Which material conveying pipeline is more suitable? Ceramic pipes or metal pipes？
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 ceramic pipes and metal pipes, Which one is more suitable?
1. Anti-wear
First of all, from the perspective of wear resistance, the most important factor affecting wear resistance is the hardness of the material, and 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. If 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, and the anti-wear ability is very strong, and the price performance ratio is very high.
2. Anti-corrosion
Anti-corrosion mainly refers to acid-base corrosion. Metal materials are chemically active and easily react with acid-base to be corroded. The wear-resistant ceramics are calcined at a high temperature of 1650°C to convert alumina into α-alumina with very stable performance, which has excellent resistance to acid and alkali corrosion.
3. 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 of the pipeline and the firmness of the connection. The initial smoothness of metal pipes and ceramic pipes is relatively high, but the smoothness of metal pipes will decrease after wear, while wear-resistant ceramic pipes will become smoother as they are worn because of the addition of self-lubricating components. In terms of connection, metal pipes have a greater advantage, but the length of my ultra-long one-piece wear-resistant ceramic pipe can reach 3 meters, which greatly reduces the number of connection points and effectively makes up for this problem.
From these three points, in general 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 has been recognized by the market. highly recognition.
