Ceramic lined wear-resistant pipe are used for coal powder transportation in thermal power plants

Product Description

The ceramic lined wear-resistant pipe adopts a composite structure design of "alumina ceramic lining + metal outer layer": the inner layer is made of high-quality alumina ceramic (purity ≥92%), with a Mohs hardness of 9, and has super wear resistance; the outer layer is made of low-carbon steel or stainless steel to provide structural support and compressive resistance. Through a special process, the ceramic and metal are closely combined, which not only retains the high wear resistance of ceramics but also has the strength and toughness of metal pipes, and can adapt to the material transportation needs under different pressures and temperatures.

As a conveying equipment designed for high-wear conditions, the ceramic lined wear-resistant pipe has become an ideal choice for cement, steel, thermal power, ports, chemicals, mining, coal, smelting, engineering machinery and other industries with its excellent wear resistance, effectively solving the problem of pipeline loss in the transportation of various hard materials. ​

Core Features of the Product

Extreme wear resistance: The wear resistance of alumina ceramic lining is 10-20 times that of ordinary steel pipes and 5-8 times that of high-chromium cast iron pipes. It can withstand long-term erosion of hard materials with a particle size of ≤50mm and a flow rate of ≤30m/s.

Stable and reliable structure: The bonding strength between ceramic and metal is ≥20MPa, and it is not easy to fall off under working conditions such as vibration, impact, and temperature changes. The impact strength is above 12MPa.

Corrosion resistance range: It can operate stably in an environment of -50℃-300℃, and can withstand corrosive media such as acid, alkali, and salt spray. It is suitable for complex working conditions in multiple industries.

Smooth conveying design: The inner wall is smooth (roughness Ra≤0.8μm), the material flow resistance is small, the blockage phenomenon is reduced, and the conveying efficiency is improved by 15%-30%.​
Flexible customization of specifications: supports different pipe diameters from DN50 to DN1200mm, as well as straight pipes, elbows, tees, reducers and other structures, which can be customized according to equipment size and conveying path. ​
