Title: Metallic tube and manufacture thereof
Inventor: MEGATA TADAO
IPC: B21C37/06
Filed: 1989-03-22
Abstract: PURPOSE:To cancel added tensile stress with residual stress and to prevent cracks from arising by constituting the tube of metal in which the inner layer is smaller in Young's modulus than the outer layer or larger in thermal expansion coefficient that the outer layer and making its circumferential compressive stress remain on its inner layer and near its inner layer. CONSTITUTION:In a multilayered tube, the inner layer 1 is composed of the metal smaller in Young's modulus E or larger in thermal expansion coefficient than the outer layer 2. Since the inner layer expands more largely than the outer layer when this metallic tube is located at a high temperature and in a hydrostatic pressure, a plastic flow is generated toward the inner layer. A quick cooling is actuated so that this state is not recovered, the pressure is removed to form an elastic compressive residual stress in the circumferential direction, especially, on the inner layer. Thus, through a tensile stress is given to the metallic tube, it is cancelled and relieved by the compressive residual stress, cracks can be prevented from arising on the inside surface of the metallic tube and when it is used for a nuclear fuel covered tube, most of defects by stress corrosion cracking and lift-off can be prevented.
