Application of Silicon Carbide Ceramics in Wear-Resistant Piping

---

As a high-performance fluid conveyance solution, silicon carbide ceramic wear-resistant piping is gradually becoming the material of choice in industrial wear applications due to its extremely high hardness and chemical stability. This article aims to demonstrate, through objective technical analysis and real-world case studies, how this material extends equipment lifespan, reduces maintenance costs under extreme operating conditions, and provides customized conveyance solutions for various industries.

Faced with production downtime caused by frequent pipeline replacements and corrosion challenges posed by strong acids and alkalis, our silicon carbide wear-resistant pipelines offer a fundamental solution. They effectively withstand high-velocity particulate erosion, extending pipeline service life to several times that of ordinary steel pipes, while eliminating leakage risks associated with the conveyance of complex media to ensure the continuity and safety of production systems.

Advantages and Technical Specifications
Our products are manufactured in strict compliance with industry standards such as JCT2846-2024. Through advanced sintering processes, the pipes are endowed with exceptional physical and chemical properties.

1. Unparalleled Wear Resistance: Silicon carbide boasts a hardness comparable to diamond, with wear resistance more than 30 times that of ordinary steel pipes. In sandblasting abrasion tests, wear is strictly controlled to within 3.5 cm³, effectively resisting cutting and scouring by high-hardness particles.
2. Exceptional Corrosion Resistance: Whether in environments with strong acids, strong alkalis, or chloride ions, silicon carbide ceramics exhibit excellent chemical inertness. This makes them an ideal choice for transporting corrosive media in chemical, metallurgical, and desulfurization systems.
3. Diverse Bonding Methods: We offer a variety of processes, including oxide-bonded, silicon nitride-bonded, and precast silicon carbide castable pipes. Among these, the silicon nitride-bonded type offers the highest mechanical strength (flexural strength ≥ 40 MPa) and is suitable for high-load applications, while precast castable pipes are better suited for customizing complex-shaped pipelines.
4. Flexible Customization: We support customization ranging from φ20 mm to φ740 mm and even larger diameters. Whether for straight pipes, elbows, or reducer tees, we can provide precise dimensional matching based on the customer’s on-site conditions and flow velocity requirements (particularly for flow velocities > 15 m/s).

Typical Application Cases and Operating Condition Analysis
To more vividly demonstrate the product’s value, the following analysis combines real-world applications from the power and chemical industries.
In the ash conveyance system of a 600 MW coal-fired power unit, the system faced the severe challenge of high-speed ash particle erosion. The system was retrofitted with NM-YT-ZG-400 silicon carbide pipes. Operational data shows that after 8,000 hours of continuous operation, the detected wear volume was only 2.1 cm³. Compared to traditional alloy pipes, this represents a more than threefold increase in service life, significantly reducing maintenance frequency.

In the lime production process for soda ash manufacturing, pipes must withstand both physical abrasion from slurry and chemical corrosion from acidic and alkaline solutions. A certain chemical plant upgraded its existing standard ceramic and ductile iron pipes to silicon carbide wear-resistant pipes for conveying weakly acidic solutions from electrostatic precipitators and lime slurry. After long-term operational monitoring, no significant leaks were observed in the pipes, successfully resolving the issue of frequent replacements previously caused by insufficient material hardness or poor corrosion resistance.
