中石化管道储运分公司所属的甬沪宁管线目前年输量3千万吨以上,鲁宁管线扬子分输站年输量240万吨。因此,原油流量的计量准确度直接关乎供需双方的经济效益,如控制不好,很小的误差都会给双方带来经济损失。经过多年运行发现,由于体积管计量系统在设计等方面不尽合理,给原油计量带来一些问题。现对体积管在使用中出现的各种问题及解决方案进行分析。一、体积管计量系统存在的问题及解决方案甬沪宁管线配备的是美国SMITH公司的体积管,型号为Bi-Di,管径为489mm配10寸将军四通阀。体积
Sinopec Pipeline Storage and Transportation Branch of the Ningbo-Shanghai-Nanjing pipeline currently has an annual output of more than 30,000,000 tons, Luning pipeline Yangtze sub-station annual output of 2.4 million tons. Therefore, the measurement accuracy of crude oil flow directly relates to the economic benefits of both supply and demand. If the control is not good, a small error will bring economic losses to both parties. After many years of operation, it has been found that due to the unreasonable design of the volumetric pipe gauging system, some problems are brought to the crude oil gauging. Now the volume of the tube in the use of various problems and solutions to be analyzed. First, the volume tube measurement system problems and solutions Ningbo-Shanghai-Nanjing pipeline is equipped with the volume of the United States SMITH company, model Bi-Di, diameter 489mm with 10-inch general four-way valve. volume
