Какова износостойкость керамических фланцев?

---

In the harsh environment of modern industry, flanges, as key components for pipeline and equipment connections, have a direct impact on the stability and service life of the system due to their wear resistance. Traditional metal flanges face challenges in wear and corrosion conditions, while ceramic flanges, with their unique material properties, are becoming an ideal solution for high wear applications.

Analysis of Wear Resistance Performance of Ceramic Flanges
Ceramic flanges are typically made of high-performance engineering ceramic materials such as alumina, zirconia, and silicon carbide, which exhibit excellent wear resistance
-Extremely high hardness: The hardness of engineering ceramics usually reaches HRA80-90 or above, far higher than most metal materials, and can effectively resist particle erosion and mechanical wear.
-Excellent abrasive wear resistance: In fluid media containing solid particles, ceramic surfaces can reduce particle embedding and cutting effects, and the wear rate can be tens of times lower than ordinary steel.
-Низкий коэффициент трения: The ceramic surface is smooth and has a low friction coefficient, reducing wear problems caused by friction.
-Synergistic effect of corrosion resistance and wear: Ceramics have stable chemical properties and will not undergo corrosion and wear that exacerbate each other like metals.

Product application scenarios: What industrial challenges are being solved?
Ceramic flanges are particularly suitable for the following high wear conditions:

1. Mining and beneficiation industry: Pipeline systems for transporting slurry and tailings, which withstand continuous erosion of high concentration solid particles.
2. In the power and energy industry, processes such as coal powder transportation, flue gas desulfurization systems, and ash treatment involve both corrosive and abrasive media.
3. Chemical and petroleum industries: Process pipelines containing catalysts and particulate materials need to be both corrosion-resistant and wear-resistant.
4. Цементная и строительная промышленность: Raw materials, clinker, and cement transportation have high dust particle hardness and strong abrasion resistance.
5. Environmental protection and sewage treatment: Sewage and sludge conveying systems containing solid impurities.

Product Core Advantage: Why Choose Ceramic Flanges?

1. Длительный срок службы: Under the same working conditions, the service life of ceramic flanges can reach 5-10 times that of ordinary steel flanges, greatly reducing replacement frequency and maintenance costs.
2. Significant reduction in maintenance costs: reducing downtime for maintenance, improving equipment continuous operation efficiency, and achieving significant overall economic benefits.
   -Stability and reliability: Ceramic materials have stable performance and will not undergo property changes due to environmental changes, ensuring long-term reliable operation.
3. Multiple structural forms: Provides various options such as integral ceramic flanges, ceramic composite flanges (ceramic lining+metal shell), etc., to adapt to different pressure levels and installation needs.
4. Customized design capability: can optimize ceramic material formula and structural design based on specific working conditions, medium characteristics, particle size, flow rate and other parameters.

Customer case sharing (anonymous processing)

1. A large mining group: We have adopted our alumina ceramic composite flange in the concentrate transportation pipeline to replace the original high chromium cast iron flange. Under harsh conditions with a solid particle concentration of 60% and a flow rate of 2.5m/s, after 18 months of use, the wear of the ceramic lining was found to be less than 0.5mm, while similar parts of the original system need to be replaced every 6 months. Expected to reduce annual maintenance costs by 70% for a single point.
2. A certain thermal power plant: Install our silicon carbide ceramic flange on the limestone slurry pipeline of the flue gas desulfurization system. The previously used duplex steel flange experienced severe wear, corrosion, and perforation on average every 4 months in a medium containing chloride ions and solid particles. After replacing the ceramic flange, it has been running continuously for 24 months without any abnormalities, solving the frequent leakage problem.
3. A certain chemical enterprise: We use our customized zirconia ceramic flange on the key pipeline for catalyst transportation, which can withstand high temperature, high pressure, and catalyst particle erosion. After three years of operation, the flange sealing surface was found to be intact, avoiding the risk of catalyst leakage caused by flange failure and ensuring continuous production safety.

Ceramic flanges, with their excellent wear resistance, have demonstrated irreplaceable value in high wear conditions in many industrial fields. Its long service life, low maintenance requirements, and excellent stability have brought significant economic benefits and operational reliability to industrial enterprises. Choosing the appropriate ceramic flange solution can fundamentally solve the frequent maintenance, leakage, and shutdown problems caused by pipeline system wear.
