Stainless steel step ring material is 304 316L stainless steel step ring packing metal random packing manufacturer

Product varieties are all kinds of silicone oil, silicone rubber, silicone surfactant additives, silicone softener series, fabric refining washing and finishing auxiliaries and solar silicon wafer cleaning agent and a series of products.

Keywords: all kinds of silicone oil, cleaning agent

Stainless steel step rings feature a tapered flare on one end. The main function of the expansion is to improve the stacking of fillers in the tower, so that the fillers basically become point contacts, increase the gaps between adjacent fillers, and eliminate the source of liquid accumulation pools.

 1. Product introduction of stainless steel ladder ring packing              

  Stainless steel step rings feature a tapered flare on one end. The main function of the expansion is to improve the stacking of fillers in the tower, so that the fillers basically become point contacts, increase the gaps between adjacent fillers, and eliminate the source of liquid accumulation pools.

   The height of the metal/stainless steel step ring is about half the diameter. One side of the ring has a tapered flange, a window hole is opened on the ring wall, and a curved blade extends toward the center of the ring. Due to the reduced height and the special structure of the tapered flange, it not only improves the gas-liquid distribution in the packing layer, but also increases the gas-liquid contact points, which is conducive to the convergence and dispersion of liquid and the continuous renewal of the liquid film surface, which strengthens mass transfer and separation. Efficiency is greatly improved. Generally, the flux of stepped ring packing is 10-20% higher than that of Pall ring packing, and the pressure is reduced by 30-40%.

3. Application of stainless steel ladder ring products

      At present, a large number of metal step rings have been put into operation, with a diameter of up to 12 meters. Products are widely used in oil refining, sulfuric acid, methanol, and synthetic ammonia. For example, in an oil refining unit, if the floating valve tray of the gasoline stabilizing tower is replaced with a stainless steel ladder, its production capacity will be increased by 35%, the number of mass transfer units will be increased by 70%, and the operating flexibility will be doubled. In addition, stainless steel metal step rings are also used in equipment such as methanol absorption and distillation towers, crude oil vacuum distillation towers, and ammonia synthesis gas CO2 absorption and regeneration towers.

Product inquiry

With strong technical force and complete testing means, the enterprise has passed the ISO9001 quality system certification. All kinds of tower internals, tower and packing products are widely used in oil refining, chemical industry, telephone fee, caustic soda, sulfuric acid, electric power, sewage treatment, coking gas and pharmaceutical industries, and are well received by users.
