Import 20x40 Ceramic Rasching Ring — Buy in wholesale FOB from Supplier in China

The 20x40 Ceramic Rasching Ring is a cylindrical ceramic packing material measuring approximately 20mm in diameter and 40mm in length, with a typical wall thickness ranging from 2-4mm. These inert alumina ceramic rings are manufactured from high-alumina content ceramic material, commonly with alumina content between 90% and 99%, which provides excellent chemical resistance and thermal stability in aggressive industrial environments. The ring geometry features a hollow cylindrical structure with multiple internal ridges or projections that increase surface area for gas-liquid contact while maintaining low pressure drop across the packed bed.

The ceramic Rasching rings are produced from inert alumina ceramic with high purity, typically ranging from 90% to 99% Al2O3 content depending on the grade specification. Standard production uses fired ceramic with apparent porosity below 1% and water absorption less than 0.5%, ensuring minimal contamination of process fluids. The rings conform to standard industrial dimensions with tolerances of ±1mm on diameter and ±2mm on length, and the material exhibits compressive strength exceeding 150 MPa for structural integrity under heavy catalyst loads. Common variants include high-alumina (90-95% Al2O3) and super-high-alumina (95-99% Al2O3) grades for increasingly corrosive or high-temperature applications.

These ceramic Rasching rings serve as catalyst supports and tower packing in petroleum refining, chemical processing, natural gas purification, and environmental protection equipment including scrubbers and bioreactors. Primary buyers include refinery operators, chemical plant engineers, and environmental equipment manufacturers who require reliable tower internals for separation and reaction processes. The product is typically sold in metric tons with standard packaging using woven bags or jumbo bags, and buyers should verify the specific alumina content, apparent porosity, and compressive strength values before placing orders for their particular process requirements.
