Abstract: An improved conveyor tube and distribution header for air conveyors such as air seeders serves to distribute seed and/or fertilizer products from the aircart to individual delivery tools via pneumatic conveyor tubes. The apparatus is adapted to achieve substantially even distribution of the materials being conveyed to each of the delivery tools. The apparatus includes a conveyor tube for conveying air-entrained material from a first location to a distribution head, which conveyor tube has an interior surface with a plurality of inwardly directed spaced apart projections which are disposed in spaced annular rows extending around the lengthwise axis of the tube for creating controlled turbulence in the flow of material. These projections are arranged in a particular manner to achieve the desired degree of turbulence.
