Керамическая Берл кольцо

Berl saddle is an opening packing shaped like a saddle without inside and outside, the berl saddle performs better as compared to Raschig rings in the aspects of even fluid distribution and low resistance. And it makes lower pressure against the inner wall of the tower than the ring packing. However, it's easy to nesting due to its opening construction, and more easy to be fragile than Raschig ring at the bed plate.They are available in variable sizes such as (mm): 19,25,38,50Physical PropertiesSizeWeight(Kg/m3)Number(pcs/m3)Surface(m2/m3)Free volume (%)3/4”(19mm)72583950225581”(25mm)64043250206611.5”(38mm)61712775110722”(50mm)65079009572Chemical CompositionSiO2Al2O3Fe2O3K2O+Na2OCaO>70%17-23%<1%2-4%<1-2%
