In the actual engineering application, how should we choose the appropriate electric heat tracing cable? This should be analyzed in detail according to the specific situation. From the perspective of technology and economy, there are generally the following principles for selecting the type of electric heat tracing.
First of all, if it is in the oil and gas separation area, because there are several types of ground oil pipelines, oil and gas separation buffer tank sewage pipelines, natural gas separation equipment and liquid level gauges, and the requirements for temperature control are relatively high, constant power is generally used. electric heating cable. Liquid level gauges generally use single-phase constant power electric heating cables, and other types use three-phase constant power electric heating cables, so that a set of explosion-proof distribution boxes and temperature controllers can be used to unify them. However, it is worth noting that the selected distribution box, junction box, temperature controller and other things must meet the requirements of explosion-proof, and no accidents can occur.
If it is to heat the water tank or water pipeline far away from the explosion-proof area, because the traced body is not too concentrated, the requirements for temperature control are not high, as long as the temperature can be maintained within a certain range, it can achieve the required In this case, self-controlling electric heating cables are generally selected, because such electric heating cables can save a lot of money without distribution boxes and temperature controllers.
If it is in an area with more bends. Where it may be necessary to install electric heating cables in a cross or overlapping manner, it is naturally not possible to use a constant-power electric heating cable, but a self-controlling temperature electric heating cable. The constant power electric heating cable can not only cross, overlap, and cut, but the self-controlled temperature electric heating cable can be cut at will, which can ensure the integrity of the electric heating.
