The invention discloses an early warning method for failure of a natural gas denitrification solvent absorption pipeline, and the method comprises the steps: 1, measuring the sound wave voltage of each stretching detection film, and calculating the sound wave energy through computer equipment; 2, judging whether a point position corresponding to the stretching detection film is excessively stretched or not, and if so, performing early warning through computer equipment; if not, executing the third step; 3, judging the states of the two sides of the valve on the same pipeline where the stretching detection film without excessive stretching is located, and if the stretching detection film is in an excessive bending state, performing early warning through computer equipment; and if the excessive bending state does not occur, returning to the first step. 本发明公开了一种天然气脱氮溶剂吸收管道失效的预警方法，该方法包括：第一步，测量各个拉伸检测薄膜的声波电压，并通过计算机设备计算声波能量；第二步，判断上述拉伸检测薄膜对应的点位置是否出现过度拉伸情况，如果是则通过计算机设备进行预警；如果否，执行第三步；第三步，判断上述不存在过度拉伸的拉伸检测薄膜所在的同一个管道上的阀门两侧
