has a dozen number of machines for column internal corrugated wire mesh packing. The material we have includes SS304, SS316L, Titanium, Duplex 2205, copper, etc. Other materials can be negociated when need.
The mass transfer efficiency of wire mesh corrugated packing is directly determined by its specific surface area. According to the specific surface area, it can be divided into 250 (AX), 500(BX) and 700(CY) types. As the corrugated metal mesh filler belongs to the type of liquid membrane mass transfer, opening holes on corrugated filler sheet or making double-layer wire mesh filler to strengthen the uniform distribution of liquid on the corrugated wire mesh sheet, especially in low spray density, whether to ensure the uniform distribution of liquid on the wire mesh sheet is the key to maintain high separation efficiency.

Note:
1. The data are based on 0.12mm wire, stainless steel material. Applicable temperature (-200—400)℃. 0.15mm and 0.17mm wire are also available.
2. Metal wire mesh corrugated packing is suitable for clean gas-liquid system without solid particles or suspended solids or not easy to self-assemble.
