Numerical Simulation of Lined Steel Pipe Hydro-Forming Process
At present, the corrosion of oil tubular goods is becoming more and more serious in the exploitation of oil and gas wells, it is very significant to research new anti-corrosion measures of lined steel pipe in the application of oil tubular goods. A finite element analysis (FEA) numerical model concerning mechanical problem of lined steel pipe hydro-forming is established in this paper. Based on numerical simulation of lined steel pipe hydro-forming process, the relation of forming force and binding force between inner and outer pipes after forming of lined steel pipe is studied. And physical experiment of lined steel pipe hydro-forming is conducted, deformation laws of inner and outer pipes in the process of lined steel pipe hydro-forming are analyzed by resistance-strain test method. Test results show that forming force calculated by numerical simulation is close to the experimental data, the finite element analysis (FEA) model established in this paper is reasonable and can provide theoretical reference for the industrial manufacturing of lined steel pipe.
