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, so it is very significant to study new anti-corrosion measures of lined steel pipe. 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 correlation of forming force and bonding force between inner and outer pipes after forming of lined steel pipe is studied. Furthermore, physical experiment of lined steel pipe hydro-forming is conducted, and deformation laws of inner and outer pipes in the process of lined steel pipe hydro-forming are analyzed by resistance-strain test data. Test results show that forming force calculated by numerical simulation is close to the experimental data, so FEA model established in this paper is reasonable and can provide theoretical reference for the industrial manufacturing of lined steel pipe.
