Wear-resistant ceramic lined elbows VS ordinary pipe elbows?

The wear of elbow fittings has always affected the safe and civilized production of industrial and mining enterprises. With the development of science and technology, the innovation of materials, and the emergence of wear-resistant materials, materials such as cast steel elbows, alloy steels, self-igniting composite ceramics, wear-resistant ceramic patches (or ceramic bushings) emerge in an endless stream, but each has its own advantages. shortcoming. Among them, the wear-resistant ceramic elbow is a kind of wear-resistant and cost-effective pipe fittings.

First, literally:
The difference between wear-resistant ceramic lined elbows and ordinary elbows is literally: one is a pipe fitting lined with wear-resistant ceramics, and the other is an ordinary steel elbow.

Second, the materials themselves are different:
Alumina wear-resistant ceramics have become one of the most widely used wear-resistant materials due to their high hardness, high wear resistance, impact resistance, oxidation resistance, corrosion resistance, and high and low temperature resistance. As determined by the Institute of Powder Metallurgy of Central South University, the wear resistance of wear-resistant ceramics is 266 times that of manganese steel and 171.5 times that of high-chromium cast iron. Compared with ordinary elbows, the wear resistance is better. Then there is the high hardness of wear-resistant ceramics. According to the data of the Shanghai Institute of Ceramics, Chinese Academy of Sciences, the Rockwell hardness of corundum ceramics is above HRA85, which is much higher than that of wear-resistant steel. Ceramic is half as dense as steel.

Finally, the advantages of wear-resistant ceramic elbows:
Both materials described in this article have the same caliber and wall thickness.

  1. The wear-resistant ceramic elbow is half lighter than the ordinary elbow.
  2. The service life of wear-resistant ceramic elbows is 10 times that of ordinary elbows.
  3. The elbow lined with wear-resistant ceramics, the more polished, the smoother it is, the running resistance is small, it is not formed, and the pipe is not blocked.
  4. Reduce energy waste, reduce replacement frequency, and improve enterprise production capacity.
  5. Reduce the “running drip” of the pipeline and improve environmental protection and safety.
