Product content
The lining ceramic layer of the alumina ceramic lining pipe is engineering ceramics, and its hardness (HRA) is ≥84, and its performance is more than 10 times that of high-chromium cast iron alloy pipe fittings. With a 5mm thick ceramic layer, its actual service life will be equivalent to 50mm thick cast steel. Choose different ceramic materials, have anti-corrosion performance against different corrosive media, and resist acid, alkali, salt and other strong corrosive media and halogen salt corrosion characteristics.

Note:
①The pipeline of the mine's gravity separation workshop, the ore size is less than 2mm, and the weight concentration is 30%
②Ceramic steel pipe outer diameter φ245, thickness 8mm, ceramic layer thickness 4mm, 20# carbon steel pipe thickness 9mm
③This comparative test is still ongoing, and the ratio of 175 is only based on the estimated data of three years of practice
The ceramic steel straight pipes and ceramic steel elbows, reducers, tees, crosses, multi-way pipes, etc. produced by our factory have been used in more than 200 coal-fired power plants, more than 50 mines, as well as coal, building materials, Industries such as machinery and petroleum have been applied. For example, in the case of severe wear, the ceramic steel straight pipe has been used for several years, and until now, no ceramic steel straight pipe has been worn through. The service life of the fastest-wearing ceramic steel elbow is ten times longer than that of cast stone elbows and wear-resistant alloy steel elbows, and fifteen times longer than steel-plastic and steel-rubber elbows.
