Fixed tube plate heat exchanger In the fixed tube plate heat exchanger, fluids of different temperatures flow through the tube side and shell side, and heat exchange is completed through heat exchange. When the temperature difference between the two fluids is large, in order to avoid higher temperature difference stress, a compensation ring (expansion joint) is usually added at an appropriate position on the shell side. When the thermal expansion of the shell and the tube bundle is different, the compensation ring undergoes slow elastic deformation to compensate for the thermal expansion caused by temperature difference stress. Composition and characteristics of fixed tube plate heat exchanger Composition of fixed tube plate heat exchanger  The fixed tube plate heat exchanger is composed of tube boxes, shells, tube sheets, tubes and other components. It has a compact structure, many rows of tubes, a large area under the same diameter, and is relatively simple to manufacture. The struct

Floating head heat exchanger One end of the tube sheets at both ends of the floating head heat exchanger is not connected to the shell, and this end is called a floating head. When the tube is heated, the tube bundle together with the floating head can freely expand and contract along the axial direction, completely eliminating the temperature difference stress. Floating head heat exchanger structure Drill holes and wire or weld multiple screws evenly between the concave and trapezoidal grooves. Set the floating head flange as a double seal of convex and trapezoidal bosses. The dividing plate is connected to the trapezoidal bosses and located at A wide-face flange with the same end face, and the convex and trapezoidal bosses and split-range partitions match the concave and trapezoidal grooves and split-range grooves of the floating head tubesheet respectively. The floating head flange is matched with the spherical surface without flanging The head is assembled and welded into a floatin

Floating coil heat exchanger Floating coil radiators can be widely used in boilers in heating, air conditioning and hot water supply systems in industrial and civil buildings such as chemical, oil refining, shipbuilding and other factories as well as hotels, restaurants, office buildings, school scientific research buildings, Yiyuan outpatient wards and other buildings. It is used as heat exchange equipment in rooms, heat exchange station buildings and air-conditioning machine rooms. Floating coil heat exchanger  application scope 1. The heat exchanger shell has two types: ordinary steel plate and stainless steel plate, and the heat transfer tube bundles are all copper tubes. 2. The tube side design pressure of the heat exchanger is 0.1-0.9MPa for steam type and ≤1.6MPa for water-water type; the shell is equipped with three specifications of 0.6MPa, 1.0MPa and 1.6MPa respectively. When selecting equipment, pay attention to the heat source and equipment. performance to match. 3. Due to

Shell and tube heat exchanger Shell and tube heat exchanger is also called tube and tube heat exchanger. It is a partition type heat exchanger that uses the wall surface of the tube bundle enclosed in the shell as the heat transfer surface. This kind of heat exchanger has a simple structure, low cost, wide circulation section, and easy cleaning of scale; but it has a low heat transfer coefficient and a 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. The U-shaped tube heat exchanger is different from the fixed tube plate type and the floating head type. It has only one tube plate. The heat exchange tube is made into a U shape and both ends are fixed on the same tube plate. The tube plate and the shell are fixed by bolts. Together. Characteristics of U-shaped tube heat exchanger This kind of heat exchanger has a simple structure and low cost. The tube bundle can
