Structured Packing - Metal, Plastic and Ceramic Types

The structured packing is made of several packings with different geometrical shape and corrugation angle. According to different corrugation angle, it can be divided into X type and Y type. The X type stands for the 30° angle, and the Y type stands for the 45° angle. X type structured packing has small pressure drop and the Y type structured packing has better mass transfer property.

The structured packing can be divided into metal structured packing, ceramic structured packing and plastic structured packing.

Metal Structured Packing

Metal structured packing can be made of various metal materials, such as low carbon steel, stainless steel, Monel, Ti and others. The stainless steel structured packing is the most widely used because of the excellent corrosion and rust resistance and durable properties. Metal structured packing has different packing types, which can be divided into wire gauze structured packing and perforated plate structured packing.

Wire gauze structured packing

Wire gauze structured packing is made of various metal wires, such as stainless steel wire, monel wire, copper wire and then woven into wire gauze. Wire gauze structured packing has low pressure drop, high separating efficiency, it is the most widely used type among all metal structured packing. It is suitable for precise distillation and vacuum distillation devices.
