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.

Product Description

The Metal Super Raschig Ring, widely known as Raschig Super-Ring (RSR) or Conjugate Ring, represents the fourth generation of random tower packing. It combines the advantages of ring and saddle packings, engineered to deliver an optimal solution for high-performance, heavy-duty applications in the petrochemical, fertilizer, and environmental protection industries.

A key differentiator is its double-layer conjugated curved rib structure with alternating wave swings, which promotes turbulent film-type flow and effectively prevents droplet formation that typically interferes with large gas loads. Performance data shows it offers over 30% greater load capacity, almost 70% lower pressure drop, and more than 10% higher mass transfer efficiency compared to conventional packings.

Product Highlights

Exceptional Capacity & Efficiency: Over 30% greater load capacity and more than 10% higher mass transfer efficiency compared to conventional metal packings.
Ultra-Low Pressure Drop: Special alternating wave structure reduces resistance by almost 70%, significantly cutting energy consumption and operating costs.
Semi-Structured Packing Behavior: Unique alternating wave swings and open geometry promote homogeneous liquid film flow, preventing channeling and minimizing redistributor needs.
Anti-Fouling & Clogging Resistance: Smooth, open geometry effectively avoids droplet formation and is suitable for handling liquids contaminated with solids.
Superior Mechanical Strength: Robust double-layer design ensures high crushing strength and long-term structural stability under heavy loads.
High-Performance Material Options: Manufactured in 304, 316L, and specialty alloys including titanium and nickel for superior corrosion and heat resistance in aggressive environments.
