China Hunan Yibeinuo New Material Co., Ltd. Company News

In recent years, industries such as cement, mining, steel, and power generation have been facing increasing challenges related to equipment wear. High-speed material conveying and abrasive bulk materials significantly shorten the service life of traditional steel pipelines and components. As a result, more companies are turning to alumina ceramic wear-resistant solutions to improve reliability and reduce operational costs. Alumina ceramic materials are known for their high hardness, excellent wear resistance, and strong corrosion resistance. When applied as linings in pipes, elbows, and chutes, ceramic components can effectively withstand continuous abrasion from powders and granular materials. Compared with conventional steel components, the service life can be extended several times. In addition to durability, ceramic lining solutions also help reduce maintenance frequency and minimize production downtime. This is particularly important for large-scale industrial plants where shutdowns can lead to significant economic losses. With the increasing demand for efficiency and cost control, wear-resistant ceramic products are becoming an essential choice for bulk material handling systems. Their application is expected to continue expanding across various heavy industries.

In the demanding environment of a thermal power plant, the pneumatic conveying system for pulverized coal is a critical operation. However, the constant battle against severe abrasion, particularly at pipeline elbows where high-velocity coal particles impact the outer wall, has long been a source of costly maintenance and unplanned downtime for operators in the US and around the world. Yibeinuo New Materials understands this challenge intimately and provides a proven, engineered solution: our ultra-hard, wear-resistant ceramic-lined elbows. A leading thermal power plant in the Midwestern United States was facing exactly this issue. Their existing steel elbows were wearing through in a matter of months, leading to frequent shutdowns for replacement, high material costs, and safety concerns. Seeking a long-term, cost-effective solution, they turned to Yibeinuo New Materials. Our proposed solution was a custom-engineered wear-resistant ceramic sleeve, leveraging the superior properties of 95% alumina ceramic. The key to the solution’s success lies in its robust design and material specifications. Our ceramic ring-lined pipe features a three-layer structure. The outer shell is crafted from robust 304 stainless steel, providing structural integrity. A high-strength epoxy resin adhesive bonds the steel shell to a dense, 95% alumina ceramic inner lining. This lining, with a Rockwell hardness of ≥ HRA 85 and compressive strength of ≥ 1200 MPa, acts as an impenetrable shield against the abrasive coal particles. Furthermore, the ceramic liner is available in thicknesses from 5 to 15mm, allowing us to tailor the product to the specific severity of the plant’s operating conditions, which can handle temperatures up to 150°C. The results have been transformative. Since installing Yibeinuo’s Ceramic composite pipe, the plant has reported a service life of over five times that of their previous steel pipes. The ultra-smooth inner surface of the alumina ceramic (Al₂O₃ content ≥ 95%) ensures unimpeded material flow, eliminating the risk of hanging and blocking that was previously a problem. More importantly, the dramatic reduction in wear has led to a proportional decrease in maintenance frequency, saving the plant significant labor costs and preventing costly unscheduled downtime. By choosing Yibeinuo New Materials, the US power plant not only solved its immediate abrasion problem but also achieved a lower total cost of ownership. Our expertise in designing and manufacturing wear-resistant solutions—from our own factory with 15 years of industry experience—ensures that every product we deliver, including our ceramic-lined elbows, meets the highest standards of quality and performance, providing peace of mind and operational efficiency for our global clients.

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. Key technical specifications Parameter Specification Alumina Content ≥95% Density ≥3.6 g/cm³ Rockwell Hardness ≥85 HRA Compressive Strength ≥850 MPa Bending Strength ≥290 MPa Working Pressure 1–2.5 MPa Operating Temperature ≤100°C 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.

Conveyor transfer points are among the most vulnerable areas in bulk material handling systems. In industries such as mining, cement production, and coal-fired power plants, these transfer points experience continuous impact and sliding abrasion from heavy materials. Traditional steel liners often fail quickly under such harsh conditions, leading to frequent maintenance and costly downtime. Ceramic rubber composite liners offer an advanced wear protection solution for these demanding environments. By combining wear-resistant ceramic tiles with impact-absorbing rubber and structural steel backing, these liners provide both durability and flexibility. The ceramic tiles are sintered at high temperatures to create a dense microstructure with exceptional hardness. This allows the liner to resist abrasion from coal, ore, and other bulk materials. Meanwhile, the rubber layer plays a critical role in absorbing impact energy and protecting the ceramic components from sudden shock loads. Typical applications include: Conveyor transfer chutes Material impact zones Hoppers and bins Coal crushers With their long service life and easy installation, ceramic rubber liners are becoming a preferred wear protection solution in modern bulk material handling systems.

