Metal bulk packing, due to its thin processing wall, high porosity, large flow rate and low resistance, as well as heat resistance, corrosion resistance and high separation efficiency, is particularly suitable for vacuum distillation columns. It can process heat-sensitive, easily decomposed, easily polymerized and easy to carbonize materials, so it is widely used in petrochemical, chemical, fertilizer, environmental protection and other industries.

Metal loose packing mainly has conjugate ring, 84 inner arc ring, rectangular saddle ring, double arc ring, flat ring, step ring, Raschig ring, Bauer ring and other specifications.
