Our company's metal loose-fill workshop is currently producing Rasching rings made of stainless steel 304 with specifications DN25*0.5. These Rasching rings have low resistance to filling material and high flow capacity. Rasching rings are one of the earliest artificial fillings used in industry. They are typically made of ceramic or metal sheets, with the height equal to the diameter, and common sizes range from 25mm to 75mm (with some as small as 6mm and as large as 150mm). The ceramic wall thickness is 2.5mm to 9.5mm, and the metal ring thickness is 0.8mm to 1.6mm. The wall of the ring should be as thin as possible within the allowable strength. Although Rasching rings have less than ideal mass transfer performance, they are still chosen by some factories due to their simple structure, ease of manufacturing, and lower cost.
Lashing ring material:
Metal swing ring specification model DN25, made of stainless steel 304 material, features low packing resistance and high flow rate. It is a ring packing with a fixed geometric shape in the history of tower packing, characterized by the outer diameter and height of the packing ring being equal. Jiangxi Province Pingshang City Huanxing Chemical Industry Co., Ltd. has mature technology and complete production equipment, including 36 plastic machines, 10 corrugated plate packing production lines, 15 stamping machines, 6 shearing machines, and 6 automatic spot welding machines. Each workshop is equipped with a laboratory and has complete inspection equipment to monitor product specifications in real-time on the production line and adjust production methods based on test data. The quality control department is equipped with standard inspection items, ensuring the pass rate of outgoing products.
Metal Swing Check DN25*0.5, 304 stainless steel, with small filling resistance and high flow rate, simple structure, and low price; however, it has issues like uneven liquid distribution and severe wall and沟流. Plastic: Polyethylene (PE), Polypropylene (PP), Polyvinyl Chloride (PVC), Polyvinylidene Fluoride (PVDF), Chlorinated Polyvinyl Chloride (CPVC), Reinforced Polypropylene (RPP). Metals: Carbon Steel, Stainless Steel 304, 304L, 410, 316, 316L. Features: The outer diameter and height of the filling ring are the same, simple structure, cost-effective; however, it has issues like uneven liquid distribution and severe沟流 and wall flow.
Common Specifications and Models:
The metal Rasching ring specification with DN25 and made of stainless steel 304 material was developed by F. Rasching in 1914. It is one of the earliest invented fixed-geometry random packing materials. Its shape is simple, with the height equal to the diameter. Large-sized Rasching rings (over 100MM) are generally filled uniformly, while those below 75MM are usually filled in a random manner. Metal Rasching rings are widely used in various fields, but their primary application is as a catalyst support. The material for metal Rasching ring packing can be various, such as carbon steel, stainless steel 304, 304L, 410, 316, 316L, etc., available for selection.
