In actual production, eccentric reducers are added with different elements for different functions and strengths, using certain production standards and methods for addition, and have certain performance in their use The characteristic of eccentric reducer is that its strength is significantly higher than that of carbon steel with the same carbon content, it has good toughness and plasticity, as well as good weldability and corrosion resistance In order to improve and enhance the performance of steel, other alloying elements such as silicon, manganese, chromium, nickel, tungsten, vanadium, titanium, etc. are added to carbon steel. This type of steel is called alloy steel
The eccentric head has different properties depending on the added alloy elements, such as high wear resistance, corrosion resistance, low temperature resistance, high magnetism, and other excellent special properties The middle of the eccentric reducer is the main pipe section, and the two ends are eccentric straight pipe sections. There is an eccentric diameter reduction transition section between the main pipe section and the eccentric straight pipe section, and the bottom line of the eccentric reducer remains straight and unchanged; The preparation method of eccentric large and small heads is to use multiple sets of grading molds to directly reduce the eccentric diameter on the metal tube. First, leave a main pipe section in the middle of the entire metal tube, and then use multiple sets of grading molds to press it step by step according to the requirements of the variable diameter angle The eccentric head processed by the method of the present invention has no weld seam on the entire eccentric head; Eccentric reducers are used as specialized pipes in highly corrosive liquids, which can extend the service life of eccentric reducers. Especially when used as the casing of underground eccentric water distributors, they will not corrode or crack at the weld joint due to the lack of welding seams; The production process is flexible and can process eccentric large and small heads of any diameter and length of eccentric straight pipe sections
The size of the eccentric head and the size of the connected pipe are different, and they are also suitable for different industries. In industries such as power, mining, and metallurgy, material transportation and output are carried out using close range and high-pressure transportation. Pipelines are subjected to considerable pressure and severe wear, and single material pipelines are difficult to meet the requirements of this working condition, especially for fittings such as elbows, concentric heads, and stamped elbows. Considering their safety and service life, the focus is on improving the toughness, impact resistance, and wear resistance of the pipeline lining. At the same time, the overall strength of pipelines and elbows should also be considered.
Before bonding the eccentric head, use a dry cloth to wipe the socket side and the outer side of the socket. If there is oil stains on the surface, use acetone to wipe it clean. The following points should be noted:
1. Control caliber: DIN standard, 3A/IDF standard, ISO standard;
2. International industrial standards: DIN, ISO, SMS, 3A, IDF, etc;
3. Product materials: stainless steel 304, 316, 316L;
