Flexible tensile silicon core pipe

The invention provides a flexible tensile silicon core pipe, and relates to the technical field of silicon core pipes. Comprising a pipe body, fixing ring blocks are arranged on the front side and the rear side of the pipe wall of the pipe body, a plurality of fixing holes are formed in one faces of the two fixing ring blocks, ring cavities are formed in the two fixing ring blocks, the pipe body comprises a core layer, a first pipe layer, a reinforcing layer, a second pipe layer and a corrosion-resistant layer, and annular springs are arranged on the inner walls of the two ring cavities. The tensile property and the overall strength of the pipeline connecting device are improved, the pipeline connecting position can be reinforced, the situation that traditional equipment is low in tensile property is avoided, the use safety of the equipment is guaranteed, the service life of the equipment is prolonged, and the service life of the equipment is prolonged. And the problem that the connecting strength of the pipe
