Abstract
A pipe part (100) for conveying a solid particulate material, comprising an outer tubular element (1) stretching along a longitudinal axis (A) and having first (9) and second (12) sections axially displaced from each other. An inner tubular element (20) is disposable inside the outer tubular element (1) and adapted for longitudinally conveying the solid particulate material from one end to another end. The inner tubular element (20) comprises an aeration-fluid-permeable wall part (23), and is sealingly connected with—and flexibly supported by—the first and second sections (9,12) to form an aeration fluid distribution chamber (40) between the first and second sections (9,12) and the inner (20) and outer (1) tubular elements. The aeration fluid distribution chamber (40) is provided with an aeration fluid inlet (15) to define an aeration fluid flow path (19) between the aeration fluid inlet (15) through the aeration-fluid-permeable wall part (23) via the aeration fluid distribution chamber (40).
