The tube bundles of the tube heat exchanger are connected to the tube sheets. The tube sheets are welded to both ends of the shell and connected to the top cover. The top cover and the shell are provided with fluid inlet and outlet nozzles. A series of baffles are usually installed outside the tubes perpendicular to the tube bundle. At the same time, the connection between the tube, the tube sheet and the shell is rigid, and there are two fluids with different temperatures inside and outside the tube. Therefore, when the temperature difference between the tube wall and the shell wall is large, due to their different thermal expansion, a large temperature difference stress will be generated, causing the tube to bend or the tube to loosen from the tube plate, or even damage the heat exchanger.
As we all know,Tube and tube heat exchangerIn the heat exchange industry, it not only has many advantages, but also has good oxidation resistance of stainless steel, which is safe and hygienic. It can be used in fields such as food, heating, domestic hot water and waste heat recovery. It not only has high heat exchange efficiency, but is also strong and durable. Today we will introduce what issues you need to pay attention to when placing it.
1. Do not mix the heat exchanger with carbon steel when placing it, because carbon steel will cause pollution to the heat exchange equipment.
2. The heat exchanger package cannot be placed under the truss car or other equipment that may drip oil or grease.
3, Try to use it indoors. If it is necessary to use it outdoors, be sure to have a cover to cover it.
4, The supporting equipment of the tube and tube heat exchanger should be kept away from the working area where plasma cutting, grinding or painting is carried out.
