The metal VSP ring — the inner arc ring, or Meller ring — is a metal packing shaped roughly like a garland: a ring whose wall is largely open, made up of arcs that curve inward rather than a solid tube. That open, curved wall is what gives the packing its character. It lets a large flow through at low resistance, keeps the void high, and, because the arcs are symmetric and the piece geometrically regular, it spreads gas and liquid evenly instead of letting them drift or channel. Being metal, it adds mechanical strength and corrosion resistance on top. The result is a packing that combines high capacity, high efficiency and even flow with durability.
What each characteristic gives you:
| Characteristic | What it gives |
|---|
| Large open area in the ring wall | Large flux and low gas resistance |
| High void fraction (93 to 95 percent) | High capacity and headroom before flooding |
| Symmetric arcs, uniform structure | Even distribution, so no bias or channelling |
| Smooth curved surfaces, no flat traps | Resists blocking and tends to self-clear |
| Metal construction | High mechanical strength and corrosion resistance |
That mix suits reaction and separation towers across petrochemical, fertilizer, chemical and environmental plants, where the packing increases the contact area between reactants and lifts both efficiency and product quality. It is made in Φ25, Φ38, Φ50 and Φ76 mm; the per-size surface area, void and packing factor are tabulated above. The Basic Info sheet supplied did not list the alloy or an HS code, so please confirm both — send us the tower and the medium and we will match the size and the grade.
