Metal Random Packing

Metal random packing is made using carbon steel, stainless steel and other metals as raw material. Metal random tower packing offered by Hualian is characterized by thin thickness, thermal resistance, high porosity, large flux, small resistance and high separation efficiency.

Metal random packing is an ideal choice for the vacuum distillation of materials which are thermal sensitive and easy to decompose, polymerize and carbonize. A wide application of metal random packing is found in industries as petrochemical engineering, chemical fertilizer and environmental protection.
