Should be prepared to what kind of equipment and materials and tools and equipment?
The type of tube plate heat exchanger and work Plate heat exchanger can be divided, according to the corrugated heat exchanger plate can be divided into according to washer and management unit, wave can be divided into one word, direct wave, spherical wave, in the form of bond type. The combination of various forms, in order to meet the needs of different working conditions, the use of more targeted. The herringbone corrugated plate as the same piece is sealed with adhesive type or management unit may be different, the use of management unit gasket glue may contain chlorine ion, can effectively prevent the corrosion of plates, and more convenient disassembly of the equipment. Another example is the temperature and pressure welding plate heat exchanger is significantly better than the removable plate heat exchanger, can reach 250 ℃, 2. Mpa. The same plate heat exchanger, the diversity of the form, can be applied to a wide range of areas, and can be used in most of the heat exchange process.
Tube plate heat exchanger products reached a mature stage, and to its high efficiency, energy saving and environmental protection advantages in feel frequently used in the field of various industries, is used to replace the original, tube and shell heat exchanger and achieved good results. The structure of the heat exchanger Tube and shell heat exchanger, also known as tube heat exchanger, heat exchange equipment, is a common standard, it has simple structure, strong and durable, low cost, wide range of wood easy to clean, the advantages of strong adaptability, the most widely used.
The role of the tube plate is heating tube bundle and the tube side and shell side fluid separation. You can keep the swelling down Tube plate and pipe connection or welding. Inflation connection is the use of expansion tube bulge, a significant plastic deformation, to achieve the purpose of sealing fastening between tube and tube plate according to the pressure. Expanding joint method is usually used segment of the carbon steel pipe carbon steel or low alloy steel, the design of less than 4 million mpa pressure, design temperature does not exceed 350 °. It is shell (3) of the head and tube box Head and tube box located at both ends, it is the function of control and distribution of tube side fluid.
