摘要:
为了降低长输管道环焊缝失效概率、确保管道全生命周期安全运营以及加快焊接施工进度,提出管道项目建设应采用18 m加长管。通过对建设期费用、运营期费用和潜在损失费用三个方面进行分析,并对18 m加长管与12 m钢管的全生命周期费用进行全面对比。结果表明,18 m加长管在建设期费用、运营期费用成本可以有效控制,总体费用与12 m钢管基本一致;18 m加长管道潜在损失费总费用较12 m钢管降低126.56万元;18 m加长管全生命周期费用较12 m钢管仅增加费用250.44万,整体投资增加0.35%,表明18 m加长管的大规模应用投资成本可以有效控制。
Abstract:
In order to reduce the probability of failure of girth welds in long distance pipelines, ensure safe operation throughout the entire life cycle of the pipeline and accelerate welding construction progress, it is proposed to use an 18 m extended pipe for pipeline project construction. By analyzing the construction period cost, operation period cost, and potential loss cost, a comprehensive comparison is made between the full life cycle cost of 18 m extended pipe and 12 m steel pipe. The results show that the construction and operation costs of an 18 m extended pipe can be effectively controlled, and the overall cost is basically the same as that of a 12 m steel pipe. The total cost of potential loss for an 18 m extended pipeline is reduced by 1.265 6 million yuan compared to a 12 m steel pipe. The full life cycle cost of 18 m extended pipe only increases by 2.504 4 million compared to 12 m steel pipe, and the overall investment increases by 0.35%, indicating that the investment cost of large?cale application of 18 m extended pipe can be effectively controlled.
