Can anyone provide me with the heat range tolerance of Sch 40 PVC? I
am considering using it as a temporary fix for my auto cooling system.
Could it blow out or bend in such high temperatures?
Thanks,
Tony D

How about CPVC? For hot water.
I would think the plastic would have problems with all the dry heat, and
make it brittle.
It may work for a day or two, but I would not want to guess where it can
strand you...

Am sure its available from ASTM specs. Am also sure the burst pressure is
directly related to the temperature of both the liquid it carries and the
temperature of the surrounding environment.

Do an experiment...
Heat up a pot of water on the stove to boiling.
Put a length of PVC in it, six inches or so, and let it
sit in the boiling water for a couple minutes..
Wearing gloves, fish out the PVC and see how flexible it is....
If it is easy to bend, there will definitely be a problem.....
Water in an auto cooling system is very close to boiling...

In a normal automotive cooling system, its ABOVE regular boiling point (212
oF)
The pressure/antifreeze in the system allows the coolant to run higher w/o
boiling
