the dominant position of all heat exchangers. It can effectively reduce heat loss and improve energy utilization efficiency. The tubular heat exchanger is mainly composed of shell, tube bundle, tube plate and sealing head. The shell is mostly round, with parallel tube bundles inside, and both ends of the tube bundle are fixed on the tube plate. It mainly diverse into three types: Fixed tube-plate heat exchanger : simple structure, low cost, easy to manufacture, easy to clean and repair the pipe, but dif...

Fixed tube plate type: fix both ends of the pipe on the fixed tube plate at both ends of the shell. The tube plate is fixed to the shell. Advantages: simple structure, low manufacturing cost, wide range of specifications, widely used in engineering. Disadvantages: shell side inconvenience cleaning, can only use chemical cleaning, maintenance is difficult, more dirty or corrosive media can not go through the shell. When the temperature difference between the shell and the heat exchanger is large,small temperature difference stress can be reduced by single or multi-wave expansion. U-tube type: the heat exchange tube is bent into a u-shape, and the two ends of the tube are fixed in the same block. On the tube plate, the bending end is not fixed. Heat exchange tube can be freely telescopic, so the shell and heat exchange tube without thermal stress. There is only one tube plate, the structure is simple, the tube bundle can be taken out from the shell, the shell side is easy to clean,...
