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.

Metal super mini ring (SMR or named flat ring) random tower packing, is especially suitable for relative flow movement of liquid-liquid phase, and lessens agglomeration of dispersed droplet cluster. The mode of symmetrical inflexed arced fins will have good impact on the flowing homogeneity of liquid, promote the cyclic process of dispersion, convergence and redispersion of droplet cluster, effectively reduce the axial back-mixing of packing layer, and improve the mass transfer efficiency of liquid to liquid. Therefore, the packing will obtain excellent technological and economical effects in extraction process of liquid-liquid mass transfer.

Frequently Asked Questions

Q What materials are available for the metal flat ring?

Standard technical specifications are listed based on stainless steel 304 (SS304). Custom material options and specific thickness adjustments can also be manufactured upon request.

Q What is the minimum order quantity (MOQ)?

The minimum order quantity for standard production runs is 1 CBM. For evaluation, testing, or trials, sample orders under 5 pieces are supported.

Q How long does delivery take for different order volumes?

Samples are readily dispatched from existing stock. Minimum orders (1 CBM) take around 3 days, regular orders under 25 CBM take 7 days, and full container shipments require 7 to 20 days depending on container capacity (20GP, 40GP, or 40HQ).

Q What packaging solutions are provided for overseas transit?

Orders are typically packed using heavy-duty carton boxes, high-capacity jumbo bags, or sturdy wooden cases to prevent distortion and ensure safe delivery during transit.

Q Can dimensions and thicknesses be customized?

Yes, customized production is available. Dimensions, plate thickness, and packaging types can be tailored to meet your particular operational criteria.
