What is a corrugated packing?

As the name suggests, it involves stamping thin sheets into a wavy shape and then making holes in them； The wire mesh corrugated filler is made by giving the wire mesh a corrugated shape

Metal perforated plate corrugated packing is made by drilling holes in metal sheets, rolling out small ridges and large corrugations, and then assembling them. It features low resistance, uniform gas-liquid distribution, high efficiency, large flow capacity, and no significant amplification effect, and is used in negative pressure, normal pressure, and pressurized operations. The improvement in plate towers using metal perforated corrugated packing is particularly significant. The tower diameter range for processing fillers is from φ150mm to over 12,000mm. Metal wire mesh packing is a highly efficient packing widely used around the world today; it consists of disc-shaped packs made up of several parallel rows of metal corrugated mesh sheets. It has a large specific surface area, high porosity, and low weight ； The gas-phase path has a small, regular inclination and low pressure ； It features good radial diffusion and sufficient gas contact.

In simple terms, it’s a type of structured packing

For this, I suggest you search for images online to take a look; it will be easy to understand once you do. . Plate corrugations are made from thin plates, while mesh corrugations are made from mesh. Anyway, my research topic involves studying the properties of structured fillers: lol

Orifice plate corrugation is a technique in which metal sheets are perforated, pressed into patterns, folded into corrugations, and then assembled together

Both plate corrugated packing and wire mesh corrugated packing belong to structured packing, and can be classified into metal and non-metal types based on their material. The manufacturing processes include: sheet preparation, punching, embossing, corrugating, etc.

　 Metal wire mesh corrugated packing is the main type of mesh corrugated packing, and it is made of metal wire mesh. The wire mesh corrugated packing has a low pressure drop and high separation efficiency; it is particularly suitable for precision distillation and vacuum distillation units, offering an effective method for the distillation of difficult-to-separate systems and heat-sensitive substances. Despite its high cost, it is widely used due to its excellent performance. Metal plate corrugated packing is a major type of plate corrugated packing. The corrugated plates of this filler are stamped with numerous small holes of about 5 mm in diameter, which help to roughly distribute the liquid across the plates and enhance lateral mixing. Fine grooves are rolled onto the corrugated sheet, which helps to distribute the liquid evenly across the sheet and improves surface wetting properties. Metallic perforated corrugated packing has high strength and excellent corrosion resistance, making it particularly suitable for large-diameter towers and applications with high gas-liquid loads. The advantages of corrugated packing include a compact structure, low resistance, high mass transfer efficiency, large processing capacity, and a large specific surface area (common values include 125, 150, 250, 350, 500, 700, etc.). The disadvantage of corrugated packing is that it is not suitable for handling materials with high viscosity, those that tend to polymerize, or those containing suspended solids. It is also difficult to load and unload, as well as to clean, and its cost is high. Last edited by Chuangxin Packing on 2009-3-13 14:26.]

Metal perforated corrugated packing is one of the most widely used structured packings. It consists of packing discs made up of metal sheets pressed into rows of corrugations with inclined teeth; the corrugations are inclined at 30 degrees or 45 degrees relative to the axis, and small holes can be made in the sheets to facilitate the dispersion and lateral mixing of the liquid. Features: reduced packing layer pressure, high flow rate, low resistance ； Even gas-liquid distribution and high mass transfer efficiency ； It has high operational flexibility, and the amplification effect is not significant. Application range: Suitable for operation under negative pressure, normal pressure, and positive pressure; it is particularly appropriate for the separation of heat-sensitive substances and high-purity media. It yields significant improvements when used to modify plate towers. Metal perforated plate corrugated packing models: 125Y, 250Y, 350Y, 500Y, 700Y, 125X, 250X, 350X

Plate corrugations are made of thin steel plates, while screen fillers are made of screens.
