P91 reducer

P91 reducer has different functions and strengths by adding different components in actual production. Adopt certain production standards and methods, and have certain performance in use. The characteristic of eccentric P91 reducer is that its strength is significantly higher than that of carbon steel with the same carbon content, and it has good toughness, plasticity and weldability

For practical effect, the performance of the main steel. On the basis of carbon steel, other alloy elements are added, such as silicon, manganese, chromium, nickel, tungsten, vanadium, titanium, etc. This steel is called alloy steel. According to the different alloy elements added, eccentric P91 reducer has different properties, such as stable performance, mainly based on actual reports, low temperature resistance, high magnetism and other excellent special properties

The middle of P91 reducer is the main pipe section, and the two ends are eccentric straight pipe sections. There is an eccentric reducing transition section between the main pipe section and the eccentric straight pipe section. The bottom line of the eccentric P91 reducer remains straight; The preparation method of eccentric P91 reducer is to directly reduce the eccentric diameter on the metal pipe by using multiple sets of pressure equalizing dies. First, reserve the main pipe section in the middle of the entire metal pipe, and then press the die in with multiple sets of pressure equalizing dies according to the requirements of the reducing angle. The eccentric reducer processed by the method of the invention has no weld on the entire eccentric P91 reducer. As a special pipe in the corrosive liquid, the eccentric P91 reducer can extend the eccentric large and small heads, In particular, the service life of the underground eccentric water distributor shell, because there is no welding, will not occur corrosion and cracking at the welding joints, the production process is flexible, and the eccentric straight pipe section can be processed with eccentric reducers of any diameter and length. The size of the eccentric P91 reducer varies with different connecting pipes and industries

In electric power, mining, metallurgy and other industries, the transportation and export of materials are carried out by short distance and high voltage. The pipeline bears considerable pressure and is severely worn. Single material pipe is difficult to meet the requirements of this working condition, especially elbow, concentric head, stamping elbow and other pipe fittings. Considering its safety and service life, it is to improve the toughness and impact resistance of the pipe lining. At the same time, the overall strength of pipes and elbows shall also be considered
