Import 55x52mm Alumina Ceramic Six Wing Ring — Buy in wholesale FOB from Supplier in China

The 55x52mm Alumina Ceramic Six Wing Ring is an structured tower packing manufactured from aluminium oxide ceramic with purity grades ranging from 90% to 99%, supplied by Zibo Win-Ceramic Material Co. Ltd from their facility in Shandong Province, China. This six-wing geometry, measuring 55mm in outer diameter by 52mm in height, provides a specific surface area and void fraction engineered to optimise gas-liquid contact efficiency in packed column applications. The supplier sources raw alumina from Zibo, a recognised centre for advanced ceramic production in China, and forms the rings through isostatic pressing or extrusion followed by high-temperature sintering. The wing structure creates radial gas distribution channels while maintaining mechanical crush strength sufficient for deep bed installations in catalytic reactors and absorption columns.

Material composition centres on alpha-alumina (corundum phase) with controlled silica, iron oxide and alkali content to ensure chemical inertness across pH 1-14 and thermal stability to 1700 degrees Celsius in oxidising atmospheres. Typical bulk density for this geometry falls between 700-900 kg per cubic metre depending on wall thickness and alumina percentage, with a void fraction exceeding 70% to minimise pressure drop. The 55x52mm dimension places this ring in the medium-to-large packing category, suitable for columns above 800mm diameter where uniform liquid distribution becomes critical. Standard surface finish is unglazed and as-fired, though some applications may demand diamond-turned edges or controlled surface roughness to prevent fluid channeling at high vapour velocities.

Primary buyers include petroleum refineries for catalytic reforming and hydrocracking unit support beds, chemical manufacturers running continuous distillation or scrubbing operations, and environmental engineering firms designing flue gas desulphurisation systems. The ring's six-wing profile resists nesting and promotes self-supporting bed structure, reducing the risk of void formation that plagues simpler Raschig or Pall ring designs. For import procurement, confirm the exact alumina percentage (90%, 92%, 95%, 99%) as this directly affects both price and performance in high-temperature sulphuric acid environments. Packaging is typically in moisture-resistant woven polypropylene bags on wooden pallets; sea freight from Qingdao Port to most Asian or European destinations runs 14-25 days depending on liner schedules.

Zibo Win-Ceramic Material Co. Ltd operates from No.22 Changguo Western Road in Zhangdian District, Zibo City, Shandong Province, China, placing it within one of China's densest clusters of industrial ceramic manufacturers. The company holds a Harbor trust tier designation on the trading platform, though its response rate is recorded at 0.00% with an average response time of zero hours, indicating either a new listing, limited platform engagement, or data capture issues rather than necessarily reflecting operational capacity. The supplier's specialisation in alumina ceramic rings for petroleum, chemical and environmental industries suggests vertical integration with local raw material suppliers and kilns in the Zibo region, which hosts hundreds of refractory and ceramic producers. No verified factory size, annual output figures, ISO certification numbers, or named client references appear in the available profile data.

The listing positions Zibo Win-Ceramic as a producer of inert alumina ceramic support media across the 90%-99% purity range, implying capability in both standard and high-purity ceramic formulation. Buyers should note that Shandong Province is a major export hub for industrial ceramics with established logistics corridors to Qingdao and Yantian ports, though the supplier does not specify preferred Incoterms, minimum order quantities, or lead times in the current data. The absence of response metrics suggests initial contact may require follow-up through alternative channels. Prospective importers should request factory audit documentation, specific alumina batch certificates, and crush strength test reports before committing to volume orders, as these quality verification steps are standard practice when sourcing engineered ceramics from first-time Chinese suppliers.
