Metal structured packing is an industrial packing made by punching holes on the surface of metal sheets, rolling small and large waves, and then assembling them. It has the characteristics of low resistance, uniform gas and liquid distribution, large flow rate, high efficiency, strong anti-blocking ability, heat resistance, corrosion resistance, and good separation effect. According to the differences in wave shape and processing technology, it is classified into types such as wire mesh wave-shaped packing, stainless steel perforated plate wave-shaped packing, and perforated plate wave-shaped packing. Among them, the perforated plate wave-shaped packing exhibits excellent separation performance under negative pressure, normal pressure, and pressurized operation environments, and is widely used in precision separation in the fields of petroleum, chemical industry, and medicine.
The following is a comprehensive list of performance parameters for common regularized packing materials, for your reference:
