The cold extrusion connection technology of aviation stainless steel pipeline was studied. The theoretical model of cold extrusion pipeline connection structure was established. The theoretical model was simulated by ANYSY, and the simulation analysis was verified by experiments. The results show that the simulation analysis and experimental results are basically the same. The connection mechanism of cold extrusion pipe connection technology was analyzed, the results show that the deformation force is an important source of cold extrusion connection strength.
