Metal Pall Ring
Metal pall ring is an important type of pall ring. Compared with plastic pall ring, the metal pall ring has better corrosion and rust resistance to be used in the extremely harsh environments. Metal pall ring is mainly made of carbon steel, galvanized steel, stainless steel and other materials. Stainless steel pall ring is the most popular and widely used type because of the best corrosion resistance and chemical stability performance.
Similar to the ceramic pall ring, there are two layer of windows on the cylinder wall. And each layer has five ligules, which is punched and bending inward the axe of ring.
