How to prevent leaks in DN20 steam tracing pipes during production?
In terms of process adjustments, I can think of no solution; even if we shut it down, we don’t have any additional measures to prevent rusting. All we can do is seal the leaks. It’s necessary to ensure that it’s possible to seal these leaks or to shut down the system temporarily during the design phase. There should be no steam in the pipeline, as water hammer can easily cause damage.
Ensure there is no liquid water hammer in the steam, and no steam enters the condensate; if water hammer occurs, make adjustments promptly.
Is this due to corrosion issues? Is the leakage still caused by high steam pressure?
From the perspective of preventing freezing, low-pressure steam tracing is sufficient; generally, it is corrosion or issues with the quality of the pipeline itself.
The temperature requirements for heat tracing are not very high, so there is no issue with high steam pressure. However, heat tracing pipelines are usually thin and long, which leads to severe water hammer effects. Additionally, there is the problem of pipe corrosion, as well as vibration.
