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.
Compared with pall ring, the fluxes are increased 15-30% and the pressure drop is reduced 20%–30%.
