The antifreeze and heat preservation design of the pipeline needs to design heat preservation measures according to the medium temperature and process requirements. Otherwise, under severe weather conditions, it is easy to freeze and crack the branch pipe of the liquid pipe. Therefore, the piping has its own special requirements and cannot be designed according to ordinary requirements. At present, there is no systematic and perfect equipment, pipeline anti-condensation and anti-freezing criteria in the design standards implemented in China. It is necessary to combine each pipeline and equipment on site, and focus on the design method description and related precautions for process pipeline anti-freezing and heat preservation to ensure that the anti-freezing Insulation effect. Heating and heat preservation is a commonly used form of heat preservation for chemical material transportation pipelines. The heat dissipation from the transportation pipeline to the environment is compensated by heating, so that the temperature of the material in the transportation pipeline remains unchanged or does not freeze. However, the heating and heat preservation transformation of existing chemical plant pipelines is very difficult, and heat preservation equipment needs to be customized, resulting in extremely high costs.
