Import 50x44mm Alumina Ceramic Six Wing Ring — Buy in wholesale FOB from Supplier in China

The 50x44mm Alumina Ceramic Six Wing Ring from Zibo Win-Ceramic Material Co. Ltd features a taller aspect ratio than the 40mm height variant, with dimensions of 50mm outer diameter by 44mm height. This geometry alters the packing factor and pressure drop characteristics, making it suited to applications where slightly higher mass-transfer efficiency per theoretical stage is prioritised over maximum throughput capacity. The supplier specifies construction from high-purity alumina, though the exact percentage is not stated in the source data and must be confirmed directly.

The additional 4mm in height increases the individual piece surface area while maintaining the same nominal diameter, which shifts the specific surface area to void fraction ratio toward enhanced contacting efficiency. Six-wing rings in this size class are typically manufactured with wall thickness of 5-8mm and wing width of 10-15mm, though these parameters vary by producer and mold wear condition. The taller profile may exhibit slightly greater fragility during column loading and requires more careful dumping procedures to prevent edge chipping that creates fines and increases pressure drop. Standard industry practice for 50mm nominal tower packing is to specify dimensional tolerance of ±2mm on diameter and ±2mm on height for process guarantee purposes.

This _(heightened)_ ring configuration finds application in heat exchangers, catalytic support beds, and reactor internals where the extended surface promotes thermal uniformity and reactant distribution. Aerospace and automotive thermal management systems, as referenced by the supplier, represent niche applications where alumina ceramic structural elements must withstand thermal cycling and mechanical vibration. Buyers should clarify with Zibo Win-Ceramic Material Co. Ltd whether the stated high-temperature resistance and lightweight claims correspond to this specific 50x44mm geometry or represent generic alumina ceramic properties, and request comparative test data against standard of the art alternatives such as structured sheet metal or modern random packing geometries.

Zibo Win-Ceramic Material Co. Ltd maintains its registered address at No.22, Changguo Western Road, Zhangdian District, Zibo, Shandong, 255000, China. The company's location in Zibo provides access to bauxite-derived alumina feedstocks and established ceramic engineering infrastructure within China's largest ceramic production cluster. The supplier's profile indicates a harbour trust tier with zero recorded responses and zero average response hours, which prospective buyers should interpret as an absence of demonstrated communication history rather than necessarily negative trading record.

No information is provided regarding the company's establishment date, legal entity type, production capacity, number of employees, annual turnover, or export licence status. The source description contains references to ISO and CE certifications without identifying the certifying bodies, scope of certification, or validity periods. Buyers must independently verify factory existence through business registration checks, request current certification documents with accreditation marks, and consider engaging third-party inspection services before releasing substantial advance payments. The absence of disclosed clientele or project references means due diligence burden falls entirely on the prospective importer.
