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 ).