In bulk material handling industries such as thermal power plants and coal mining operations, hopper abrasion is one of the most common maintenance challenges. Large quantities of coal continuously impact the hopper walls, causing severe wear and frequent liner replacement. This problem not only increases maintenance costs but also leads to unexpected equipment downtime. To address these issues, many power plants are adopting ceramic rubber composite liners as an effective wear protection solution. These liners combine high-alumina ceramic tiles, elastic rubber layers, and steel backing plates through an integral vulcanization process, creating a durable and impact-resistant structure. The ceramic layer is made from 95% alumina material, which provides extremely high hardness and excellent wear resistance. Compared with traditional steel liners, ceramic liners can significantly extend the service life of equipment operating in abrasive environments. The rubber layer serves as an energy-absorbing buffer. When coal particles strike the liner surface, the rubber absorbs the impact force and reduces stress on the ceramic layer. This prevents cracking and ensures stable long-term operation. Typical specifications of ceramic rubber composite liners include: Parameter Specification Ceramic Material 95% Alumina Ceramic Thickness 10 mm Rubber Thickness 7 mm Steel Plate Thickness 6 mm Total Thickness 23 mm These liners are widely installed in coal transfer chutes, hoppers, crushers, and conveyor transfer points in thermal power plants and mining operations. By upgrading to ceramic rubber composite liners, industrial facilities can significantly reduce maintenance frequency, improve equipment reliability, and extend the service life of critical bulk material handling systems.

In thermal power plants, coal conveying pipes are constantly subjected to high-velocity pulverized coal erosion, making wear and tear a silent killer of equipment lifespan and operational efficiency.

Self-propagating high-temperature synthesis (SHS) wear-resistant ceramic pipes (commonly known as self-propagating composite steel pipes or SHS ceramic composite pipes) are composite pipes that combine the high strength and toughness of steel pipes with the high hardness and wear resistance of ceramics.Simply put, it utilizes a special "combustion" chemical reaction to instantly generate a dense layer of corundum ceramic inside the steel pipe. This process is called self-propagating high-temperature synthesis (SHS).To give you a more intuitive understanding, I have compiled its core definition and detailed performance characteristics for you: What are self-propagating high-temperature synthesis (SHS) wear-resistant ceramic pipes?Their manufacturing process is unique: a mixture of aluminum powder and iron oxide powder (thermite) is placed inside a steel pipe, and a violent chemical reaction is initiated by electronic ignition. This reaction instantly generates temperatures exceeding 2000℃, causing the reaction products to separate and stratify under the influence of centrifugal force.Its structure consists of three layers from inside to outside:Inner layer (ceramic layer): The main component is corundum (α-Al₂O₃), which is dense and hard.Middle layer (transition layer): Primarily molten iron, acting as a "bridge" connecting the ceramic and steel pipe.Outer layer (steel pipe layer): Provides mechanical strength and toughness, facilitating welding and installation. Product Features Extreme Wear Resistance This is its core advantage. The corundum ceramic lining has a hardness second only to diamond, significantly extending the lifespan of pipes used for conveying media containing solid particles (such as pulverized coal, ash, and mineral sand). In industries such as power generation and mining, using this type of pipe can extend its service life from a few months to several years.

