[0043] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings:
[0044] Such as figure 1 As shown, the full-scale marine engineering pipeline corrosion experiment equipment is mainly used to measure the state change of the full-scale experimental pipeline 8 in seawater corrosion solution under the condition of applying complex loads, including: axial load loading devices 1, 2, 5. Torsional load loading devices 6, 7, bending load loading devices 11, 14, 15, 16, corrosion test water tanks 9, 10, 12, 13, pipeline fixing devices 17, 19, 20, 21, 22, 23, 24, The experimental equipment fixes the heat preservation outer wall 18. Among them, the corrosion test water tank 10 and the corrosion test water tank 13 are sealed with the test pipe 8 through anti-corrosion rubber gaskets. The test pipe 8 and the axial load and torsion load loading device are connected by flanges 3 and 4, and the test pipe 8 and The bending l...
