Again, you are confusing two separate issues.
The pipe effectively has one open end, with water being pushed into it under pressure. Your hypothetical loss of volume won’t happen, because there’s an endless supply of water behind that volume which cools, to replace it.
If your granny canned things like mine did, that’s an entirely different set of facts.
