Production process of our Sintered Pleated Filter Cylinder
Screening stainless steel powder or fiber mat, mixing additives to enhance sintering performance.
- Folding process: Fold metal mats or woven mesh into corrugated shape to increase the surface area.
- Press molding: The mold presses the powder into a hollow cylindrical embryo under high pressure.
Sintering at about 1500℃ under vacuum environment to form a stable porous structure.
Cutting, welding end caps (argon arc welding to ensure sealing), surface polishing and anti-rust treatment.
Advantages of our Sintered Pleated Filter Cylinder
The folded structure increases the dirt-holding capacity by more than 50%, suitable for highly viscous liquids and gases.
Acid and alkali resistance, organic solvent corrosion, no deformation under high pressure difference (pressure up to 6.9MPa).
Support backwashing, chemical cleaning (such as 0.1N NaOH or citric acid) and ultrasonic regeneration, reuse rate up to 90%.
Long-life design reduces the replacement frequency, and the comprehensive cost is lower than the disposable cartridge.
All stainless steel material without fiber shedding, in line with the food, pharmaceutical industry health standards.

Frequently Asked Questions
It is a high-strength filtration component made by folding stainless steel wire mesh or fiber felt and then sintering it in a vacuum furnace. The pleated structure significantly increases the effective filtration area.
The pleated structure increases the surface area by more than 50%, which dramatically improves dirt-holding capacity, lowers flow resistance, and extends the service life between cleanings.
Yes, they are highly cleanable. They support backwashing, ultrasonic cleaning, and chemical washing (using citric acid or 0.1N NaOH), with a regeneration rate of up to 90%.
Depending on the material selected (e.g., 316L, Hastelloy), they can operate in temperatures ranging from -200°C to 600°C (up to 1000°C for special alloys) and handle working pressures up to 30MPa.
Yes, we support full customization for non-standard requirements. We offer diameters from 25mm to 180mm, lengths from 100mm to 1500mm, and interfaces like threaded, flange, 222, 226, and fast cards.
