Corrosion issue with the heating wires of the device: For the part of our heating wires that is located outside the pipes, rock wool rope is used for wrapping; glass fiber cloth is applied on top of that, and paint is applied as well. After years of use, corrosion on the outside of these heating wires has caused the pipe walls to thin out significantly. Have you encountered such a problem? How can it be avoided?
Even with the best protection, they need to be replaced every year; it’s not possible to achieve perfect isolation, and external environmental factors have a significant impact~~~
The main issue is severe external corrosion; the thickness of the corroded seamless tube has reduced to that of thin iron sheet

Such problems are common in steam tracing pipelines; I’ve had quite a few leaks in my steam tracing pipelines recently, and they’re usually caused by sand holes. No problems have occurred with the high-temperature water heating. It is recommended to replace steam-jacketed pipelines regularly.
Internal corrosion is caused by high oxygen content in the steam, while external corrosion is due to environmental factors; apply high-temperature anti-corrosion paint.

It’s normal for corrosion and pitting to occur after a few years of use; if money isn’t a concern, replace it with rock wool and aluminum sheeting. During routine maintenance, do not step on the outer insulation layer of the pipelines; it is still useful to maintain good sealing.
