What is the impact of medium temperature changes on pipelines?
Thread Content
As the title suggests, how does the change in the temperature of the fluid flowing through the pipeline affect it, especially when this temperature fluctuates frequently within the range of 70 to -15 degrees Celsius? The pipe material is 20# steel.
I don’t have much research on materials. But I think frequent expansion and contraction of the pipeline must have an impact on its service life. Additionally, it is necessary to consider how the medium changes under the influence of temperature.
I’m not very familiar with the materials, but it seems to me that pipe expansion only happens once, at the beginning
Given that it was designed this way, the original designers must have taken this issue into account; it should have little impact on the pipes!
I would like to ask the pipeline professionals: is it necessary to change the material to low-temperature steel?
Frequent changes? Is this a thing that happens?
It’s not a big problem, right? The temperature of high-temperature heat transfer oil, which is over 300 degrees, also changes frequently.
I think it will have an impact; with changes in temperature, everything undergoes thermal expansion and contraction, which can affect its service life. That’s how I understand it
There are not many problems with the pipes in the equipment area, as they are relatively short and have many bends, which helps to minimize issues. However, for the pipes in the main ductwork, this issue needs to be taken into account, and fixed supports should be installed
