Import 20x20 Ceramic Rasching Ring — Buy in wholesale FOB from Supplier in China

The 20x20 Ceramic Rasching Ring is an inert ceramic packing material measuring 20mm in outer diameter and 20mm in height, forming a cylindrical ring shape with a hollow center. These Rasching rings are manufactured from high-purity alumina ceramic, typically containing 90% to 99% inert alumina content, which provides exceptional chemical resistance and thermal stability in corrosive environments. The ring structure features a wall thickness ranging from 2mm to 4mm, creating multiple internal contact points for gas and liquid distribution within industrial columns.

The ceramic material grade commonly used for Rasching rings is inert alumina (Al2O3) with a purity level of 90%-99%, often classified as technical ceramic or industrial ceramic grade. The rings are fired at temperatures exceeding 1200 degrees Celsius to achieve full densification and create a non-porous, chemically inert surface. Standard dimensions of 20x20mm are industry-standard for random packing in reactors and columns, though variations exist for specific applications. The ceramic composition provides excellent resistance to acids, alkalis, and organic solvents, making these rings suitable for demanding chemical processing environments.

These ceramic Rasching rings serve as catalyst support media and random packing material in petroleum refining, chemical processing, natural gas purification, and environmental protection equipment. They are primarily used to increase gas or liquid distribution points inside reactors and to support and protect active catalysts with low mechanical strength. Typical buyers include refinery operators, chemical plant engineers, environmental equipment manufacturers, and industrial gas processing companies. The product is traded under FOB or CIF Incoterms, with typical minimum order quantities ranging from 500kg to 1 metric ton depending on the supplier's packaging capabilities.

Zibo Win-Ceramic Material Co. Ltd is located at No.22, Changguo Western Road, Zhangdian District, Zibo, Shandong Province, China, with postal code 255000. The supplier operates under the harbor trust tier, indicating basic verification of business registration. The listing shows a response rate of 0.00% with zero average response hours, which suggests the supplier may not be actively monitoring the platform or may have limited English-language support capabilities.

The company specializes in ceramic material products including Rasching rings and other industrial ceramic packings. The listing explicitly states that these ceramic rings are used as support materials for catalyst coverage in reactors, with their main function being to increase gas or liquid distribution points and support active catalysts with low strength. The listing does not provide information about company headcount, annual revenue, production capacity, or specific certifications beyond standard industrial ceramic manufacturing practices.
