An apparatus is disclosed for centering a reinforcing mesh which is in a pipe or conduit form for manufacturing reinforced concrete pipe or conduit. In order to automatically center the reinforcing mesh in a simple and reliable fashion, a plurality of mesh centering units are provided which are distributed at spaced intervals around the perimeter of the form. Each of these units comprises at least one radially outwardly extending member which penetrates through a receiving slot into the form to a depth which is adjustable depending on the external diameter of the reinforcing mesh. When the concrete introduced into the form is compacted, the member can be retracted to an inactive position from the operating position, in which it biases against the centered mesh.
