With the improvement of people's performance requirements for elbows, wear-resistant elbows have gradually gained popularity in the market and have replaced some traditional elbows. This is basically because the quality of wear-resistant elbows is good and they can adapt to some extreme environments. However, many people do not know how to distinguish wear-resistant elbows from traditional elbows when purchasing. Let's take a look together!
Performance comparison
1.Cast stone
In the past, most of the elbow pipes in each factory were made of cast stone elbows, which were characterized by brittleness and cracking, surface backpacking wear, and a wall thickness of25Millimeters and35Millimeters, approximately40millimeter. After a brief period of wear and cracking, it will wear out along with the gap and require a major overhaul, which will shorten its service life. There are often air holes inside, which can easily leave hidden dangers. Once an unexpected situation occurs, it will lead to irreparable results.
2.Cast steel
Cast steel (including alloy steel) is widely used in the field of wear resistance, and its manufacturing process is relatively simple. However, due to the limitations of the material's own properties and technology, the surface hardness of cast steel materials (approximately)60It is much lower than the surface hardness of ceramic materials (exceeding)80Its wear resistance is only one-tenth of that of ceramic materials. Therefore, wear-resistant elbows generally do not use this material.
3.Centrifugal casting of composite ceramic tubes
This process is formed through self-propagating centrifugal casting. It mainly utilizes the chemical reactions of substances themselves, exothermic combustion to generate high temperatures, and the technology of synthesizing new substances during the propagation of combustion waves.
Compared with carbon steel and manganese steel pipes, the wear resistance of ceramic composite pipes formed by this method has been improved to a certain extent. However, due to the low reaction temperature (the average temperature does not exceed.1200(Celsius), it is also aluminium oxide, but the strength, hardness and density of aluminium oxide in the high-temperature phase and the low-temperature phase are quite different. During the actual preparation process, due to the very short reaction time of the material, alumina and molten iron cannot be completely separated at low temperatures. This also leads to the ceramic layer not being dense enough. However, wear-resistant elbows are different. They use a very dense ceramic layer and have an outstanding actual anti-wear effect.
Furthermore, the centrifugal casting process of the composite ceramic pipe determines that it is not suitable for elbows and sizing heads. Under general technological conditions. Composite ceramic tubes can only be made into straight tubes. In order to shape the bent pipe or small pipe, the straight pipe must be divided into several welded sections. The inner walls of the formed elbow pipes and small round heads are not streamlined structures, which hinders the transportation of materials and reduces the output of the equipment.
So from the above content, it can be known that the cost performance of wear-resistant ceramic elbows is very high. When purchasing elbows, if the conditions are suitable, using wear-resistant elbows not only enhances the wear resistance of the elbows but also extends their service life.
