1. Metal Pall Ring Basic Introduction:
Pall ring is a new type of filler improved on Raschig ring.
Compared with the later, pall ring has improved the liquid
distribution of filler layer greatly, with open windows on ring
sidewall. Therefore it has productivity, low resistance, operating
flexible and higher efficiency. Pall ring is widely applied to
industry. It is still one of major annular fillers that has been
adopted.

3. Metal Pall Rings Advantage:
Metal Pall Ring 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.
A contingency allowance for installation losses, typically around
5%, should be added to the shipping volume calculated above.
Strict conformity with recommended installation procedure is
necessary to ensure consistent duplication of design performance.
Installation techniques that result in installation crew walking on
or raking the packing must never be employed. Incorrect
installation procedures can result in substantial packing shortfall
(i.e. installed volume not sufficient for the required bed height
resulting in performance losses).
4. Metal Pall Rings Sales Case:
I have a korean customer named Mr. J. He works as a chemical
engineer in a corporation laboratory. Last time he contacted me to
see if we could provide 16mm pall rings in SS316, with certificates
for the material. Also he need the column random packing in a
hurry. Surely no problem! We have stock of such packing for
immediate delivery. It is convenient to send the pall rings by
SF-express to Republic of Korea, especially when the customers have
a SF account.
This page is about standard specifications of pall rings, 16mm,
25mm, 38mm, 50mm, 76mm in diameter and hieght. Here also introduced
the structure size, manufacturing, inspecting, packaging and
shipping.
The working temperature of SS pall rings is recommended to be under
400 centigrade.
The pall rings are in cylinder shape, with equal height and
diameter, and some windows on the side.
