Filter element

Filter cartridges are widely used in industries such as petroleum, chemical, medical, high-temperature gas filtration, research, metallurgy, food, and machinery. The main filter material used is 304, 304L, 316, and 316L stainless steel fiber sintered felt and stainless steel woven mesh as the primary filtering media. The sealing surfaces of the filter cartridges are joined using argon arc welding, and the filter layers are created using a multi-fold folding process, forming a complete filter cartridge without leakage or media detachment. Stainless steel fiber sintered felt is a porous depth filtration material made from stainless steel fibers through high-temperature sintering, while stainless steel woven mesh is woven from stainless steel wires.

Characteristics of filter cartridges:

Stainless steel precision filter cartridges have a high porosity rate, good air permeability, low resistance, and low pressure drop.
When folded, stainless steel precision filter cartridges have a large filtration area and high dirt-holding capacity.
Stainless steel precision filter cartridges are resistant to high temperatures and suitable for filtering high-viscosity liquids.
They have good regeneration performance and can be repeatedly used through chemical cleaning, high temperature, and ultrasonic cleaning.
The filter cartridges have a fully stainless steel structure, ensuring wide chemical compatibility.
Key technical parameters:

Maximum working temperature of stainless steel precision filter cartridges: ≤500°C.
Filtration accuracy: 1-200 μm.
Operating pressure: 0.1-30 MPa.
Filter cartridge specifications: 5-40 inches (can be customized according to user requirements).
Interface types: 222, 226, 215, M36, M28, M24, M22, M20 threaded interfaces, etc.
"Filter cartridge" is a term commonly used in the filtration industry, and one type of filter cartridge uses multiple layers of stainless steel sintered mesh.

Filter cartridges have various pore sizes (28%-50%), aperture sizes (4 μm-160 μm), and filtration accuracies (0.2 μm-100 μm). The channels crisscross each other, making them resistant to high temperatures, rapid cooling, and rapid heating. They also have corrosion resistance and are suitable for various corrosive media such as acids and alkalis. Stainless steel filter cartridges can withstand general acid, alkali, and organic corrosion, making them particularly suitable for filtering sulfur-containing gases. They have high strength and good toughness, making them suitable for high-pressure environments. They can be welded and easily installed or removed. The pore shape is stable, evenly distributed, and provides stable filtration performance. They have excellent regeneration performance, with filtration performance recovery of over 90% after repeated cleaning and regeneration.

Filter cartridges are used in various applications such as petrochemical and oilfield pipeline filtration, refueling equipment and construction machinery fuel filtration, water treatment equipment filtration, pharmaceutical and food processing, etc. The rated flow ranges from 80 to 200 L/min, and the working pressure is between 1.5 and 2.5 Pa. The filter area ranges from 0.01 to 0.20 m², and the filtration accuracy ranges from 2 μm to 200 μm. The filter material used can be stainless steel woven mesh or stainless steel perforated mesh. They are used for primary water removal in heavy oil combustion systems and can also be used for liquid filtration in chemical industry applications with a precision of 100 μm. They are suitable for pre-treatment and post-treatment systems in industries such as electronics, petroleum, chemical, pharmaceuticals, and food processing. They further purify water with low suspended impurities (less than 2-5 mg/L).
