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.

Wholesale Metal Cascade Mini Ring Tower Packing Supplier, Quotes

Metal cascade-mini rings random tower packings, with one or two bevel edges in their sidepieces, are of more mechanical strength and better gas through capacity than pall rings. In random packed tower, most of the rings point contact (not linearity contact) to each other, contribute to the liquid film liquidity and mass transfer efficiency. Zhongtai's Metal cascade-mini rings are widely used in petroleum, chemicals, Chlor-Alkali and environmental industries.

Frequently Asked Questions (FAQ)

What materials are available for the Metal Cascade Mini Ring?

We supply metal cascade mini rings in carbon steel and various grades of stainless steel, including 304, 304L, 410, 316, and 316L. Other alloys can be accommodated upon request.

What makes the cascade mini ring design superior to standard random packing rings?

Its beveled edges allow the rings to orient predominantly along their vertical axis, ensuring a lower pressure drop, reduced fouling tendency, and significantly higher liquid-gas mass transfer efficiency.

Can wall thickness and dimensions be customized?

Yes, while our standard specifications cover 0P through 5P and various bevel types, customized wall thicknesses, diameter sizes, and dimensions are available to match your specific tower design.

What is the minimum order quantity (MOQ) and sample lead time?

Our standard minimum order is 1 CBM. For small sample orders (< 5 pcs), samples can be dispatched directly from stock.

What are the common packaging methods for export?

Depending on the order volume and transport method, products are packed securely in standard carton boxes, jumbo bags, or export-grade wooden cases to ensure safe transit.
