How to choose the cable type for pipeline electric heater?
First of all, if it is in the oil and gas separation area, because there are several types of surface oil pipelines, oil and gas separation buffer tank drain pipelines, natural gas separation equipment and level gauges, and the temperature control requirements are relatively high, constant power is generally used. Electric heater cable. The liquid level gauge generally uses a single-phase constant power electric heater cable, and the other several use a three-phase constant power electric heater belt, so that it can be carried out with a set of explosion-proof distribution boxes and temperature controllers. Unified control, but it is worth noting that the selected distribution box, junction box, temperature controller and other things must meet the requirements of explosion-proof, and there should be no accidents.
If you are tracing water tanks or water pipes far away from the explosion-proof area, because the heated body is not concentrated, the temperature control requirements are not high, as long as the temperature can be maintained within a certain range, it can achieve the required In this case, the self-control temperature electric heater belt is generally selected, because such an electric heater belt can save a lot of expenditure by eliminating the need for power distribution boxes and temperature controllers.
If it is in an area with more bends. Where it may be necessary to cross or overlap the installation of electric heater belts, it is natural not to use constant power electric heater belts, but to use self-controlled temperature electric heater belts. The constant power electric heater belt can not only not cross, overlap, or cut, but the self-control temperature electric heater belt can be cut at will to ensure the integrity of the electric heater.
