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 304 316 Stainless Steel Metal Teller Rosette Ring Flower Shape Tower Packing 25mm 38mm 50mm Random Column Packing Manufacturer Supplier

Product Overview

Metal Teller Rosette Ring is a high-efficiency flower-shaped metal random packing, specially designed for industrial tower mass transfer and purification systems.

Its unique multi-petal rosette/flower-shaped structure eliminates dead zones inside the tower, ensures uniform gas-liquid contact in all directions, and effectively avoids stacking overlap and channeling problems.

Made of high wear-resistant 304 & 316 stainless steel, it offers excellent corrosion resistance, high mechanical strength and stable performance even in harsh environments with scaling or erosion.

With core advantages of large voidage, low pressure drop and high mass transfer efficiency, it is widely used in desulfurization towers, waste gas purification, chemical absorption and petrochemical refining systems.

Frequently Asked Questions (FAQ)

Q What are the main advantages of the Metal Teller Rosette Ring?

It provides a unique multi-petal configuration that ensures large voidage, extremely low pressure drop, uniform gas-liquid contact, and eliminates dead zones or liquid channeling inside packed columns.

Q Which materials are used for manufacturing Metal Teller Rosette Rings?

They are commonly made of high-quality stainless steel grades such as SS304 and SS316, ensuring superior corrosion resistance, high tensile strength, and long operational life under harsh conditions.

Q What industries and applications utilize this random packing?

It is extensively used in desulfurization towers, industrial waste gas purification, chemical absorption units, acid scrubbing, and petrochemical refining systems.

Q How does the rosette design prevent tower clogging and dead zones?

The geometric open structure prevents nesting and stacking overlap among rings, maximizing free volume (up to 97.3%) and allowing continuous liquid redistribution without sediment blockage.

Q What standard sizes are available for Metal Teller Rosette Rings?

Standard sizes include 2 inches (50×25×0.8 mm), 3 inches (75×75×1.0 mm), and 4 inches (100×45×1.2 mm), each engineered to suit specific tower diameters and hydraulic load capacities.
