Porcelain Pall Rings Description
Porcelain Pall Rings are cylindrical packing materials made from high-quality porcelain, known for their excellent thermal and chemical resistance. Their unique design with inward and outward protrusions creates a large surface area for gas-liquid contact, promoting efficient mass transfer. They are popular in petrochemicals, pharmaceuticals, chemicals, and environmental protection industries.
