The steam tracing for the upper-mounted loading jack’s piping cannot be blown clear, even after freezing.

Installing the heat tracing tubes is complex, but steam has been used to blow on each line for air intake and condensate for 2 days yet it still hasn’t thawed. What’s the reason?
There may be several reasons why the ice cannot be melted after freezing: 1. Poor thermal conductivity: The thickness of ice buildup inside the heat transfer tube might be significant, making it difficult for heat to reach the center of the ice layer and thus reducing the melting efficiency. 2. Insufficient steam pressure: The steam pressure supplied may be inadequate, resulting in the thermal energy of the steam not being properly transferred to the heat tracing tube. 3. Insufficient steam temperature: If the temperature of the steam is not high enough to melt the ice, it will also prevent effective thawing. 4. High heat loss: If the insulation performance of the heating device is poor and the surrounding temperature is low, excessive heat loss can also affect the thawing effect. 5. Pipeline system issues: If there are blockages in the pipes or problems with the design, which prevent steam from being distributed evenly, this can also affect the thawing process. You can try the following methods: - Increase the steam pressure or temperature. - Improve the thermal insulation performance of the heat tracing tube. - Inspect and clean the piping system to ensure there are no blockages. - If possible, temporarily increase the number of heat tracing tubes or use other heating methods to assist with thawing. .
It is estimated that there are other areas where freezing has occurred; these can be heated and purged in sections
In areas with dead corners, heat them in segments and mark them clearly
