How to select the industrial electric heating cable? For specific situations and specific analysis, it is not appropriate to divide by oil field block. All are selected with constant power electric heating cable or both are selected from temperature-controlled electric heating cable. To comprehensively consider from a technical and economic perspective, it is recommended to refer to the following selection principles

1 In the oil and gas separation area consisting of gas separation buffer tank and natural gas separator, the surface oil pipeline, oil and gas separation buffer tank sewage pipeline, natural gas separator, and liquid level gauge are relatively concentrated, and the temperature is also strictly controlled, and a constant power electric partner can be used Tropical, where the liquid level gauge uses a single-phase constant-power electric heating cable, and the other uses a three-phase constant-power electric heating cable. In this way, a set of explosion-proof distribution boxes and temperature controllers can be used for unified control. The thermostat must meet explosion-proof requirements.

2 The water supply tank and water supply pipeline are generally far away from the explosion-proof zone, the heated body is not concentrated, and the temperature control requirements are not high. As long as the water temperature is always maintained within a certain range, the design requirements can be met. Therefore, if the self-controlling temperature and electric heating cable is used, the heat tracing accessories such as distribution boxes and temperature controllers can be omitted.

3 In areas with many valve elbows, cross-overlay installation may occur, so it is not suitable to install a constant power electric heating cable (with a separate layer of electric heating wire), and it is easy to choose a self-controlling electric heating cable.

4 From the perspective of design and installation, the constant-power electric heating cable is generally limited by the length of the section. If a section length cannot be found when cutting, the part of the heating cable will not work, which not only affects the heat tracing effect of the pipeline, but also causes It becomes waste; and the self-controlling temperature heating cable can be cut at will, which can ensure the integrity of the heating cable.