Unique "Self-Propagating Combustion" Bonding Method Unlike ordinary adhesive-bonded ceramic pipes, the self-propagating combustion process uses high-temperature melting to "grow" the ceramic, transition layer, and steel pipe together, forming a metallurgical bond. This means the ceramic layer will not easily detach like adhesive patches, resulting in extremely high bonding strength and better resistance to mechanical impact.   Excellent Thermal Shock Resistance Although ceramics are usually perceived as "brittle," this composite pipe, due to the support of the steel pipe and the cushioning of the transition layer, can withstand drastic temperature changes (thermal shock) without cracking due to alternating hot and cold conditions.   Economical and Environmentally Friendly Although the initial purchase cost may be higher than that of ordinary steel pipes, its extremely long lifespan, low maintenance costs, and low operating resistance (resulting in energy savings) ultimately lead to lower overall project costs. At the same time, it does not contaminate the conveyed medium (such as molten aluminum), making it an irreplaceable material in certain industrial fields. Main Application Scenarios Based on the above characteristics, it is typically used in extremely harsh working conditions: Power industry: Ash removal and slag discharge, pulverized coal conveying. Mining and metallurgy: Tailings conveying, concentrate powder conveying. Coal industry: Coal-water slurry conveying, coal chutes. Chemical industry: Conveying corrosive gases or liquids. If you are facing conveying challenges involving high wear, high temperature, or strong corrosion, self-propagating high-temperature synthesis (SHS) wear-resistant ceramic pipes are an ideal choice.

Wear-Resistant Ceramic Materials Wear-resistant ceramic materials are a class of high-hardness, high-wear-resistant inorganic non-metallic materials made from main raw materials such as aluminum oxide (Al₂O₃), zirconium oxide (ZrO₂), silicon carbide (SiC), and silicon nitride (Si₃N₄) through molding and high-temperature sintering. They are widely used to solve wear, corrosion, and erosion problems in industrial equipment. Core Performance Characteristics Ultra-high Hardness and Wear Resistance Taking the most commonly used aluminum oxide ceramic as an example, its Mohs hardness can reach 9 (second only to diamond), and its wear resistance is 10-20 times that of high-manganese steel and dozens of times that of ordinary carbon steel. Zirconium oxide ceramics have even better toughness and can withstand higher impact loads. Strong Corrosion Resistance They have extremely high chemical stability, resisting acid, alkali, and salt solution corrosion, and can also resist organic solvent erosion, performing excellently in corrosive working conditions such as the chemical and metallurgical industries. Good High-Temperature Performance Aluminum oxide ceramics can operate for a long time below 1200℃, and silicon carbide ceramics can withstand high temperatures above 1600℃, adapting to high-temperature wear and high-temperature gas erosion scenarios. Low-Density, Lightweight Advantage The density is about 1/3-1/2 of that of steel, which can significantly reduce the load after installation on equipment, reducing energy consumption and equipment structural wear. Controllable Insulation and Thermal Conductivity Aluminum oxide ceramics are excellent electrical insulators, while silicon carbide ceramics have high thermal conductivity. Different material formulations can be selected according to needs. Disadvantages Relatively brittle and have relatively weak impact resistance (this can be improved through composite modification, such as ceramic-rubber composites and ceramic-metal composites); molding and processing are more difficult, and the customization cost is slightly higher than that of metal materials. Common types and applicable scenarios Material Type  Main Component Performance Highlights Typical Applications Alumina Ceramics Al₂O₃ (content 92%-99%) High cost-performance ratio, high hardness, excellent wear resistance Pipeline linings, wear-resistant liners, valve cores, sandblasting nozzles Zirconia Ceramics ZrO₂ High toughness, impact resistance, and resistance to low-temperature impact Crusher hammers, wear-resistant bearings, and military wear-resistant components Silicon Carbide Ceramics SiC High temperature resistance, high thermal conductivity, resistance to strong acids and alkalis Blast furnace coal injection pipelines, chemical reactor linings, heat exchangers Silicon Nitride Ceramics Si₃N₄ Self-lubricating property, high strength, thermal shock resistance High-speed bearings, turbine blades, precision wear-resistant parts Typical applications:Coal ash and pulverized coal conveying pipelines in power plants, primary and secondary air pipelines in boilers, and ash and slag removal systems.Slurry conveying, tailings conveying, and high-pressure mud pipelines in mining and mineral processing plants.Raw material, clinker powder, and pulverized coal conveying and dust collection system pipelines in cement plants. FAQ Q1: How much longer is the service life of wear-resistant ceramic materials compared to traditional metal materials? A1: The service life of wear-resistant ceramic materials is 5-20 times longer than traditional metal materials (such as high-manganese steel and carbon steel). Taking the most widely used alumina ceramic lining as an example, it can be used stably for 8-10 years in general industrial wear scenarios, while traditional metal linings usually require maintenance and replacement every 1-2 years. The specific service life will vary slightly depending on the ceramic type, working temperature, medium impact strength, and other actual working conditions. We can provide an accurate lifespan assessment based on your specific scenario parameters. Q2: Can wear-resistant ceramics withstand high-impact conditions? For example, in crushers and coal chutes. A2: Yes. Although traditional single-piece ceramics have a certain degree of brittleness, we have significantly improved their impact resistance through modification technologies such as ceramic-rubber composites and ceramic-metal composites. Zirconia ceramics themselves have extremely high toughness and can be directly used in medium-to-high impact scenarios such as crusher hammerheads and coal chute linings; for ultra-high-pressure impact conditions, we can also customize ceramic composite structures that combine the wear resistance of ceramics with the impact resistance of metal/rubber, perfectly adapting to high-impact industrial scenarios. Q3: Are wear-resistant ceramics suitable for highly corrosive conditions? For example, strong acid and strong alkali pipelines. A3: They are highly suitable. Mainstream types such as alumina ceramics and silicon carbide ceramics have extremely high chemical stability and can effectively resist corrosion from strong acids, strong alkalis, salt solutions, and organic solvents. Silicon carbide ceramics have the best corrosion resistance, especially suitable for harsh conditions involving both high temperature and strong corrosion, such as the linings of strong acid and strong alkali reaction vessels and high-temperature corrosive pipelines in the chemical industry; for ordinary corrosive scenarios, alumina ceramics can meet the requirements and are more cost-effective. Q4: Can you customize wear-resistant ceramic products based on equipment size and working condition requirements? A4: Absolutely. We support full-dimensional customization services, including product size, shape, ceramic material formula, composite structure, and installation method. You only need to provide core parameters such as equipment installation space, working temperature, medium type (wear/corrosion characteristics), and impact strength. Our technical team will design a targeted solution, and we can also provide sample testing services to ensure that the product precisely matches the working conditions.

