Ss304 Metal VSP Ring(25mm 38mm 50mm 76mm)

Metal VSP Ring (Vertical Spiral Partition Ring), also known globally as Mella Ring, is a high-efficiency random packing widely used in chemical and petrochemical industries. It is designed with a unique spiral structure that provides uniform geometric symmetry, high voidage, and excellent liquid distribution. Compared with traditional metal Pall Ring, Metal VSP Ring offers 15–30% higher liquid and gas throughput, while reducing pressure drop by 20–30%.

Made from high-quality stainless steel, carbon steel, or aluminum alloy, Metal VSP Ring has thin walls, strong mechanical strength, high heat resistance, and superior corrosion resistance. This special packing is particularly effective for processes that require high capacity, low resistance, and excellent separation efficiency.

Features of Metal VSP Ring

• Available materials: carbon steel, SS304, SS304L, SS316, SS316L, SS410, aluminum alloy.
• High crushing strength and easy installation.
• Excellent temperature resistance for harsh working conditions.
• High flooding point and low wetting point for efficient operation.
• Large free volume and high separation efficiency.

These features make Metal VSP Ring ideal for both standard and demanding chemical applications.

Specification & Technical Performance

The structure of Metal VSP Ring consists of evenly folded inner arcs arranged alternately along the axial direction. This unique geometry increases the contact area between liquid and gas, ensuring better mass transfer efficiency.
