Metallic VSP ring, also called inner arc ring, very special ring, is made of carbon steel, stainless steel, titanium alloy, aluminum alloy, copper alloy and stainless steel materials. Metallic VSP rings has reasonable geometric symmetry, which the inner arc are folded evenly along the axial direction and replaced alternated arranged. This design contributes a continuous surface for extremely high voidage and evenly distribution.
Metal VSP ring has the features of thin wall, large void ratio, high flowing, capacity, low pressure drop and good separation efficiency. So its application range is very wide, for drying, absorbing, cooling and regenerating tower in chemical metallurgic, coal gas and air separation industry.
