The raw materials and technical specifications of the melt filter element are as follows:
Raw Materials:
The melt filter element is primarily constructed from all-metal materials, with specific raw materials including but not limited to:
Domestic and imported stainless steel fiber sintered felt
Iron-chromium-aluminum fiber felt
Nickel fiber felt
Special stainless steel mesh
Five-layer sintered stainless steel mesh
Seven-layer sintered stainless steel mesh
The choice of these metallic filter materials depends on the requirements of specific applications, such as high temperature resistance, corrosion resistance, and strength requirements. Among them, stainless steel (e.g., SUS304, SUS316L) is often used as the primary material for melt filter elements due to its excellent corrosion resistance, high temperature resistance, and mechanical properties.
Technical Specifications:
The technical specifications of melt filter elements may vary depending on the manufacturer and product model, but the following are some common ranges:
- Working Pressure: Melt filter elements can typically withstand high working pressures, generally ranging from 2 to 30 MPa, with the specific value depending on the filter's design and materials.
- Operating Temperature: Melt filter elements have a wide operating temperature range, suitable for applications from low to high temperatures. The common operating temperature range is -60 to 500°C, and specially designed filters can even operate at higher temperatures.
- Filtration Accuracy: Filtration accuracy is one of the critical indicators for measuring filter performance. The filtration accuracy of melt filter elements typically ranges from 1 to 60 microns, selectable based on specific requirements. High-precision filters can more effectively remove tiny impurities but may increase fluid resistance.
- Filter Specifications: Melt filter elements come in various specifications to suit different application scenarios. Common specifications include diameters (e.g., φ35, φ60, φ65, etc.) and lengths (e.g., 10 to 40 inches). The filter's connection types are also diverse, such as threaded connections, flange connections, and rod connections, customizable according to user needs.
- Other Characteristics: Melt filter elements also exhibit good breathability, high dirt-holding capacity, high strength, excellent sealing performance, and long service life. Some filters also possess the characteristics of being cleanable, regenerable, and reusable, reducing usage costs.
It is important to note that the above technical specifications are merely reference ranges, and specific values should be determined according to the product manual or information provided by the manufacturer. Additionally, when selecting a melt filter element, factors such as fluid properties (e.g., viscosity, corrosivity), working pressure, and temperature must be considered to ensure that the filter's performance meets the application requirements.
