据《石油业》1983年第11期报导,苏联研制一种输油工程和储油工程用的电加热工艺管线系统,用来输送粘油和易凝油品(滑油、合成树脂和鱼胶脂等)以及石油产品。这种管线系统包括型电加热元件,它们沿管线表面直线或螺旋缠绕并用保温层原绝缘层复盖。在保温层和绝缘层之间铺设载流导线(电缆),通过接线头把电加热元件的低温接头连接到载流导线上。安装的管线系统连接到电网上,使输送粘油的管线加热。在有《输油自动化》
According to the “Petroleum Industry” No. 11 of 1983, it was reported that the Soviet Union developed an electric heating process pipeline system for oil transportation engineering and oil storage engineering for transporting viscous oil and easy-pouring oil products (oil, synthetic resin and fish glue Fat, etc.) as well as petroleum products. Such piping systems include electric heating elements that are linearly or spirally wound along the surface of the pipeline and covered with a layer of insulation that is primary insulation. Lay the current-carrying wire (cable) between the insulation layer and the insulation layer, and connect the low temperature connector of the electric heating element to the current-carrying wire through the terminal block. The installed pipeline system is connected to the grid to heat the pipeline that delivers the viscous oil. In the “oil automation”
