Import 55x36mm Alumina Ceramic Six Wing Ring — Buy in wholesale FOB from Supplier in China

The 55x36mm Alumina Ceramic Six Wing Ring from Zibo Win-Ceramic Material Co. Ltd is a precision-formed tower packing component manufactured in Zibo, Shandong Province, China. The ring measures 55mm in outer diameter and 36mm in height, with a six-wing internal structure that creates multiple gas-liquid contact points. The alumina content ranges from 90% to 99%, placing this grade in the high-purity alumina ceramic category used for catalytic support and mass transfer applications. The supplier states inert properties of 90%-99%, indicating suitability for environments where chemical reactivity must be minimised.

The material structure consists of sintered alpha-alumina (corundum), a standard ceramic phase for industrial tower packing. The six-wing geometry, also known as a modified Pall ring or cross-partition design, increases surface area and improves fluid distribution compared to simpler ring shapes. Typical manufacturing for this product category involves isostatic or dry-press forming followed by high-temperature sintering at 1600-1700 degrees Celsius. The resulting porosity and crystal structure determine crush strength and thermal shock resistance, both critical for reactor bed longevity. Standard industry tolerances for this size class are typically plus or minus 1mm on diameter and plus or minus 0.5mm on height.

Applications span petrochemical refining, syngas production, ammonia synthesis, and environmental gas treatment systems where the ring serves as both packing media and catalyst carrier. Buyers include engineering procurement contractors, catalyst manufacturers, and plant operators in the fertiliser, oil refining, and chemical synthesis sectors. The supplier indicates availability with FOB and CIF shipping terms. Buyers should confirm the specific alumina grade (90%, 95%, or 99%), bulk density, and crush strength with Zibo Win-Ceramic Material Co. Ltd directly, as these parameters determine compatibility with specific reactor designs and operating pressures.

Zibo Win-Ceramic Material Co. Ltd is located at No.22, Changguo Western Road, Zhangdian District, Zibo City, Shandong Province, 255000, China. The company operates from the Zibo industrial corridor, a region with established ceramic manufacturing infrastructure. The supplier holds a harbour trust tier, which represents an entry-level verification status on the platform. The response rate is recorded at 0.00% with zero average response hours, indicating that direct enquiry through the platform may not yield rapid feedback. Buyers should consider alternative contact methods or allow extended timelines for initial communication.

The supplier profile does not list specific factory size, annual output, year of establishment, or named client references. No independently verified ISO or SGS certificate numbers are provided in the available data, despite these certifications being mentioned in the source description. The product focus appears to be industrial alumina ceramics for chemical process industries, with the six-wing ring representing one geometry in a broader tower packing portfolio. Buyers should request a company profile, factory audit report, or reference installations before committing to volume orders. The Shandong location offers access to Qingdao Port for international shipment, a logistical factor worth confirming for containerised cargo.
