The ceramic Lined Pipe and Fittings has overcome the low hardness and wear resistance of the steel pipe due to the high strength, good toughness, impact resistance, good welding performance of the steel pipe and the high hardness, high wear resistance, corrosion resistance, and heat resistance of the corundum porcelain. It has the characteristics of poor performance and poor ceramic toughness.
ceramic Lined Pipe and Fittings mainly include straight pipe, elbow, tee, reducer, etc. The lined ceramic process is divided into two types: ceramic patch and integral ceramic ring lining.
1. The wear-resistant lining ceramic is a patch process, and the alumina content is 95%, which is 10 times the service life of ordinary pipes. The equipment is dusted and polished, and the high-temperature and high-strength adhesive are used to paste and solidify the ceramic and equipment. The ceramic Lined Pipe and Fittings are widely used in electric power, metallurgy, mining, coal, chemical industry, lithium battery, construction machinery, port, and other industries.
2. The overall wear-resistant ceramic lined pipeline is made by using isostatic pressing technology to integrally fire the wear-resistant ceramic tube and pour it inside the steel pipe. Very strong. It is mainly suitable for material transportation of lithium battery materials, mineral powder, limestone, mineral processing, metallurgy, electric power, coal, and other industries.

Differential performance of ceramic lining bending tube and casting steel and cast steel
The fundamental reason for wear-resistant high-aluminum ceramic lining materials is the fundamental reason for excellent quality of the product itself, and the advantages of many aspects of the traditional material, such as cast stones, cast steel, and other materials.
1. Casting stones: The characteristics of wear-resistant cast stone elbow are fragile, cracking, and wear the noodle backpack, 25-35 mm wall thickness, and after a short time in the inside, the coal is worn outward with the gap and the service life is used to use the service life. It cannot be guaranteed that once it is worn, it cannot be repaired at the scene.
2. Casting steel: cast steel is widely used in the field of abrasion and anti-wear, and the manufacturing process is very simple. The surface hardness (about 60) of cast steel materials is much lower than ceramic (above 80), and the wear resistance is only one-tenth lower than the ceramics. In addition, cast steel pipelines are large, very bulky, and have high carbon content, and poor weldability. It is necessary to treat welded seams on the spot, which brings considerable difficulties to installation and maintenance.
