[MW:8223] Hydrotest

Hi all¡¡¡
 
Please could some of you tell me about changes of pressure with changes in temperature?
 
We have done a hydrotest twice on the same pipeline trap and both were rejected by the cliente because next:
 
1.- Firstone was rejected because pressure and temperature decrease
2.- Second one was rejected because temperature decrease and pressure keep without low.
 
And the main question is:
 
Does the pressure have to change by changing the temperature?
