Melt Filter Element, also known as Stainless Steel Pleated Filter Element, is a fully metallic filter core welded with argon arc welding. It is primarily constructed from metal filter media such as stainless steel fiber sintered felt, iron-chromium-aluminum fiber felt, nickel fiber felt, stainless steel special mesh, stainless steel sintered five-layer mesh, and stainless steel sintered seven-layer mesh. Below is a detailed introduction to the melt filter element:
I. Product Features
- High Temperature and Pressure Resistance, Chemical Corrosion Resistance: The melt filter element can withstand high temperature and pressure environments while exhibiting excellent chemical stability, suitable for filtering various corrosive media.
- Superior Filtration Performance: The filter core boasts high porosity, excellent air permeability, and strong contaminant holding capacity, effectively blocking particles, fibers, black spots, bubbles, and other impurities to enhance product quality.
- High Strength and Good Sealing: The filter core's sturdy structure and exceptional sealing performance allow it to withstand significant pressure differences without leaking.
- Long Lifespan and Washable/Regenerable: The filter core's excellent regenerative capability enables continued use after cleaning, thereby extending its service life.
- Diverse Structures: Available in both cylindrical and pleated cylindrical configurations, the pleated design offers a filtration area 3-5 times that of the cylindrical shape, enhancing filtration efficiency.
II. Application Fields
The melt filter element is widely applied in various scenarios requiring high-precision and high-reliability filtration, including but not limited to:
- Petrochemical Industry: Oil refining, chemical production, and intermediate product separation and recovery.
- Metallurgical Industry: Filtration in hydraulic systems of steel rolling mills and continuous casting machines.
- Textile Industry: Purification and uniform filtration of polyester melts during drawing processes.
- Electronics and Pharmaceutical Industries: Pre-filtration of reverse osmosis water and deionized water, as well as pre-treatment filtration of cleaning solutions and glucose.
- Thermal and Nuclear Power Industries: Purification of oils in lubrication, speed control, and bypass control systems of turbines and boilers, as well as purification of feedwater pumps, fans, and dust removal systems.
III. Technical Parameters
The technical parameters of the melt filter element vary according to specific models and applications but generally include the following:
- Operating Temperature: Typically ranges from -60°C to 500°C, with some high-temperature filters capable of withstanding even higher temperatures.
- Maximum Differential Pressure: Typically 2MPa or higher, depending on the material and structure of the filter core.
- Filtration Accuracy: Varies from 1 micrometer to 300 micrometers, selectable based on actual requirements.
- Connection Types: Includes threaded connections, flange connections, rod connections, and other methods for convenient connection to different equipment.
