Abstract：The forming principle of double metal clad tube hydraulic expansion is analyzed firstly, after acquired material mechanics performance parameters of the base pipe and liner, this article study the bulging compound criterion of the base pipe and liner.The residual contact pressure stress between base tube and liner is studied.At the end of the paper, the different liner material for bulging residual contact pressure and the influence of compressive stress are studied.These studies provides important basis for practical engineering.
