加长管应用全生命周期费用探讨
Discussion on Whole Life Cycle Cost of Extension Pipe Application
摘要
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-scale application of 18 m extended pipe can be effectively controlled.关键词
