Metal Random Packing

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

Dixon ring packing, as a widely used packing material in laboratories, belongs to metal materials and is also a type of small particle packing. It is made of metal sheet and has a diameter equal to its height.  

Triangular spiral packing is made by winding metal wires, and its shape is similar to that of a spring. It is also known as triangular elastic packing and belongs to Fenske Spiral packing. The difference between it and a bullet is that each circle it wraps around is not a circle but a triangle, and the triangles between circles are offset by a certain angle. Therefore, from the end face direction, it is a polygonal shape, which has higher filling efficiency.  

Copper Intalox saddle rings combine the benefits of Intalox saddle ring packing with the properties of copper.    Characteristics Material: Made from copper, which offers excellent thermal and electrical conductivity. Shape: The saddle shape allows for efficient packing and maximizes surface area for gas-liquid interactions. Corrosion Resistance: Copper provides good resistance to certain chemicals, making it suitable for specific environments.

Metal tellerette ring packing is made of sheet metal stamping, stretching into specific calender, mesh surface into the rules of the diamond mesh, wire mesh corrugated packing geometric rules. Garland filler available various materials processing, material selection of a wire mesh packing is wide, and corrosion resistant performance is good.Garland filler has a wreath of plastic packing and garland filler metal.The wreath of plastic packing appear earlier, and more for gas washing, purification tower.Metal Tellerette Packing like ellipse is made of many enlaced cirques. Due to its high liquid storage in lacuna of packing, it prolongs time of gas-liquid contact, enhance the efficiency of transfer, It has the characteristic of big voidage, low pressure drop, sufficiency gas-liquid contact,low weight.

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.

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 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.

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.
