Temperature Cycles

Temperature cycles describe cyclic effects on the piping. Each cycle is characterized by:

It is assumed that amplitude changes proportionally to temperature difference relative to the cycle with the largest difference.

To add cycle properties, click "Add"; to delete, click "Delete". To edit the correlation of the current cycle's difference to the maximum cycle's difference or frequency (number of cycle with the current temperature during set interval), double click the desired field. Then, press Tab or click on a free space in the dialog window. To change the period, select the corresponding cell and click on the symbol that appears in the right corner. Select the desired cycle from the list.

Description

Maximum temperature, Тmax

Maximum design temperature among all elements

Temperature factor, ki

Correlation of current cycle's maximum temperature difference to maximum temperature difference ki = ΔTi /max - Тinstallation)

Тinstallation - Ambient temperature

Тmax - design temperature from pipe properties

ΔTi - temperature difference ΔTi =max - Тinstallation) ki
