Discussion on the calculation of pipeline insulation thickness
Thread Content
To calculate the adiabatic thickness, using the formulas provided in the standards yields a value that is relatively small; therefore, it is necessary to include a margin. As for how much this margin should be, what values should be used as a reference to determine it? For example, in terms of heat retention, the amount of heat calculated should be less than the maximum allowable heat loss. Then which value should be used as a reference for heat preservation? Thank you!
How can one determine when the calculated value is small? Generally, the calculated values according to standards include a large margin of safety. If you refer to someone else’s previous drawings or similar materials, that only indicates that that person has chosen a relatively large subjective margin of safety
I also feel that the calculated values according to the standards should include a margin of safety, but my colleague said this is the minimum requirement, and a margin still needs to be included.
To figure out this issue, it is necessary to start calculating from the source: how much margin there is, and how to calculate that margin. Because the specifications contain only simplified content, with just the final formula
Agree with the view from the fourth floor. In any case, basic calculations are necessary; otherwise, the errors will be too large
Yes, we all do the calculations, but there seems to be no standard for determining how much margin to leave in the calculation process.
Habeas corpus: it’s normal to have some margin, so it’s sufficient to use a few different specifications. For example, the minimum is 30, and for temperatures above a certain level, it should be 50
