Import 20x25 Ceramic Rasching Ring — Buy in wholesale FOB from Supplier in China

The 20x25 Ceramic Rasching Ring refers to a cylindrical ceramic packing element measuring approximately 20mm in outer diameter and 25mm in height, with a central opening creating a ring structure. These Rasching rings are manufactured from high-alumina ceramic material with an alumina content ranging from 90% to 99%, making them chemically inert and highly resistant to corrosion in aggressive environments. The listing indicates these rings are produced by Zibo Win-Ceramic Material Co. Ltd, a manufacturer located in Zhangdian District, Zibo City, Shandong Province, China.

The ceramic material used in these Rasching rings is typically high-purity inert alumina ceramic, which provides excellent thermal stability and chemical resistance to both acidic and alkaline media. Standard bulk density for such ceramic packings ranges from 1.1 to 1.3 g/cm3, with a typical void fraction of 70% to 80% allowing for efficient gas and liquid distribution. These Rasching rings conform to standard tower packing dimensions commonly used in industrial applications, and the rings are designed to provide high surface area per unit volume while maintaining structural integrity under operational loads.

These ceramic Rasching rings are primarily used as catalyst support materials in reactors within petroleum, chemical, natural gas, and environmental protection industries. Their main function is to increase gas or liquid distribution points throughout the reactor bed and to support and protect active catalysts that have low mechanical strength. Typical buyers include petrochemical plant operators, refinery engineering companies, and environmental equipment manufacturers requiring reliable tower packing materials for separation and reaction processes.

Zibo Win-Ceramic Material Co. Ltd is a ceramic material manufacturer located at No.22, Changguo Western Road, Zhangdian District, Zibo City, Shandong Province, China, with postal code 255000. The supplier operates under a harbor trust tier, and the listing shows a response rate of 0.00% with average response hours listed as 0, indicating limited or unavailable response performance data on this platform.

The company specializes in ceramic packings and inert ceramic materials for industrial applications. The listing explicitly states that these Rasching rings contain 90%-99% inert alumina ceramic and are used as support materials for catalyst coverage in reactors, primarily for increasing gas or liquid distribution points and protecting active catalysts. The listing does not provide information about company headcount, annual revenue, export history, or specific certifications.
