In many thermal power plants, coal ash conveying systems face severe pipeline wear due to the continuous transport of abrasive materials. Traditional rubber hoses or steel pipes often suffer from rapid wear, frequent maintenance, and costly downtime.
To address this challenge, Hunan Yibeinuo New Material Co., Ltd. has developed a high-performance ceramic-lined rubber hose designed specifically for abrasive material transport.
The product combines the flexibility of rubber with the extreme wear resistance of alumina ceramics. High-purity alumina ceramic tiles with a content of ≥95% are embedded inside the hose through an advanced vulcanization process. These ceramics feature a dense hexagonal structure that significantly improves wear resistance.

Compared with conventional rubber hoses, ceramic-lined rubber hoses offer 3 to 10 times longer service life, depending on the type of material being conveyed.
Another major advantage is flexibility. The hose structure allows large-angle bending without damaging the ceramic lining. This makes it particularly suitable for complex pipeline layouts in industrial plants.
The outer layer of the hose is made of high-toughness nitrile rubber, reinforced with polyester fabric and high elasticity steel wire to ensure reliable performance under different pressure conditions.
In addition, the smooth ceramic surface reduces flow resistance and prevents turbulence inside the pipeline, improving overall conveying efficiency.
Ceramic-lined rubber hoses are widely used in industries such as:
Thermal power plants
Cement plants
Mining concentrators
Steel mills
Port dredging projects
By significantly reducing pipeline wear and maintenance frequency, this technology helps companies lower operating costs and improve production efficiency.
As industries continue to demand more durable material conveying solutions, ceramic-lined rubber hoses are becoming an increasingly popular choice for high-wear applications.
