In metallurgy, chemical, pharmaceutical, mining and other industries, wear-resistant pipes are widely used, and wear-resistant pipes or wear-resistant elbows are used in processes such as dust removal, powder feeding, and flue gas desulfurization. So, what are the characteristics of wear-resistant pipes that make them used in many fields?
1. Has good heat resistance
Compared with common crowns made of metal, concrete, pvc, etc., wear{{0}}resistant pipes have very good heat resistance and thermal expansion coefficient. It has been scientifically proved that the wear-resistant pipes on the market can operate stably and normally for a long time in the temperature range of minus 50 degrees to minus 70 degrees, and the coefficient of thermal expansion can reach 6-810-6/0C, which shows that its good performance. Heat resistance.
2. It has the characteristics of anti-corrosion and anti-scaling
The porcelain layer of the wear{{0}}resistant pipeline has good neutral characteristics, and its corrosion resistance is outstanding, which effectively prevents the corrosion of the pipeline by the chemical waste liquid. At the same time, the inner surface has good gloss, and the cleaning resistance coefficient is less than 0.02, so the substances in the tube can pass through unhindered, and its scale inhibition performance is more prominent.
3. High hardness
At present, the lining layer of many wear{{0}}resistant pipes is made of corundum material, and its hardness reaches 9.0, and the wear resistance performance is outstanding. life.
4. Good welding characteristics
The wear-resistant pipeline itself is light in weight and has good welding characteristics. It can be connected by different processes such as flange, rapid connection, and electric welding, which greatly shortens the construction time and reduces the installation cost.
Therefore, it is precisely because of these high-quality characteristics of wear-resistant pipes that they are widely used in chemical, pharmaceutical, mining, urban construction and other fields.
