Problems in the engineering calculations for equipment insulation
Thread Content
We have a 1600 model heat exchanger unit for insulation purposes. During the project acceptance process, it is required to calculate separately the quantity of work related to the upper and lower flange assemblies. The calculations are carried out using the formulas for flange insulation, moisture protection, and protective coatings: V=π×(D+1.033δ)×1.5D×1.033δ×1.05×N (5-10) and S=π×(D+2.1δ)×1.5D×1.05×N (5-11). Here, N represents the number of flanges. The equivalent length of these flanges is 4.8 meters; as a result, the amount of work required for them is even greater than that required for the equipment’s cylinder itself
Is this way of calculation reasonable? It seems that the flange shouldn’t be calculated separately
If not calculated this way, what standard should be used?
The quota includes formulas for calculating the heat insulation value; the amount calculated for flanges is somewhat higher than what is actually used, while the value for valves is lower. It’s necessary to take all these factors into consideration, otherwise there will be no basis for comparison
It is a φ1600 tubular heat exchanger; it’s not a pipe flange. How is the flange for the equipment’s head calculated?
The specification does not mention the equipment head flange separately
