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.

China Metal Super Raschig Ring Tower Packing Factory, Factories

The design of the Super Raschig Ring offers an optimal solution to industry's demands for a modern heavy-duty packing. Unlike previous packing shapes, the Super Raschig Ring avoids the droplet formation which is such a frequent interference accompanying large gas loads. The Super Raschig Ring has a more than 30% greater load capacity, an almost 70% lower pressure drop and a mass transfer efficiency exceeding that of conventional metal packing by over 10%, them are widely used in packing towers in petrochemical industry, chemical fertilizer industry and environmental protection, etc. Metal raschig ring can be a variety of materials, such as carbon steel, stainless steel 304, 304L, 410, 316, 316L, etc. to choose from.

Frequently Asked Questions

What are the standard packaging options for Metal Super Raschig Rings?

Standard packaging options include carton boxes, jumbo bags, and wooden cases to ensure safe transport. Customized packing solutions are also available based on specific requirements.

What is the typical delivery lead time for orders?

Sample orders are usually dispatched from stock immediately. For regular bulk shipments, delivery typically takes 3 to 7 days for smaller orders (<25 CBM / Minimum 1 CBM), 14 days for a 40GP container, and up to 20 days for a 40HQ container.

What is the minimum order quantity (MOQ)?

The minimum order volume for formal orders is 1 CBM. For evaluation, testing, or quality inspection purposes, sample orders below 5 pieces can be arranged.

Are customized dimensions and specifications available?

Yes, custom manufacturing is fully supported. We can tailor the ring size, wall thickness, and specific metal alloys to meet your engineering and process requirements.

How does the sizing affect the surface area and void fraction?

Smaller ring sizes (e.g., 0.3" to 0.7") provide higher specific surface area (up to 315 m²/m³), optimizing mass transfer efficiency. Larger ring sizes (e.g., 1.5" to 3.5") offer lower pressure drop and higher free volume (up to 98.1%), enabling higher throughput capacities.
