Metal Refinery is storing 45 tons of steam inside of it.

This is not a bug. As the metal refinery will store the heated coolant inside and release it after each order. That means water shouldn't be used as coolant. Super coolant is the best, but crude oil works too. 

Not sure it will work, but you could cool the refinery to turn it back into water so it can leave out the pipe.
Otherwise, you could try "empty storage" but not sure if the steam will go into the environment or into canisters.

Edit: LMAO. DO NOT EMPTY STORAGE. I dumped steam all over your base that quickly turned into water.

Yeah, you gotta either stop using water, or check the temperature before it comes in. From quick testing I did yesterday, smelting steel increases polluted water by 92F or so. Your input PW would have to be 130F or less to be safe.

Also, unrelated, your petroleum generators are powering 1 smart battery that are automated to stop at 100%. Just one burst of all those generators gives you about 20-30% of a battery charge. You are wasting a ton of petroleum, making a ton of CO2, and heating everything up for no reason. Set that battery to 70/60 and you will get a battery filled to 90% or so going from 60% even with the shutoff at 70%.

This bug still exists.
Cooling Metal Refinery with +90°C water is easy exploit to use. You only need disable auto repair on the output pipe and you can use Metal Refinery as long as you like without empty coolant at all. It just stores more and more of 140°C water inside it. My current one has hundreds of tons of it.

Expected Result:
- If it contains water +100°C Metal Refinery breaks and Steam is released into air.
or
- You should not be able to operate Metal Refinery with broken output pipe.

I guess second option is easier to implement and more challenging, because you wont be able to use metal refinery with hot water at all.
