Fast delivery 500Y metal plate structured packing 150mm to 8000mm
size
Structured packing provides a large surface area per unit volume,
which maximizes mass transfer performance and creates a lower
pressure drop than conventional distillation trays. By reducing the
pressure drop, structured packing increases energy efficiency.
Together with our structured packing, we use our own demister /
mist eliminators to maximize column performance.
Proven performance
Around the world, we have deployed our structured packing in
chemical processing, steel, gas-to- liquid (GTL), gasification and
a wide variety of other applications.
Compare: Packed columns offer multiple benefits
| Packed columns | Trayed columns |
| Lower pressure drop leads to significant power savings. (Greater
than 5% reduction in power is possible.) | Higher pressure drop, but shorter columns. |
| High turndown capability. (Down to 40% of design capacity is
possible.) | Limited turndown for efficient operation. (60-70% of design
capacity is typical.) |
| Enables pure argon production by distillation, therefore
eliminating need for a pure hydrogen source. | Can be used for high-pressure distillation. |

1 General Provisions
1.1 This standard specifies the requirements for marking,
specification and characteristics, materials, manufacturing
requirements, inspection and acceptance, marking, packaging,
storage and transportation of stainless steel orifice corrugated
packing products, as well as the calculation of characteristic
parameters of orifice corrugated packing.
1.2 The corrugated packing with stainless steel orifice plate is
suitable for gas-liquid mass transfer separation tower equipment,
and the applicable temperature of the packing is - 200 ~ 400 ℃.
1.3 The structured packing is suitable for the clean gas-liquid
system without solid particles or suspended solids or easy to self
assemble.
2. Reference standard: GB / T 4239 cold rolled stainless steel and
heat resistant steel strip
3.1 Mark
HG/T 21559.2—2005—P×××—×××
Standard No. - year No. - packing model - inner diameter of tower Φ
(mm)
For example, the inner diameter of packing tower is Φ 600mm, and
p250i type stainless steel orifice corrugated packing is used,
which is marked as follows: HG/T 21559.2—2005—P250I—600.
3.2 Specifications and characteristics
3.2.1 Stainless steel orifice corrugated packing is a number of
corrugated plates pressed from stainless steel strip, which are
vertically stacked and assembled into a disc-shaped structured
packing according to the requirements of a certain diameter. The
corrugations of the adjacent corrugated plates are inclined in the
opposite direction, and the corrugations of the upper and lower
adjacent packing plates are 90 ° crossed.
3.2.2 Before the corrugated plate is pressed, it is necessary to
punch holes on the plate in advance and press the fine grain, or
use the rolling grain equivalent to the fine grain.
3.2.3 Eight types of stainless steel orifice plate corrugated
packing are listed in the table. The characteristic parameters of
the type selection are the specific surface area of the packing and
the angle of the corrugation, which can be selected according to
the process design requirements.
