The tube dissipates heat to heat the oil in the tube. The electric heating belt uses the electric current to generate heat to trace the oil in the pipe body. However, for this structure and form of heat tracing, the steam tube is a single-form circular tube, and the contact between the steam tube and the tube body is a linear arc-to-arc contact. The contact area is very small and there is almost no heat conduction, so the heat conduction efficiency very low.
电热带是利用了宝贵清洁能源电能实现其55℃的低温加热节能意义上讲是资源在现有技术条件下的浪费。The electric heating belt utilizes the precious clean energy electric energy to realize its 55°C low-temperature heating and energy-saving sense, which is a waste of resources under the existing technical conditions.
