Calculations must be carried out using the thermal calculation formulas specified in the pipeline design standard GB50253; only then are they legitimate.
I understand that what the owner is concerned about is the calculation of the heat tracing load for the overhead pipes. The second floor discusses the \"Design Code for Oil Pipelines\", which is applicable to long-distance oil transportation pipelines. Heating is rarely used in such pipelines, so it will not be discussed here. To determine the heat tracing load for overhead pipelines, it is first necessary to identify the heat losses of the pipelines, which mainly include heat conduction and convection. For specific details, refer to the \"Design Code for Steam Tracing of Petrochemical Pipelines\"; it’s SH3010.
Reply to 3# Storage and Transportation Superhero: Thank you for your answer. Perhaps my wording was a bit unclear; what I’m looking for is indeed the heat maintenance load required for the oil in long-distance pipelines.
Long-distance pipelines are generally laid underground; if they are used to transport heavy oil, fuel oil, etc., insulated pipes (\"yellow jackets\") can be employed, but heating is usually not provided. For the heated transportation of buried long-distance pipelines, temperature drop calculations must be carried out, and it is based on these results that a decision is made as to whether an intermediate heating station should be installed. For relevant calculations, refer to the \"Code for Design of Oil Pipelines\" (GB50253-2003, 2006 edition). If the pipeline is installed above ground, a heat tracing line can be installed.
Suggestion: The heat dissipation of the pipeline should be calculated in accordance with GB50253, taking into account as well the additional heat dissipation caused by the temperature rise of the heat tracing pipes； The heat supplied by the heat tracing tube to the supply pipeline is calculated in accordance with the SH3040 Design Code for Pipeline Insulation and Jacketing in the petrochemical industry.
