Abstract
Based on the bimetal pipe hydraulic composite process, it put forward a way to control bimetal pipe hydraulic composite effect by using the expansion characteristic curve of material limit elasticity. The contact stress test showed that in order to get the best composite effect, the material grade of outer tube should be as high as possible, and stiffness matching material should be adopted for lining tube. Under the condition of defined material for outside and inside pipe, the greater in water pressure in course of recombination process, the much more elastic potential energy to be obtained, and the recombination effect will be much better. The hydraulic expansion test result showed that when the expansion process is in the inflection point from elasticity deformation to plasticity deformation stage, the bimetal pipe will get maximum residual elastic potential energy, which can ensure that double metal layer to achieve the best attaching status.关键词
