:ok first off the 73 degree temp. is a test temp. in that all basic test are done at 72.5 degrees kind of a industry standard that is just a press. rating at that temp. standard pvc is good i believe to about 100 cpvc is good for a higher temp. the best thing to do is check with a manf. rep. on the pvc. if there is a HAJOCA in your area call them and tell them the application and the temp ( its good to know the temp. that the pipe will achieve during operation) remember that it's not a good idea to excede the pipe max. temp. rating by 80% i'm not sure what type of drycleaning plant you are involved in but i personally like to stay away from all pvc in a commercial application you should also check to see if pvc is rated for vacumn applications another thing to check on is are any solvents going to be used in this vacumn operation. if these vapors are going to be sucked up by your pvc then how is the pvc going to react to this solvent. hope this helps if not hit me back CAPTAIN
