我国生产的原油大多是高凝高粘高蜡的“三高”原油,给输油工作带来很多困难。温度越低粘度越大压降越大能量损失越大,所以一般采用加热的输送工艺并对管道经行保温绝热。近几年集肤效应伴热作为一项新的管道加热输送技术出现,它的基本原理、集肤效应伴热装置的基本构成和技术特点与工程计算方法及其更多的应用给输油气管道加热效率的提高带来一线曙光。 Most of the crude oil produced in our country is high-viscosity, high-viscous and high-wax crude oil, bringing many difficulties to oil transportation. The lower the temperature the higher the viscosity the greater the pressure drop the greater the energy loss, so the general use of the heating process and the pipeline insulation insulation. In recent years, the skin effect heat trace as a new pipeline heating delivery technology, its basic principle, the skin effect of the basic composition of the heating device and the technical characteristics and engineering calculation methods and more applications to the oil and gas pipelines Heating efficiency to bring a ray of hope.
