The Energy Consumption Analysis and Calculation for Proposed Linyi-Ji'nan Oil Pipeline

The energy consumption and calculation are made on proposed Linyi--Ji' nan Oil Pipeline. The heat transfer coefficient and actual effective thickness of polyurethane foam insulator in current soil and heavy soil humidity are obtained, as well as actual energy consumption value for the buried pipeline under the con- dition of insulation and non-insulation. The economic analysis on the energy consumption value shows that the comprehensive profits of insulated pipeline are betfer than that of non-insulated pipeline with high safety.
