<p>A channel element in material conveyor piping, said element comprising a wall and at least two junctions for connecting the channel element to the piping, as well as a channel (K) left inside the wall. The wall of the channel element (1) is made of plate elements (2, 2', 3, 4) and interconnected as a box-type structure; and in order to improve wear resistance, at least one wall (3) of the channel element (1, 20, 40), or part of said wall, is arranged to be thicker and/or made of a better wear resistant material than at least one other wall in the material conveyor piping.</p> |
