The issue of insulation for acidic water pipes
Thread Content
What are the insulation requirements for acidic water pipes in refineries in the northern regions? Is heat tracing required or insulation? I would appreciate some guidance from those with more experience
That’s how I understand it. You’re asking whether to use heat tracing for insulation or thermal insulation; heat tracing provides heat, while thermal insulation does not. It depends on whether heat loss in the pipeline due to thermal insulation will have an impact on the manufacturing process. If there is an impact, then heat tracing is necessary, otherwise thermal insulation can be used. The insulation type seems to have little to do with the medium inside the pipeline; when selecting the pipeline grade, you need to take into account the influence of the medium.
The temperature of the acidic water after it exits the container is around 40 degrees. The concern is whether it will freeze in winter; therefore, there is some hesitation between using heating elements and insulation. Personally, I lean towards insulation, as heating elements require a lot of energy
