Product Description

Metal Pall Ring: Technical Overview and Applications
1. Introduction
The Metal Pall Ring is a high-efficiency random packing material developed by BASF (Germany) in the 1940s as an improved version of the Raschig ring. It is manufactured by stamping metal sheets (stainless steel or carbon steel) and features a unique window-hole design with inward-bent tongues, enhancing gas-liquid contact and mass transfer efficiency.
 
2. Key Features & Advantages
(1) Structural Design
Two rows of staggered window holes (≈35% open area) with inward-extending tongues → improves fluid distribution.
Lower pressure drop (50-70% reduction) vs. Raschig rings.
Higher processing capacity (50-100% increase) due to optimized flow dynamics.
(2) Material & Sizes
Materials: Stainless steel (304, 316L, 321) & carbon steel.
Size range: 16×16×0.3mm to 100×100×1.0mm (customizable).
