DN200 * 200 mm height 250Y Structured Packing 304 in tube use
1. 250Y Structured Packing 304
One customer from Shandong customized this small piece of
structured packing, DN200 diameter by 200mm height of 250Y type.
She is going to use it in the tube to break the vortex.

3. Distillation Packing Factory
has years of engineering experience with a variety of structured
column packings in different industrial applications. Moreover, we
have frequent co-operations with famous universities and technical
engineering companies in China.
Resulting from these valuable assets, we have produced range of
structured packings suitable for engineering systems that provide
optimum column performance.
structured packing uses the industry standard corrugated perforated
and embossed sheet metal design to provide efficient vapour-liquid
contact. The style of the embossed surface has been optimised to
provide maximum wetability and numerous perforations enhance cross
mixing of the process fluids. Type Y has a crimp angle of 45° and
type X 30°. Suitable liquid irrigation range from below 0.5 up to
200 m3/m2.hr.
4. 250Y Structured Packing 304 History.
Structured packing was first introduced to the market in 20th century. Its distinct performance advantages became clear very
quickly and lead it to transform the mass transfer market after
then. It is now the preferred packing for many applications.
structured packing is formed from vertical sheets of corrugated
metal with the angle of the corrugations reversed in adjacent
sheets to form a very open structure with inclined flow channels.
To simplify installation, it is delivered in preformed segments
that are sized to fit through the vessel manways. A high surface
area will only provide efficient mass transfer if it is effectively
used to increase vapour-liquid contact. So a variety of surface
enhancements are employed to promote liquid spreading over the
packing surface. The low resistance to vapour flow together with
efficient use of available surface tends to give structured
packings significant performance advantages over random packings in
high vapour rate/low liquid rate systems.
SS304, SS316L, others as per order.
every year we manufacture and supply hundreds of cubic meters of
metal structured packing in different models. There are many
popular types and materials for option. Custom order is welcome,
too! We are happy to help with what you need!
