Due to the importance of oil resources, so to ensure the normal exploitation of oil, oil extraction tree is a self-injection wells and machine wells and other wellhead devices used to extract oil. It is the upper most part of the oil and gas wells to control and regulate oil and gas production of the main equipment, its valves play a role in closing the switch, due to the valve is in the open environment, when the winter comes, the temperature is relatively low when the oil extraction tree valves may be frozen to affect the use.

With the continuous development of electric accompanied by heat technology, more and more equipment began to use electric heating cable insulation to prevent freezing. For this reason, we can use the electric heating cable tape to help the oil extraction tree valve heat preservation, through the electric accompanies the heat preservation, only need to heating cable tape to lay on the equipment, install the thermostat, if it is the use of self-limiting temperature electric the heating tracing cable tape, the temperature does not have the special requirements can not use the thermostat. When the electric accompanies the heat system to install, turn on the electricity, the electric heating tracing cable will be through the electric energy conversion for the heat energy way for the equipment accompanies the heat preservation, very convenient, easy to operate.

At present, the electric heating system has been widely used in petroleum, chemical industry, power plants and other pipeline equipment insulation, electric heat conversion efficiency is high, accompanied by the heat effect is good, by the user's wide range of trust.
