Composite Sintered Filter Element 50x70

We are one of the professional composite sintered filter element 50x70 manufacturers specialized in offering you high-quality composite sintered filter element 50x70. If you want to buy one, please feel free to contact us.

The composite sintered filter element 50x70 is a high-performance sintered metal filter element manufactured by sintering a perforated plate with multiple layers of stainless steel wire mesh under high temperature and vacuum conditions.

Unlike conventional single-layer mesh filters, the composite sintered filter element combines the structural strength of a perforated plate with the filtration performance of multi-layer stainless steel wire mesh. This unique construction results in a rigid, porous filtration medium that maintains uniform pore size, withstands high pressures, and provides reliable filtration performance in the most demanding industrial environments.

• 304 stainless steel: good corrosion resistance, good heat resistance, and relatively low price. Suitable for filtration in general corrosive environments, such as food, chemical, water treatment and other industries

• 316 stainless steel: with stronger corrosion resistance and better high-temperature resistance, it is suitable for more harsh environments, such as chemical, pharmaceutical, seawater desalination and other industries

• 316L stainless steel: The low-carbon version of 316 stainless steel has better intergranular corrosion resistance and is suitable for environments with extremely high corrosion resistance requirements

• 304L stainless steel: a low-carbon version of 304 stainless steel with better intergranular corrosion resistance, suitable for environments with certain requirements for corrosion resistance but cost sensitivity

The Composite Sintered Filter Element 50x70 is widely used across multiple demanding industries:

• Petrochemical & Oil Processing: Filtration of oils, polymers, and chemical intermediates
• Pharmaceutical Manufacturing: Liquid filtration, API purification, sterile processing
• Chemical Processing: Corrosive liquid and gas filtration, catalyst recovery
• Polyester & Chemical Fiber: Melt filtration, polymer purification
• Water Treatment: Industrial water purification, wastewater treatment
• High-Temperature Gas Filtration: Flue gas treatment, high-temperature process gas purification
• High-Temperature Liquid Filtration: Thermal fluid filtration, high-temperature process liquids

What is Composite Sintered Mesh?

Why Stainless Steel?

• Excellent corrosion resistance: Withstands acidic, alkaline, and chemically aggressive environments
• High-temperature stability: Maintains strength and integrity at elevated temperatures up to 816°C
• High mechanical strength: Rigid structure withstands high pressures without deformation

Composite vs. Standard Sintered Mesh

• Higher mechanical strength: Perforated plate support provides superior pressure resistance
• Greater structural stability: Rigid construction resists deformation under high differential pressures
• Enhanced durability: Withstands fluid impacts and pressure surges
• Longer service life: Robust construction extends operational life
