Big size metal pall ring 3 inch 76mm custom material random packing

 

The metal pall ring random packing was developed by BASF company in 1940s on the basis of raschig ring. It is made of sheet metal by punching and rolling. Two rows of window holes with tongue leaves extending inside are opened on the ring wall. Each row of window has five tongue leaves bending into the ring, pointing to the ring center, almost connecting at the center, and the upper and lower layers of window holes are staggered with each other. Generally, the total area of the opening is about 35% of the whole ring area. As a result of opening windows on the ring wall, the distribution of gas and liquid in the packing bed and the mass transfer performance are greatly improved compared with that in the raschig ring. People have made plenty of study of its performance, so pall ring is still one of the main random packing used at present.​

Pall ring takes an advantage that as random packing being mass produced with standard elements, the delivery periods are relatively short from storage. Because the pall ring can be used in many applications regardless the size of columns, we hold a stock of most types of random packings for fast delivery.

Random column packing is packaged and shipped by volume. A volume adjustment factor must be applied to the calculated column. Geometric volume to estimate the shipping volume required to properly fill a packed bed to account for edge and settling effects. The volume adjustment factor depends upon the packing shape and size and the bed diameter.

 

Hualai pall rings are available in several sizes as indicated on our design sheets to suit most commercial applications. They range in size from 10mm to 76mm or equivalent. It is an essentially a design consideration in specifying a packing size based on capacity and efficiency requirements. The nominal packing size specified should however not be greater than 1/10th of the column diameter.

 

The packing is usually specified in the lowest cost material of manufacture that will satisfy temperature and corrosion requirements. Some of the most common materials listed in order of relative cost are:

Polypropylene (mainly aqueous systems up to 100 deg. C)

Carbon steel (non-corrosive hydrocarbon systems)

Ceramic (sulphuric acid & nitric acid absorbers)

Stainless steels (most hydrocarbon systems)

PVDF, PFA (corrosive aqueous systems up to 150 deg. C)

PVC / C-PVC (corrosive aqueous systems up to 90 deg. C)
