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.

Frequently Asked Questions

What are the available material options for Metal Raschig Rings?

Metal Raschig Rings are primarily fabricated in stainless steel grades such as 304, 304L, 316, and 316L, as well as carbon steel and other corrosion-resistant alloys tailored to specific industrial requirements.

What is the minimum order quantity (MOQ)?

The minimum standard order volume is 1 CBM. For quality evaluations or initial testing, sample requests of fewer than 5 pieces are available directly from stock.

Can sizes and wall thicknesses be customized?

Yes, custom manufacturing is permitted. We can produce rings with distinct diameters, lengths, and wall thicknesses to fulfill specific process engineering designs.

What packaging methods are provided for export?

We offer versatile packaging options designed for sea and air freight safety, including sturdy carton boxes, bulk jumbo bags, and reinforced wooden cases.

What is the typical shipping lead time for bulk orders?

Lead times vary according to volume: a standard 20GP container generally ships within 7 days, a 40GP in approximately 14 days, and a 40HQ in about 20 days.

Where are Metal Raschig Rings commonly applied?

They are widely utilized in mass transfer towers across the chemical, petrochemical, and environmental sectors, including absorption towers, distillation columns, and gas stripping systems.
