The Center of a reducer circle ends which in a straight line is named as Concentric reducer. Usually reduced diameter forming process is pressed, compressed, or constricted diameter expanding compressed and reduced diameter together. Certain specifications reducers press molding may be employed. Common material in production WP304/304l/316/316L
