Regarding thermal compensation calculations
Thread Content
In the thermal compensation spatial verification formula, is the vector sum of the three directions always referring only to the XYZ directions, no matter how much the path bends? How does one determine the straight-line distance between two fixed points in space?
You mean the empirical formula, right? It should be the sum of the values in each of the 3 directions, and the fixed linear distance can be calculated using geometry; middle school geometry is sufficient for that. It can only be used for reference; for accuracy, software calculation is required
Yes, it’s the formula from the power pipeline design manual, used for approximate checks. What software is it? For the verification of spatial pipe compensation in cases with branch pipes, what should be used as a reference for calculation? Are there any examples in books?
There are many stress analysis software programs, and most discussions on forums concern CAESAR II – it’s not possible to use formulas for cases with branches
I would like to ask, what is thermal compensation? When should I consider it?
You know the principle of thermal expansion and contraction, right? It needs to be taken into account when there is a large difference between the operating temperature and the installation temperature.
