Seven Ring, 220±0.5 mm

Due to Ceramic Corrugated plate packing's weight, which is very heavy and that is why easy broken, in the end of 1980's the scientists have changed clay composition to produce light porcelain packing. This packing is widely used in the process of cooking, desulfurization, benzene washing, naphthalene and ammonia sulfuric acid drying, chemical fertilizer hot water saturation tower, electric power plant tricking water cooling tower, absorbing tower and etc. It is characterized by high temperature sweeping, low specific gravity, low resistance, large mass transfer coefficient, good absorption, anti-aging, strong corrosion resistance, long life, usually without overhauling.
