Product Description

As an advancement on the raschig ring, metal pall ring is a open-hole ring packing,, metal pall ring has similar cylindrical dimensions but has two rows of punched out holes, with fingers or webs turned into the centre of the cylinder, which significantly increases the performance of the packing, in terms of throughput, efficiency and pressure drop, better than raschig ring. By minimizing the number of contours and crevices that can cause liquid hold-up and potential entrainment, the metal pall ring geometry enables high gas and liquid transfer rates. The interior and exterior contacting surfaces of the metal pall ring provide for an effective distribution of liquids and gasses and resist plugging, fouling and nesting. metallic pall rings are available in a wide range of materials, such as carbon steel, stainless steel: SS304, 304L, SS400, 410,316, 316L etc.

 

Metal Pall Ring product model:

6mm(1/4"), 10mm(3/8"), 16mm(5/8"), 25mm (1") ,38mm(1.5"),50mm(2"),76mm(3")

Features of metal pall ring:

Capacity vs Pressure Drop: Metal pall ring  has high loading and throughput with low pressure drop character, and metal pall ring has good liquid and gas distribution and also high mass transfer efficiency.

Versatility: Metal pall ring can be easily wettabl, and has high resistance to fouling and high temperature.

Mechanical Strength: Metal pall ring’s high mechanically robust, lesser probability of breakage make it could be suitable for deeper beds.

Application of metal pall ring: 

Metal pall ring packing can be widely used Various separation and absorption applications at atmospheric pressure and under vacuum, where a low pressure drop is critical. metal pall ring can also applied for H2S, NH3 and SO2 absorption and strip, steam stripping, quench towers, direct contact cooling.
