Abstract: The theoretical calculation method is applied to pipelines in this paper The function-cost equation in oil and natural gas pipelines is deduced. According to practice, the curves of F-C are drawn. The results show that this equation is generally used for oil-gas pipelines. It is also of certain practical significance and of value for reference.
