Metal pipes and ceramic pipes are two kinds of pipes that are more common in industrial production today. In addition to bearing the burden of material transportation, they also shoulder many responsibilities such as wear resistance, corrosion resistance, and safety protection. Then when ceramic pipes meet metal which one would you choose?
Anti-wear: From the perspective of anti-wear, the most critical factor affecting wear resistance is the hardness of the material. Both metal and wear-resistant ceramics can increase the hardness by changing the formula and improving the process. However, the hardness and weldability of metal pipes conflict and restrict each other. When the hardness increases, the weldability will decrease significantly. If both are to be considered, the cost will rise linearly. In comparison, the hardness of ceramic pipes can reach HRA90 within the ordinary price range, the anti-wear ability is very strong, and the price-performance ratio is very high.
Anti-corrosion: Anti-corrosion mainly refers to acid-base corrosion. Metal materials have active chemical properties and are easily corroded by acid-base reactions. Wear-resistant ceramics are calcined at a high temperature of 1700°C to convert alumina into α-alumina with very stable performance, which has excellent resistance to acid and alkali corrosion.
Safety performance: The so-called safety performance refers to the stability of the pipeline during use, that is, whether there will be problems such as material hanging or material leakage during material transportation, which mainly depends on the smoothness and connection of the pipeline. Firmness. The initial smoothness of metal pipes and ceramic pipes is relatively high, but the smoothness of metal pipes will decrease after wear, and wear-resistant ceramic pipes will become smoother as they are worn because of the addition of self-lubricating components.
From the above three points, in general, in industrial applications, the performance of wear-resistant ceramic pipes with the same cost performance has obvious advantages, and in the emerging industry of lithium batteries, ceramic pipes can also isolate metal pollution, which the market has recognized—highly recognized.
