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

Products Description

Metal Pall Ring packing use of sheet metal by punching in the ring out of the wall with two rows of fenestrae with leaves. Fenestrae in each row there are five tongue leaves, each leaf tongue ring, point to ring heart, almost in the center up, the location of the upper and lower levels staggered fenestrae, the general opening of the ring a total area of about 35% of wall area around Pall Ring packing as a result of in-the-loop to open a lot of window walls, making the tower the gas and liquid can move freely through the window, the current Central fill Powell was used by one of the main ring packing.

Metal Pall Ring will have 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 available materials for Metal Pall Rings?

Metal Pall Rings can be manufactured in a variety of materials including Carbon Steel, Stainless Steel 304, Stainless Steel 304L, Stainless Steel 410, Stainless Steel 316, and Stainless Steel 316L depending on operating conditions and corrosive requirements.

How does the open-wall structure benefit column performance?

The cylinder wall features punched fenestrae with internal tongue leaves, yielding roughly a 35% total opening area. This configuration allows internal gas and liquid phases to flow freely through the ring windows, significantly lowering pressure drops and preventing liquid pooling.

What standard sizes are available for Metal Pall Rings?

They are available in imperial and metric dimensions ranging from 1/4" (6×6 mm), 3/8" (10×10 mm), 1/2" (13×13 mm), 5/8" (16×16 mm), 1" (25×25 mm), 1.5" (38×38 mm), 2" (50×50 mm), 3" (76×76 mm), to 3.5" (89×89 mm), with various wall thicknesses.

What are the primary applications of Metal Pall Rings?

Metal Pall Rings are widely utilized in mass transfer absorption, separation, and stripping towers throughout the chemical, petrochemical, and environmental protection industries.

Can Metal Pall Rings be customized in non-standard dimensions?

Yes, customized thicknesses, special metal alloys, and unique specifications can be accommodated according to project designs and processing procedures.
