SS304 SS316L Pall Ring Various Sizes Similar Cylindrical Dimensions

SS304 SS316L Pall Ring Various Sizes Similar Cylindrical Dimensions

As an improvement of raschig ring, the pall ring has similar cylindrical dimensions. But the pall ring has two rows of punched holes with tongues turned into the center of the cylinder, which significantly increases the performance of the pall ring packing, in terms of capacity, efficiency and pressure drop.

We are able to offer our Pall Rings in a variety of materials such as grade 304, 316, or 430 Stainless Steel, Carbon Steel, Copper or special alloys.
