The classification of centrifugal casting pipeCentrifugal casting pipe according to the characteristics of can be divided into water-cooled metal mold casting, centrifugal casting pipe, coating metal mold centrifugal cast pipe, resin sand lined centrifugal cast pipe, mould centrifugal (obsolete).Water-cooled metal mold centrifugal casting pipeWater-cooled metal mold centrifugal casting tube is also called the ward centrifugal method and its structure characteristic is to use an ever-flowing trough, pouring can be pouring trough mobile, mobile, also can be cast with special water-cooling device structure is complex, high cost.In addition, because the water chilling effect, often appears white cast pipe, need heat treatment, casting pipe production efficiency is high, generally used for mass production of small and medium-sized ball iron pipe diameter.
