SS410 PALL RINGS

   SS410 PALL RINGS, pall rings are Improved by the development of Raschig rings made ​​of a particulate filler. 
Raschig ring is in the wall to open a row or two rows of square hole is made at the original opening material is
not removed, but the bend into the tongue into the ring, a few slices of tongue lap up the center of the ring. Thus, in the packing surface area does not reduce the case to increase air flow channel, and are conducive to gas, liquid distribution into the ring and make them even more perfect, thus increasing the effective two-phase contact area. Compared with Raschig ring, a throughput capacity and mass transfer performance has improved significantly.

For different usuage, pall rings can be  made ​​of SS410, SS304, SS304L, SS316, SS316L, PTFE, PE,PE, PP+10%FG, PVC, CPVC, PVDF, PEEK, CARBON, CERAMIC ETC.
