根据φ377埋地管道工业规模预备试验的初步结果,在土壤电阻率相当高的新疆库鄯输油管道工程中,分别依靠三组长1000m的带状镁合金牺牲阳极,在两个相邻的测试桩上以两根并联(2×250m)或四根并联(4×125m)的方式埋设,使得长81km、131km和107km的三处φ610长输管段受到了有效的阴极保护。
According to the preliminary results of the pilot preparation of the φ377 buried pipeline industry, in the Kuqa pipeline project with high soil resistivity, three groups of strip-shaped magnesium alloy sacrificial anodes with a length of 1000m are relied on, respectively. Two adjacent test piles Two parallel lines (2 × 250m) or four parallel lines (4 × 125m) are buried in the tunnel so that the three long 输φ610 pipelines 81km, 131km and 107km long are effectively protected by cathodes.
