Latest Natural Gas Changes

As an addendum, pipes (liquid or gas) at or below 10% capacity will not break. Whether or not this is intended behavior is unknown, add it to the very long list of such things. It's not entirely unreasonable though. You could consider such a pipe to be 90% empty, in which case there is some room for expansion due to state changes. Perhaps liquid -> gas is a stretch due to how much that expansion is, but liquid -> liquid seems fair.

Water is weird in that it expands when it freezes.  Most materials contract.

That is true but still when something turns solid in a liquid pipe it will probably block the flow. Similar turning liquid in a gas pipe might cause similar porblems since you`d need much higher pressure to keep the gas flowing.

Oil turning into petroleum should change it`s density which might lead to pipe damage. Also doesn`t cooking oil to petroleaum produce a small amount of nat gas along the way?

Nope.  The oil just turns 100% into petrol.

Really?  Really really?  It can’t be that easy. Being able to state change oil to petroleum while in the pipe is invaluable.

I guess it still can’t be done in a metal refinery directly but indirectly yes, very yes.

I should clarify that the state change doesn't actually occur in the pipes, they just don't break. Crude won't change to petroleum until it leaves a vent. Not as useful now that NG boiling isn't a thing. You could make NG boilers super easy, Boris had a thread about it. You can still use it to make SG if you wanted to. No worries about managing the petroleum transition, just heat the crude up to SG temps then let it out. Run the SG back along the pipes to exchange heat and you have a dead simple SG boiler.

 It's still helpful here and there though if you don't mind taking advantage. Takes away the problems of overheating or overcooling something.

Ah that is a little different but that works too.

Yes, I do :
