Standard Five-layer Sintered Mesh

China leading 5-layer Sintered Wire Mesh Manufacturer

The standard five-layer sintered mesh is a high-performance gradient filter material that is made by melting and compounding five layers of stainless steel wire mesh with different functions through a high-temperature diffusion sintering process. Its core value lies in the precise layered design that achieves high strength, high precision, and large dirt holding capacity while maintaining high porosity. The following is a detailed analysis:

Composition and function of five-layer sintered mesh structure

Protective layer, 12~40 mesh (500~2000μm) can withstand fluid impact, intercept large particles of impurities, prevent mechanical damage to the filter layer , sacrifice layer, and extend the life of the core layer ;

Transition layer , 40~100 mesh (150~400μm) pre-distributes the fluid, guides the particles to deposit evenly on the filter layer, relieves clogging pressure , distributes flow, and protects the filter layer .    

Filtration layer , 100~800 mesh (18~150μm) core precision control layer, to achieve target particle size interception (precision 1~100μm customizable) , surface filtration + deep filtration combination ;

Transition layer , 40~100 mesh (150~400μm) symmetrical structure, supports the filter layer and disperses the reverse cleaning pressure to resist crushing, ensuring backwash stability ;

Support layer , 12~40 mesh (500~2000μm) provides a rigid skeleton to withstand the system pressure difference (up to 10MPa+), prevent the filter material from deforming , and mechanically bear the main body .

After each layer of wire mesh is stacked in sequence, it is sintered at high temperature (1100~1300℃) in a vacuum/hydrogen protection furnace to fuse the intersections of the metal wires into a metallurgical bonded whole.

Core performance advantages of standar five-layer sintered wire mesh

1. Gradient filtration, high dit holding capacity

- Impurities are intercepted layer by layer (large particles → protective layer, medium particles → transition layer, fine particles → filtration layer), avoiding rapid clogging of a single layer and increasing the dirt holding capacity by 3-5 times.

2. Anti-pressure difference & Anti-fatigue

- The support layer + double transition layer form an "I-beam" structure, with a compressive strength more than 10 times that of ordinary metal mesh (>15MPa), and no deformation after 100,000 pulse backwashes.

3. Absolute precision control

- The filter layer adopts plain dense weave or Dutch twill weave, with a pore size tolerance of ±3μm (such as nominal 20μm, actual 17~23μm).

4. Zero material migration

- Full metal metallurgical bonding, no adhesive, no fiber shedding, meets ASME BPE, FDA food grade requirements (material: 316L/304).

5. 100% Renewable

- Resistant to ultrasound, acid and alkali immersion, high temperature calcination (<800℃), flux recovery rate>95%.

Typical application scenarios of standard five-layer sintered wire mesh

1. High-pressure hydraulic system

- Aviation fuel filtration: precision 10μm, pressure bearing 25MPa (support layer enhanced design)

2. Chemical catalytic recovery

- Pt catalyst interception: accuracy 5μm, resistant to 98% sulfuric acid + 80℃ environment (material: Hastelloy)

3. Biopharmaceuticals

- Sterile liquid terminal filtration: precision 0.22μm (composite microporous membrane), in line with GMP certification

4. High temperature gas purification

- Coke oven gas dust removal: accuracy 50μm, resistant to 450℃+H₂S corrosion (material: 310S stainless steel)

5. Chip Manufacturing

- Ultrapure water delivery: 1μm precision, no metal ion release (electrolytic polishing + ultrasonic cleaning)

                                                                                                                                          500 mesh sintered wire mesh

Key parameters of standard five-layer sintered wire mesh

1. Material: 316L (general purpose), 304 (economical), Monel (seawater resistant)

2. Accuracy: marked as “absolute filtration accuracy”

3. Flux: Measure the initial pressure drop (e.g. ΔP < 5kPa when the water flow rate is 1m³/h)

4. Size: standard round pieces (Φ20~600mm) or customized special-shaped pieces (3D drawings are required)

The standard five-layer sintered mesh is a "functional gradient composite material" achieved through precision lamination and high-temperature sintering technology. Its five-layer collaborative design (protection → transition → filtration → transition → support) solves the problem that traditional filter materials cannot have both strength and precision. It is suitable for industrial filtration scenarios with strict requirements on reliability, precision life, and resistance to extreme environments, especially in the fields of hydraulics, chemicals, energy, etc. Dashang Wire Mesh provides customers with sintered filter materials with superior performance, and provides the best filtration solutions from three dimensions : material compatibility, absolute precision, and burst strength .
