Metal Pall Ring with High Load Elasticity

Metal pall ring is a cylinder whose height is same as its diameter. It has both a unique multiple-blade design and several windows open on its surface to enlarge the internal surface area and promotes the fluid-air exchange. Metal pall ring is commonly made of stainless steel or carbon steel. Compared with plastic pall ring, metal pall ring packing has higher mechanical strength and better mass transfer performance. The five most popular nominal diameters of metal pall ring, widely applied to industrial manufacture, are DN 16, DN 25, DN 38, DN 50 and DN 76 mm.
