摘要
Abstract
There are several cracks and gas pockets in weld of some SAWH pipe section,it evaluated two kinds of defects by choosing the largest size crack and gas pocket and adopting different standards,at the same time,it carried out microcosmic analysis to crack. The results indicated that this pipeline was unsuitable for running under normal temperature and below, the maximum safety working pressure of pipeline was 4.42 MPa, and the cracks had already been extended. Therefore,it suggests that it should run and maintenance this pipeline,or stop using below 4.42 MPa.关键词
