As an important link in pipeline transportation, elbows are the hardest hit area of wear in
pipelines. In order to enhance the wear resistance of elbows, many manufacturers line elbows with wear-resistant ceramics as a wear-resistant layer, which is a wear-resistant ceramic elbow. There is an important parameter in wear-resistant ceramic elbows, that is R, so what does R represent in wear-resistant ceramic elbows? How can we judge the quality of ceramic elbows?
In wear-resistant ceramic elbows, R represents the bending radius. The larger the R, the larger the bending radius, and the more relaxed the elbow turns. The smaller the R, the smaller the bending radius, the more rapid the elbow turns, the more concentrated the impact force and wear are, and it is easy to wear through or impact damage. Therefore, the smaller the R, the more attention should be paid to wear prevention, and thicker and better wear-resistant ceramics should be selected.
The quality judgment of wear-resistant ceramic elbows mainly depends on three aspects:
1. Hardness of wear-resistant layer: The hardness of the wear-resistant layer is also the hardness of the lining ceramic, which is an important indicator for determining the wear resistance of the elbow, and the hardness of the lining ceramic is determined by many factors such as powder quality, sintering temperature, and production process. Chemshun Ceramics has been focusing on the research and development and production of wear-resistant ceramics for 30 years. It insists on using high-quality Australian powder, has excellent equipment and mature production technology, and also has a variety of kilns such as atmospheric kilns, electric kilns, and hanging kilns, which can accurately control the sintering temperature. The hardness and quality of Chemshun wear-resistant ceramics have been unanimously recognized by new and old customers at home and abroad.
2. Surface smoothness: The surface smoothness of the lining ceramic also has a great influence on the wear resistance of the elbow, and will also affect the smoothness of the pipeline. The ceramic smoothness is also determined by factors such as powder and sintering process. The lining ceramic of the elbow of Chemshun Ceramics has been polished and processed through multiple processes, and the surface is smooth. While preventing wear, it also reduces hanging materials and blockages.
3. Ceramic thickness: Ceramic thickness is the main factor that determines the wear resistance and service life of the elbow. However, considering the internal space and material flow of the pipeline, the thicker the ceramic, the better. For this situation, Pingxiang Chemshun Ceramics has developed a backpack elbow. A ceramic backpack is installed in the part of the elbow that is more worn to increase the thickness of the ceramic, so that wear resistance, cost and the pipeline itself can be taken into account.
