Durable Sintered Filter Tube for High-Efficiency Filtration

- Material diversity: optional stainless steel (304/316L), titanium, nickel-based alloy and other corrosion-resistant materials.

- Structural advantages: porosity up to 35-45%, pore size range 0.22-100μm, support high precision filtration.

- Deep filtration: the curved pore structure extends the impurity retention path and improves the dirt-holding capacity.

1. Size specification
- Outer diameter: 4-220mm (support customization)
- Length: 4-1000mm (up to 2000mm for special requirements).
- Wall thickness: adjusted according to the application scenario, taking into account the strength and permeability.

2. Filtering performance
- Precision: 0.22-100μm (sub-micron ultra-fine filtration can be customized).
- Porosity: 28-50%, ensuring high flow rate and low pressure loss.

3. Pressure resistance and temperature resistance
- Pressure strength: up to 2MPa (titanium material can be higher).
- Working temperature: -200℃ to 1000℃ (stainless steel material is suitable for high temperature environment).

1. Raw material processing:
- Metal powder graded and screened or screen stacked and pressed to ensure particle/screen uniformity.

2. Molding process:
- Powder is pressed and shaped by mold, or silk screen is folded into tubular structure.

3. High temperature sintering:
- Sintering at high temperature (approx. 1500°C) in a vacuum furnace to form a stable porous structure.

4. Post-treatment:
- Cleaning, polishing, surface coating (e.g. to enhance corrosion resistance).

5. Quality control and packaging:
- Porosity, pore size distribution, pressure resistance test and other full-process testing.

1. material performance:
- Resistant to strong acid, strong alkali, organic solvents, suitable for corrosive media (such as hydrochloric acid, aqua regia).
- No deformation of the aperture at high temperature, suitable for steam, thermal oil and other high-temperature scenarios.

2. structural advantages:
- Seamless one-piece molding, no shedding particles, in line with food/pharmaceutical health standards.
- Backwashing regeneration capacity, service life up to 3-5 times longer than ordinary cartridges.

3. Application flexibility:
- Can be customized tube, plate, sheet and other forms, to adapt to the needs of complex equipment.

1. Chemical and petroleum:
- Catalyst recovery, oil refining, gas desulfurization (such as hydrogenation cracking circulating oil filtration).

2. Pharmaceutical and food:
- Injection decarbonization, beverage clarification (such as mineral water, beer filtration).

3. environmental protection and water treatment:
- Industrial wastewater heavy metal removal, seawater desalination pretreatment.

4. aerospace and energy:
- Aviation fuel purification, nuclear industry coolant filtration.

5. electronics and semiconductor:
- Ultra-pure water preparation, gas dust removal (such as semiconductor production environment purification).
