Definition and structural characteristics of pall ring packing

Definition:

pall ring packing is an improved packing with two rows of rectangular windows on the side wall of the annular packing. The window blades are bent into the center of the ring and arranged in a staggered manner. This design is intended to optimize gas-liquid contact and improve mass transfer efficiency.

Structural advantages:

Open hole design: rectangular windows are opened on the ring wall, which increases the gas-liquid contact area and promotes the rotation and mixing of the fluid.

Low resistance: The larger porosity and optimized fluid channel design significantly reduce the pressure drop.

Various materials: including metals (such as 304/316 stainless steel), ceramics and plastics (such as PP, PVDF), which can meet the needs of different working conditions.
