Eight-four inner arc ring (Very special packing) its meaning is excellent packing, also known as Mailer ring packing. The eight-four inner arc ring packing has reasonable geometric symmetry, good structural uniformity and high void ratio. The eight-arc ring and four-arc ring are arranged alternately along the axial direction, and each arc segment folds into the ring along the radial direction, so that the packing surface is continuous and open, and evenly distributed in space. Compared with Pall ring, the flux can be increased by 15-30%, and the pressure drop can be reduced by 20-30%.
84th inner arc ring is characterized by large opening area of ring wall, so it has the characteristics of large flux, small resistance and high mass transfer efficiency.
