摘要
从理论与实际结合出发,分析了管道腐蚀后的剩余强度。介绍了目前国际上普遍采用的以美国标准(ANSI/AMSE B31 G)为代表的对管道剩余强度的评价方法,以及该方法在我国管道的适用情况。通过对表面有特定缺陷的不同材质、不同管径的试验管材进行的水压爆破试验,并将爆破试验结果与美国标准中的理论计算结果相比较,验证美国管道法规在我国的适用性。这将对我国长输管道的运行与管理具有一定的参考价值。
The article analyzes pipeline's residual strength after corrosion proceeding from theory combining with practice, introduces an evaluating method of pipeline residual strength commonly applied internationally at present, taking American Standard (ANSI/AMSE B31 G) as representative, and an applicable condition of the method for our country's pipeline. Based on hydraulic explosive tests on different material qualities with given surface defects and different pipe diameters, and compared explosive results with theoretical calculation results in American standard, it is evident that the regulation of American Standard is applicable for our country. This will has a certain reference value to the operation and management of our pipeline.
