How to deal with solidification in the residue oil pipeline
Thread Content
I need to know how to deal with solidification in the residue oil pipeline. The softening point is around 75, and the pipeline is equipped with steam heating; will turning on the heating system help to dissolve the solidification?

The best approach is to heat and melt it in sections, using external steam for heating, and keeping one end of the pipeline open to prevent pressure buildup.
What other good methods are there besides turning on the heat tracing? If that doesn’t work, then adjust the pressure and temperature of the heating steam, or increase the time
What kind of pipeline are you talking about? We have different pipelines, and therefore different solutions are required! ! ! :):)
Wrap a few more steam belts around the pipeline, cover them with felt, and handle it section by section.
It won’t soften; use steam to push it. If that doesn’t work, then cut the pipe
It is recommended to use 1.0 MPA steam as heat tracing, and activate the heat tracing system; (a valve must be opened at the other end of the pipeline to prevent pressure buildup.) A pump should be started at the other end, or steam can be used to apply intermittent pressure. If it doesn’t work in a day, then tube removal is the only option
It depends on the specific diameter and length of the pipe; if the diameter is large, relying solely on heat tracing isn’t sufficient； If the condensed portion is short, it is recommended to remove the insulation and use 10 kilograms of steam directly.
Set up a hotline – use steam to push; P; P; P. . . . . . . . . . .
The main pipeline has been connected using steam and fire, but the drain valve has clogged again.
We have encountered this problem as well; it was caused by residue, and at that time we used steam to clear it. Now that the main channel is unobstructed, the branches and drain lines are easier to deal with – steam can be used for that. If it’s a drain line, it might be blocked; use a wire or welding rod to clear it, but be sure to pay attention to safety.
