Winter low temperature situation oil extraction plant engaged in crude oil mining and conveying operations, oil pipeline will occur because of low temperature medium condensation, oil dewaxing and other phenomena. So need to heating cable insulation program to solve the problem of oil well and oil pipeline insulation, through not companion heat insulation way to understand, oil extraction plant use more is electric heating system insulation.


                   The oil extraction plant applies the electric heating system heat preservation, in reduces the oil pipe plugs the wax and scrapes the wax phenomenon, increases the pump efficiency, reduces the pumping machine load, stabilizes the oil production, may choose the temperature control electric heating cable preservation system, through heating cable tape to wind or straight to lay in the oil-producing pipe, energized to generate the heat, for the oil-producing pipe to raise the heat, thus lets the oil temperature keep in the crude oil which contains contains the wax and the thick oil above the critical point.

                   In the transmission of crude oil pipeline can be used according to the need for different types of electric heating cable, usually use self-limiting temperature accompanied by tropical and constant power electric accompanied by tropical. The self regulating temperature heating cable realization automatic temperature control, any cut, cross overlap winding, can be applied to the pipeline is not very long, the temperature requirement is not very high, the installation is more complicated environment. Constant power electric heating cable tape to use the distance is longer, accompanies the heat temperature is higher, may apply to the long distance, the big caliber, the temperature request is high, the environment is more complicated occasion.
