电热带保温技术主要用于油田、炼油厂及化工厂的管道、阀门及容器等的保温,特别是中短距离维持较低温度管道的伴热保温,油田高粘度、高凝点石油的伴热采输。本文就电加热带的结构、应用特性、工作原理、工作状态分析、应用设计及设计要点做了论述。指出电热带保温的设计、应用、施工是各种电热保温中最方便的一种。
Electricity thermal insulation technology is mainly used in oilfields, oil refineries and chemical plants pipes, valves and containers such as insulation, especially in the short-term to maintain a lower temperature pipe heat insulation, oil field high viscosity, high pour point oil heat Acquisition and transportation. This article discusses the structure, application characteristics, working principle, working condition analysis, application design and design points of electric heating belt. It is pointed out that the design, application and construction of electric thermal insulation are the most convenient kind of electric thermal insulation.
