Introduction to Different Types of Flanges
A flange is a mechanical connector used for pipeline connections, typically composed of two disk-shaped flange plates, a specific number of bolts, and gaskets. The flange plates have a series of flange holes, and bolts are used to tightly compress the two flange plates together, creating a sealed structure at the pipeline junction.
The primary function of flanges is to connect pipelines and equipment, enabling them to function as a unified system for the transport and handling of media. Flanges can achieve varying degrees of sealing by replacing different types of gaskets and adjusting bolt tightness, thereby adapting to different media and operating conditions.
Flanges are classified by material into various types, including metal flanges, plastic flanges, and ceramic flanges. Each type offers different sealing effects and application ranges, requiring selection based on specific requirements and ensuring compliance with relevant standards and specifications to ensure the safety and reliability of pipeline connections.
·Steel Flanges：Steel flanges are the most widely used type in the market, boasting a high market share due to their lower manufacturing cost. They are suitable for low-pressure, low-temperature applications such as construction, water supply, and drainage.
·Stainless Steel Flanges：Stainless steel flanges are increasingly becoming a mainstream product with growing market share annually. They offer excellent corrosion resistance and high-temperature performance, making them suitable for environments such as petroleum, chemical, and aerospace industries where high temperatures, pressures, and corrosive conditions prevail.
·Cast Iron Flanges：Cast iron flanges also hold a significant market share, primarily used in low-pressure, low-temperature, and mildly corrosive environments like water supply, drainage, air conditioning, and heating systems.
·PVC Flanges：PVC flanges have a narrower application range in the market, suitable for mildly corrosive media applications such as chemical and construction fields.
·Ceramic Flanges：Ceramic flanges trace back to the 1950s when the rapid growth of the chemical and petroleum industries demanded higher corrosion resistance from pipelines and equipment, surpassing the capabilities of traditional metal flanges. Ceramic materials, initially alumina ceramic using sintering processes, were employed to address these deficiencies, offering excellent corrosion resistance, wear resistance, and high-temperature performance.
High Purity Alumina Ceramic Flanged Bushings
With the continuous emergence and development of new ceramic materials such as silicon carbide, silicon nitride, and zirconia, the performance of ceramic flanges has been continuously enhanced and improved. They find extensive applications in sectors such as chemical industry, petroleum, aerospace, and new energy, particularly suitable for the conveyance and handling of media under harsh conditions such as high temperature, high pressure, strong corrosion, and severe wear.
However, due to the high manufacturing cost and relatively complex manufacturing processes of ceramic flanges, it is essential to comprehensively consider factors such as performance and cost when selecting ceramic flanges, making a scientifically reasonable choice based on actual circumstances. Moreover, attention to specific technical requirements during installation and maintenance is necessary to ensure their safety and reliability.
