Industrial steam pipelines with frequent start-stop operations
Thread Content
Industrial gas pipeline with a pressure of 0.6 MPa, temperature of 230°C, and DN150 size; the steam supply for the enterprise is not continuous, and the interval between startups and shutdowns is approximately 10 to 15 days. So, are there any good measures to reduce fatigue-induced damage to the pipes?
If not needed, just turn off the user’s end device; that way it can be considered in standby mode, which will be much better {:3_54:}
If it liquefies slowly like that, it will take time for it to re-solidify, and the impact on the pipes might not be good either. I thought about creating a bypass, so that when it’s not in use, the fluid can flow back through the bypass pipe, thereby reversing the direction of thermal displacement……
Drain valves are installed at the ends of all steam pipes
{:3_68:} Ensure proper insulation and drain water regularly; it’s not necessary to keep an eye on the main valve all the time
Increasing the steam trap will ensure the proper temperature of the pipeline. This is the simplest way.
The small waste heat power generation unit mentioned earlier can address the issue of continuous steam demand and also generate electricity.
Install a small steam pipeline at the end point; when the client is not using steam, activate this pipeline to keep the main pipe at the desired temperature. The small pipeline can be pulled back to the supply point for further processing.
