Metal Tower Packing Metal Flat Ring

It was invented by German BASF, the first generation  Random packing. To compared with Raschig ring, the most important improvement is increase two row of inward ligule. It promotes liquid-gas liquidity and improve tower’ s packing’ s mass transfer performance.  

Owing to this pack’ s shape is like saddle, so called saddle ring or Berl Ring. The earliest saddle ring’ s material is ceramic. In our actual application, when gas flows upward, liquid will flow downward along with arc channel. This Movement way will directly reduce wall flow’ s happening. However, Arched external frame also cause overlapping & bridging .Therefore, scientists change two ends into rectangle type contact surface. This improvement will reduce bridging’ happen.  

Metal super raschig ring is a kind of superior metal randompacking.lt can be made from carbon steel or stainless steel. The stainless steel material is available in many types, such as SS304,SS304L,SS410 and SS316.   Metal super raschig ring is characterized by high mechanica strength,good loading capacity and uniform gas-liquid distribution.lt has better loading capacity than the metal raschicring.Compared with the general random packing, its load capacity is increased by 30%. And its pressure drop is reduced by70%.Metal super raschig ring is suitable for heavy-duty packing.Due to its unique streamlined design, it performs well in avoidincdroplet formation. This type random packing has excellent masstransfer efficiency and low operating costs. lt is widely used inthe petrochemical industry, metallurgical industries, chlor-alkalindustries and chemica industries

Flat ring is also called SMR(Super Mini Ring), It s an advanced random packing in the column tower packing. It has similar structure with cascade mini ring, There is not flanging structure at the top and bottom. It can improve the packing strength through adjust the arc of internal blade. It has reasonable flow structure, low pressure drop and high mass transfer performance. Super mini ring has two main types, which names as QH-1 and QH-2.

It is a earliest development of random packing, which its height is equal to outside diameter. Raschig Ring was invented by German Chemist Friedrich Raschig in 1914, it also marks that the development of fills hds entered a scientific track. However, in the actual application, Such as ” Wall flow, Channel flow and so on” often happened in Packed bed.  

It was invented by South China University of Technology. Unique conjugated curve finned structure can change point-to-point contacting instead of linear contacting between packing. Therefore, it promote liquid evenly distribution, avoid packing overlapping phenomenon and increase liquid gathering & dispersing etc  

It was developed by British company MTL Ltd, which also called CMR. Metal Cascade Ring is a new type of bulk packaging with the advantages of high capacity,good stain resistance and low pressure drop.Its sides have one or two beveled edges, which have hhigher mechanical strength and better gas passage than pall rings.Metal cascade rings feature a rectangular opening,curved leaves,tapered edges, and reduced height.

VSP ring also called inner arc ring. It is commonly made of stainless steel 304, 316 materials. Metallic VSP rings have reasonable geometric symmetry, which the inner arc are folded evenly along the axial direction and replaced alternated arranged.