The core reason for choosing cylindrical alumina ceramics (usually referring to alumina ceramic cylinders/rods) for ceramic-lined rubber hoses and ceramic-lined plates is that the cylindrical structure is well-suited to the working conditions of both types of products.  Furthermore, the inherent performance advantages of alumina ceramics, combined with the cylindrical shape, maximize their value in terms of wear resistance, impact resistance, and ease of installation. This can be analyzed from the following perspectives: Basic Performance Advantages of Alumina Ceramics (Core Premise)Alumina ceramics (especially high-alumina ceramics, with Al₂O₃ content ≥92%) are the preferred choice for industrial wear-resistant materials, possessing:Ultra-high wear resistance: Hardness of HRA85 or higher, 20-30 times that of ordinary steel, capable of resisting erosion and abrasion during material transport (such as ore, coal powder, and mortar);Corrosion resistance: Resistant to acids, alkalis, and chemical media corrosion, suitable for harsh environments in chemical and metallurgical industries;High-temperature resistance: Can operate continuously below 800℃, meeting the needs of high-temperature material transport;Low friction coefficient: Smooth surface reduces material blockage and lowers transport resistance;Lightweight: Density of approximately 3.65 g/cm³, significantly lower than metal wear-resistant materials (such as high-manganese steel at 7.8 g/cm³), without substantially increasing equipment load.These properties are the basis for their use in wear-resistant linings, while the cylindrical structure is an optimization specifically for the applications of ceramic-lined rubber hoses and ceramic-lined plates Key Reasons for Using Cylindrical Structures in Ceramic Rubber Hoses: The core of ceramic rubber hoses (also known as ceramic wear-resistant hoses) is a "rubber + ceramic composite," used for the flexible conveying of powder and slurry materials (such as fly ash conveying in mines and power plants). The core logic behind choosing cylindrical alumina ceramics is: Flexible Conformity: The hose needs to be adaptable to bending and vibration. Cylindrical ceramics can be arranged in an "embedded" or "adhesive" manner within the rubber matrix. The curved surface of the cylinder provides a tighter bond with the flexible rubber, making it less likely to detach due to bending or compression of the hose compared to square/plate-shaped ceramics (square ceramics are prone to stress concentration at the corners, and the edges tend to lift when the rubber is stretched). Uniform Stress Distribution: When materials flow inside the hose, they are in a turbulent state. The curved surface of the cylindrical ceramics can disperse the scouring force, preventing localized wear. The smaller gaps between the cylindrical arrangement result in more comprehensive coverage of the rubber matrix by the ceramics, reducing the risk of wear on the exposed rubber. Convenient Installation and Replacement: Cylindrical ceramics have standardized dimensions (e.g., 12-20mm in diameter, 15-30mm in length), allowing for batch bonding or vulcanization into the rubber layer, resulting in high production efficiency; if local ceramics are worn, only the damaged ceramic cylinders need to be replaced, eliminating the need to replace the entire hose, thus reducing maintenance costs. Impact Resistance: The impact toughness of the cylindrical structure is superior to that of plate-shaped ceramics (plate-shaped ceramics are prone to fracture under impact), and can withstand the impact of hard particles in the material (such as the impact of rocks in ore transportation). Key Reasons for Choosing Cylindrical Structures for Ceramic Composite Liners The core logic behind selecting cylindrical alumina ceramics for ceramic composite liners (also known as ceramic composite wear plates, used for wear protection of the inner walls of equipment such as hoppers, chutes, and mills): Anchoring Stability: Ceramic composite liners typically use a "ceramic + metal/resin composite" process. Cylindrical ceramics can achieve mechanical anchoring through casting (pre-embedding the ceramic cylinders into the metal matrix) or bonding (embedding the bottom of the ceramic cylinders into resin/concrete). The "cylinder body + bottom protrusion" structure enhances the interlocking force with the base material, providing stronger resistance to peeling and detachment compared to plate-shaped ceramics (which rely only on surface bonding and are easily detached due to material impact). Continuity of the Wear Layer: Cylindrical ceramics can be tightly arranged in a honeycomb pattern, covering the entire surface of the liner and forming a continuous wear-resistant layer; the curved design of the cylinder guides material sliding, reducing material retention on the liner surface and minimizing localized abrasion (the right angles of square ceramics tend to trap material, exacerbating wear). Adaptability to Composite Processes: The production of ceramic composite liners often uses "high-temperature cladding" or "resin casting." Cylindrical ceramics have good dimensional consistency, allowing for even distribution in the base material, avoiding unevenness on the liner surface due to ceramic size variations; furthermore, the cylindrical shape of the ceramic cylinders allows for more uniform heating during the cladding process, reducing the likelihood of cracking due to thermal stress. The selection of cylindrical alumina ceramics for ceramic-lined rubber hoses and ceramic-lined plates is essentially a dual result of "material performance + structural suitability": alumina ceramics provide core wear resistance, while the cylindrical structure perfectly matches the working conditions of both types of products (the flexibility of the hose and the anchoring requirements of the lining plate), while also considering added value such as ease of installation, maintenance, and impact resistance. This makes it the optimal structural choice for industrial wear-resistant applications.

Ceramic ball valves, with their core advantages of wear resistance, corrosion resistance, and erosion resistance, are ideally suited for applications involving the transport of solid particles and highly corrosive media. These applications place far greater demands on valve durability and reliability than in standard applications.   Core Advantages (Why Use Them in These Applications) Extreme Wear Resistance: Ceramics (especially zirconium oxide and silicon carbide) are second only to diamond in hardness, making them highly resistant to the intense erosion and abrasion caused by solid particles in the media. Excellent Corrosion Resistance: They are extremely resistant to most corrosive media, including strong acids, bases, and salts (except hydrofluoric acid and strong, hot, concentrated alkalis). High Strength and Stability: Ceramic ball valves maintain their shape and strength even at high temperatures and have a low coefficient of thermal expansion. Excellent Sealing: The ceramic ball and seat are precision-ground, achieving an extremely high sealing rating and virtually zero leakage. Core Application Industries and ScenariosThe following industries are the primary application areas for ceramic ball valves due to media characteristics or operating requirements.
