Which alumina grade of inert ceramic ball should I choose for catalyst bed support?

Standard 17–23% Al2O3 inert balls suit most hydrotreating and reforming catalyst supports. Choose 23–30% for higher crush strength, and 99% alumina where high-temperature steam could cause silica leaching that would poison downstream catalysts.

What information do you need to recommend tower packing?

Please share the tower diameter and bed height, the service (distillation, absorption, stripping or scrubbing), the medium and its corrosivity, operating temperature and pressure, and any pressure-drop or capacity targets. Our engineers then propose packing type, material and size.

Can I receive samples and technical data sheets before ordering?

Yes. Samples of standard sizes and technical data sheets covering chemical composition, bulk density, crush strength and other key properties can be provided for evaluation before a production order.

How are ceramic and metal packing products packed for export?

Depending on product and volume, we use cartons, jumbo bags, plastic drums or wooden cases on fumigation-free or fumigated pallets, with clear marking for each size and batch to simplify site receiving.

Where is Zhongtai located and can buyers visit the factory?

We are based in Pingxiang, Jiangxi Province, a recognized Chinese hub for industrial ceramics and chemical packing. Buyers and third-party inspectors are welcome to visit; Korean customers audited our ceramic production in July 2018.
