Is it necessary to insulate the low-voltage flare lines inside the coking unit?
Thread Content
Today I suddenly noticed that the low-temperature flare pipelines inside our coking unit are insulated, while the low-temperature pipelines in other units are not. I’m not sure whether this is part of the design or if there was an error during the insulation process.
No insulation is required; gas lines generally contain very little moisture. Although there is some condensate, its freezing point is extremely low, so freezing does not occur under normal circumstances. Therefore, insulation is unnecessary, and we don’t use low-voltage lines anywhere in our facility.
There’s no need for insulation; it’s sufficient to ensure smooth flow using low-wattage jars along the way. Are all the low-wattage wires in your installation area insulated?
Insulation is generally not used, unless it is a pipeline for acidic gases or similar substances that will condense and crystallize when cooled; in such cases, not only insulation but also heat tracing is required
I can ask how the design team considered these aspects during the design process, and what is the purpose of insulation? Generally, low-pressure flare lines do not have insulation; neither catalytic nor coking units have insulation. Unless there are specific requirements or special considerations during the design phase, they should be clearly stated.
The other similar pipelines don’t have insulation; it seems that there’s too much insulation on this one
They’re trying to maintain error tolerance for heat preservation, in order to earn more from the projects. ;P;P
Useful in the north, not needed in the south; generally used to prevent condensation at lower temperatures in winter.
It has no preventive effect; the condensate always collects in the low-pointed pots
Not only is insulation unnecessary, but in fact it is not allowed either. Low-wattage pipelines have low temperatures on a daily basis; if insulated, it is impossible to achieve a complete seal using current construction techniques. During rainy days, rainwater will seep into the area beneath the insulation, and the accumulation of this water can lead to corrosion of the pipelines. Over time, this increases the risk of pipeline leaks, posing a safety hazard.
