Overview
The perforated window blades of the DN38 stainless steel flat ring packing ring wall have been changed from the traditional open type inner curved tongue plate to a continuous inner curved arc-shaped rib plate, and the flanging at the end of the ring wall has been eliminated.
Product Details
DN38 stainless steel flat ring packingThe height to diameter ratio of the packing is 1/3, and the flanging of the stepped ring is eliminated. Inner curved ribs are used to improve the strength of the packing. The flow channel structure is arranged in an orderly manner during disorderly stacking, and the pressure is reduced. Both processing capacity and mass transfer energy are improved.

Due to structural changes, the stainless steel flat ring packing has reduced the convergence and dispersion points formed by the flanging of the ring and the endpoints of the inner curved blades in the packing layer. Especially suitable for relative flow between liquid and liquid phases, reducing the convergence of dispersed liquid clusters at this location; The symmetrical and uniform internal curved rib structure has a good impact on the uniformity of fluid flow, promoting the dispersion convergence redispersion cycle of the liquid pool group, effectively reducing the axial backmixing of the packing layer, and improving the mass transfer efficiency between the liquid and liquid phases. This type of packing material has achieved good technical and economic results in the extraction process of liquid-liquid mass transfer.
Stainless steel flat ring, also known as inner curved arc ring packing, is used in liquid-liquid extraction processes of low interfacial tension systems. Its performance is significantly better than that of Ball ring and saddle ring packing, with small axial mixing and large processing capacity. Its mass transfer efficiency can be improved by more than 20%.
