Abstract

A process and a device for centring a tubular piece 14 or for fastening the same by means of a mandrel 16, which mandrel has wedge-shaped wing elements 30, which are arranged radially between end plates 26, 28 and slide along the end plates, and a conical middle part 38, which is movable in the direction of the axis of the mandrel. The diameter of the mandrel is adjusted, in accordance with the diameter of the piece 14 to be treated, by moving the wing elements 30 by means of the conical middle part 38, to the periphery of which the wing elements are fixed in slidable or mounted arrangement. <IMAGE>
