Professional FAQ: Pressure Arc Sieve & Related Technologies
Pressure Arc Sieve – Technical FAQ
1. What is the primary material for pressure arc sieve?
Pressure arc sieves are typically fabricated using AISI 304 or 316L stainless steel for maximum corrosion resistance, but special applications may require duplex, 904L, or Hastelloy for aggressive processes.
2. What slot opening should be selected?
Slot opening depends on separation requirements—ranging from 0.05mm (ultra-fine) for food and pharma, to 2mm for municipal and mineral filtration. Precision control ensures optimal clog-free operation.
3. How are the arc angles determined?
Arc angle (usually 45°, 60°, 90°, or 120°) is engineered according to feed flow, system layout, and pressure drop parameters. A steeper arc increases dewatering efficiency.
