High-Temperature Performance
Quartz flanges can withstand extremely high temperatures, typically above 1000°C, making them suitable for high-temperature environments, such as high-temperature steam pipes and molten metal transport systems.
Excellent Chemical Stability
Quartz flanges exhibit exceptional resistance to various chemical substances, including strong acids, strong bases, and organic solvents, which makes them highly favored in the chemical and pharmaceutical industries.
High-Purity Material
Quartz flanges are manufactured from high-purity quartz glass, allowing their use in cleanroom environments within the semiconductor and microelectronics industries as they do not release particles or chemicals that could contaminate products.
Good Mechanical Strength and Durability
Quartz flanges possess good mechanical strength and durability, maintaining their structural integrity even under repeated temperature and pressure fluctuations, thereby extending the lifespan of equipment.
Application Scenario
Chemical Industry
In the chemical industry, quartz flanges are used for pipe connections. Their corrosion resistance and high-temperature performance make them particularly suitable for acid washing, alkali washing, and similar processes, ensuring the long-term stable operation of piping systems.
Petrochemical Industry
Within the petrochemical industry, quartz flanges serve as important pipe connection components. They meet the requirements for harsh environments characterized by high temperatures, high pressure, and strong acids/bases. Their unique impact resistance makes them particularly useful for connecting pumps and valves.
Electronics and Electrical Industry
Quartz flanges are widely applied in the electronics and electrical industries, such as for connecting precision pipes in LED chip production, and oxide synthesis reactions in solar cell manufacturing. Their high purity and corrosion resistance ensure the precision connections and the purity and continuity of reaction processes.
Food Manufacturing
In the food manufacturing industry, quartz flanges can be used for transporting slightly corrosive materials as part of piping connections in food production lines. They do not contaminate or damage the food, making them an essential part of the food processing workflow.”
The primary material of quartz flanges is high-purity quartz glass, which exhibits exceptional corrosion resistance and high-temperature performance. It can effectively resist the erosion of various chemical substances, including strong acids, strong bases, and organic solvents, while maintaining stability in high-temperature environments (typically exceeding 1000°C), without deforming or melting.
Quartz flanges are widely used in industries such as chemical processing, petrochemicals, electronics and electrical, and food manufacturing. In the chemical and petrochemical industries, they are used for pipe connections involving high-temperature and corrosive media. In the electronics and electrical industries, they are used for precise pipe connections in LED chip production and solar cell manufacturing. In the food manufacturing sector, they are used for transporting slightly corrosive materials, ensuring food safety.
The maintenance and replacement cycles of quartz flanges depend on multiple factors, including the operating environment, temperature, pressure, and the type of chemical media involved. Generally, if quartz flanges are properly used and regularly maintained, their service life can be quite long. However, with increased use, they may gradually lose performance due to wear, contamination, or the formation of micro-cracks. It becomes necessary to replace them when such issues occur. The specific maintenance and replacement cycles should be determined based on actual usage conditions and the manufacturer’s recommendations.
