鈥籓ther specifications are available upon request.
*Metal random tower packings are made of materials like carbon steel, stainless steel (304, 304L, 410, 316, 316L, etc) and Aluminum alloy, etc. The products have feature such as thin wall, heat resistant, high void ratio, high capacity, low resistance, high separation efficiency and so on. Them are especially suitable for rectification towers under vacuum to treat thermo sensitive, decomposable, polymerizable or cokable systems, so them are widely used in packing towers in petrochemical industry, chemical fertilizer industry and environmental protection, etc.*
