Professional Supplier for Heat Exchanger & Pressure Vessel

Metal Pall ring is one of the most common and well-known packing. Metal Pall Ring is an industry standard design media developed from the Raschig Ring and is used widely in all variety of applications. By minimizing the number of contours and crevices that can cause liquid hold-up and potential entrainment, the metal pall ring’s geometry enables high gas and liquid transfer rates.

 
The opened cylinder walls and inward bent ligule of the Metal pall Ring allow greater capacity and lower pressure drop than standard cylindrical rings. This open ring design also maintains an efficient distribution and resists wall-channeling tendencies. The interior and exterior contacting surfaces of the Metal pall ring provide an effective distribution of liquids and gasses and resist plugging, fouling and nesting.
 
Metal pall rings are available in a wide range of materials such as SS 304, SS 316 , SS 316 L.
