In the actual production of eccentric reducer, different components are added according to different functions and strengths, and certain production standards and methods are adopted to add, which has certain performance in use. The characteristic of eccentric reducer is that its strength is obviously higher than that of carbon steel with the same carbon content. In order to improve the properties of steel, silicon, manganese, chromium, nickel, tungsten, vanadium, titanium and other alloy elements are added into carbon steel.
According to the different alloy elements, eccentric reducer has different performance, such as high wear resistance, corrosion resistance, low temperature resistance, high magnetism and so on. The main pipe section is in the middle of eccentric reducer and the eccentric straight pipe section is at both ends. There is an eccentric reducing transition section between the main pipe section and the eccentric straight pipe section, and the bottom line of the eccentric reducing pipe is kept straight; the preparation method of the eccentric reducing pipe is to use multiple sets of grading dies to shrink the diameter directly on the metal pipe, first reserve the main pipe section in the middle of the whole metal pipe, and then use multiple sets of grading dies to press the pipe step by step according to the requirements of the reducing angle, which can be used in corrosive liquid to prolong the eccentric length It is especially suitable for the shell of eccentric water distributor. Because there is no weld, there will be no corrosion and cracking at the weld. The production process is flexible, and the eccentric reducer with any diameter and length can be processed
Different sizes of eccentric big and small heads lead to different connecting pipes and different applicable industries. In electric power, mining, metallurgy and other industries, the transportation and export of materials are close and high-voltage. The pipeline bears considerable pressure and is seriously worn. It is difficult for single material pipe to meet the requirements of this condition, especially for elbow, concentric reducer, stamping elbow and other pipe fittings. In consideration of its safety and service life, the design is focused on improving the toughness, impact resistance and wear resistance of the pipeline lining. At the same time, the overall strength of pipes and elbows should also be considered.
