Packing standard no. : HG/T21559.2-2005
Extruded hole sheet metal,The corrugated packing of stainless steel orifice plate has an opening rate of 12.6% and an aperture of 4mm.
Corrugated packing of metal 316L hole plate: it is a regular packing assembled after punching the surface of metal sheet, rolling small lines and large ripples. It has the characteristics of small resistance, uniform gas-liquid distribution and large flux, and no obvious amplification effect. It is used in negative pressure, atmospheric pressure and pressure operation.
Corrugated packing is a kind of general structured packing, which belongs to most of the structured packing used in industry. Corrugated packing is a disc packing composed of many corrugated thin plates. It has compact structure and regular arrangement. Its specific surface area can be adjusted by the shape of corrugated structure. Corrugated and tower axis has 30 ° and 45 ° inclination of the main two kinds, each plate of vertical mounted on the tower packing, assembly of adjacent two corrugated plate reverse fold depend, alternating between adjacent two sets of packing 90 °, the perpendicular arrangement make updrafts changing direction, are constantly falling liquid distribution, fully mixing of fluid in tower, so the mass transfer.
Packing tower is an important gas-liquid mass transfer equipment in chemical separation process. Packing is installed in the packed tower, is the core component of the packed tower, it provides gas-liquid heat transfer, mass transfer contact surface, is used in oil refining, petrochemical, fine chemical, food, medicine and environmental protection and other chemical fields. Corrugated packing is a common and widely used chemical packing.
Pore plate corrugated packing surface pressurized pattern, enhance the wettability of packing, improve the specific surface area utilization rate of packing, promote the continuous renewal of vapor liquid contact surface, improve the mass transfer efficiency.

production of metal structured packing: stainless steel corrugated plate packing, metal mesh corrugated packing, stainless steel 316L mesh corrugated packing, stainless steel piercing corrugated packing, metal pipe packing, stainless steel inclined plate packing, etc.
the production of major metal filler for carbon steel, stainless steel, aluminum alloy, titanium and special alloy material as raw material to make a molding: it has a thin wall, qualitative light, heat and cold resistance, large void ratio, large flux, lower pressure drop, small resistance, good separation effect and the advantages of long service life, can be used under high temperature and high pressure, high impact strength.
Metal filler production raw material carbon steel filler cost is low, and has good appearance wettability, for no corrosion or low corrosion system should be given priority to use, but if there is corrosion in the place to use carbon steel may rust; Stainless steel packing is strong, generally can withstand the corrosion of rare things except Cl -, but its cost is higher but it has good use effect; Titanium, special alloy steel and other materials made of filler cost is very high, generally only in some corrosive system under the use.
The compressive strength of stainless steel packing is much higher than that of plastic and ceramic packing. The pressure resistance of the packing is the ability to resist plastic deformation at a certain temperature. It is not only related to the material of filler, but also has a great relationship with its structure size and processing technology. Chemical composition, heat treatment, grain size, metallographic structure and other mechanical properties are the main factors affecting the impact properties of metals. For carbon steel, the strength and hardness increase with the increase of carbon content, while the plasticity and impact value decrease.
Metal fillers are worse than plastic and ceramic fillers. It is easy to be corroded by water, atmosphere and various organic or inorganic solvents, so its use is limited to a certain extent. And metal fillers are expensive compared to ceramic and plastic fillers.
