SS316L 25mm Tower Random Packing Stainless Steel Metal Pall Ring
Product Introduction
Metal pall packing is made of carbon steel,stainless steel,
aluminum or other materials.
The product has features such as thin wall, heat resistant,high
free volume, high capacity, low resistance, high separation
efficiency and so on.
It is especially suitable for rectification towers under vacuum to
treat thermosensitive, decomposable, polymerizable or cokable
systems, so it is widely used in packing towers in petrochemical
industry, chemical fertilizer industry and environmental
protection, etc.
How to choose the best suitable size of Metal Pall Rings?
Here we have some reference data:

Attentions
The joint clearance of pall ring shall be less than 0.4mm for DN16,
DN25 and DN38mm, and less than 0.8mm for DN50 and DN76.
The upper and lower edges of the ring are not allowed to be
dislocated. The end cross section of the pall ring shall be
perpendicular to the axial center line and 90 degrees to the side.
There shall be no crack on the surface of packing ring and no burr
on the edge of packing.
The package material must be strong enough, to endure loading,
unloading and carrying for a few times. And it shall protect the
pall rings to reach destination safely. Rain proof and
moisture-proof measures shall be taken for metal pall rings during
transportation. The random tower packing stainless steel pall rings
shall be stored in a dry and non corrosive place. Do not store the
pall rings in broken packages.
In 1940s, a famous Gemeny company modified the raschig ring
greatly. In metal raschig rings, they open several windows on the
side wall with inward blades. Without increasing the surface area
of the packing, the flow of gas-liquid two-phase in the packing
layer is greatly improved, and the hydrodynamics and mass transfer
performance of the packing are improved.
