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 Metal Pall Ring Tower Packing Manufacturers, Factory

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 (FAQ)

1. What materials are available for Metal Pall Rings?

Metal Pall Rings are commonly manufactured using Stainless Steel (SS304, SS316, SS316L), Carbon Steel, and other specialty alloys to suit various chemical operating environments and anti-corrosion requirements.

2. How does the size and wall thickness affect performance?

Thicker wall specifications provide higher mechanical strength and weight load resistance, while ring size directly influences surface area, free volume, pressure drop, and mass transfer efficiency within the packed tower.

3. What packaging options are available for shipment?

Products are professionally packed based on volume and transport method, offering options including export carton boxes, heavy-duty jumbo bags, and fumigated wooden cases to guarantee safe transit.

4. What is the typical lead time for standard and custom orders?

Sample orders are dispatched immediately from existing stock. Standard orders (1 CBM to 20GP container) typically take 3 to 7 days, while larger volumes (40GP/40HQ) require approximately 14 to 20 days.

5. Can I order customized dimensions or materials?

Yes, customized manufacturing is allowed. We can supply tailored thickness, specific diameter dimensions, and designated metal alloy grades based on your project design requirements.

6. What is the Minimum Order Quantity (MOQ)?

The minimum order quantity for commercial batches is 1 CBM, while evaluation and quality test sample orders can be provided starting from under 5 pieces.
