Characteristics of carbon steel eccentric reducer
Carbon steel eccentric reducer is a type of pipe fitting that is applied to the reduced diameter of the pipe. Carbon steel eccentric reducer refers to the size of the center (reducer) that is not in the same line. Its role is to put a wall or stick to the pipeline without occupying space, and it is to connect two pipes of different diameters and change the size of the flow.
Production Process of carbon steel eccentric reducer
The commonly used forming processes are reduce-diameter and expand-diameter press forming process. For some sizes of different diameters, punching can also be used.
In the reduce-diameter press forming process, the tube blank having the same outer diameter as the large diameter end of the different diameter tube is put into the forming die, and the blank is moved along the direction of the axis of the blank to make the blank move along the cavity of the mold and shrink and form, according to the different diameter tube bend. The size of the path is divided into one press forming and multiple press forming.
The expand-diameter pressing is the use of blanks that are smaller than the outer diameter of the large diameter end of the different-diameter pipe, and the inner die is used to expand the neck along the inner diameter of the blank. The method of expanding the neck mainly solves the problem that the reduction-diameter-reducing different-diameter pipe is not easy to be processed through necking, and sometimes the neck-up and neck-down are used in combination according to the processing requirements of the material and the product.
Key points of production of carbon steel eccentric reducer
In the reduce-diameter and expand-diameter press forming process, according to different materials and changing conditions, it is determined to use hot or cold pressing. Under normal circumstances, materials that are cold pressed but are cold pressed to cause severe work hardening and thick-walled products or alloy steels as much as possible should be formed by hot pressing; the surface quality of different-diameter tube raw materials also affects the difference. The quality of the tube. For example, the more serious rust spots will make the surface quality of the reducer worse, the surface cracks will deepen in the deformation process, the surface of the sandwich will cause the reducer to be scrapped, the surface of the mechanical scar will make the reducer in the formation of cracking, the spiral of the pipe Corrugation will make the reducer corrugated and so on.
Therefore, before the formation of the carbon steel eccentric reducer, the surface of the raw material should be inspected and the surface defects should be cleaned. Inherent quality of raw materials is usually not clearly shown, such as internal cracks, slag inclusions, porosity, porosity and other defects, to be detected by such methods as non-destructive testing, or exposed during the formation process. Therefore, the raw materials for manufacturing different diameter pipes should generally pass through such as hydrostatic pressure test, eddy current inspection, and ultrasonic testing. In the case of high-pressure reducers or reducers for special requirements of the process, manufacturers usually perform ultrasonic testing or other additional tests on raw materials or formed products, such as metallographic examinations, to ensure that the internal quality of the material meets the requirements.
