Xadhoom Posted November 7, 2018 Share Posted November 7, 2018 i have problems with pipes breaking for me. even the best ceramic pipes will have temperatures change of the gas or liquid inside even though the temperature of the pipe itself don't change temperature. i find this behavior weird. a major problem i have is that when a pipe is connected to a building, the temperature inside the pipe will change causing the gas/liquid to have a phase change and breaking said pipes. it have made my space program so frustrating to manage as i feel i constantly need to have my dupes running around and fixing pipes.

clickrush Posted November 7, 2018 Share Posted November 7, 2018 I assume you are pumping cold steam through ceramic pipes to supply rockets. The problem is that the pipes will only very slowly heat up if made from ceramic but they still in fact do, you just didn't notice it. You can avoid this problem for example by pumping hotter steam. The pipes will still heat up over time but the steam won't condense. Steel pumps have an overheat temperature of 275°C. Another solution is to slowly preheat or precool radiant pipes out of gold amalgam (or gold for liquid pipes) or any material with a low SHC, by only pumping very small amounts using a valve. If the amount is small enough it won't phase change. I forgot the exact numbers for both gas/liquid pipes, so do a quick forum search.

suicide commando Posted November 7, 2018 Share Posted November 7, 2018 The best solution to this is to ensure there's no volatile liquids in your pipes. For instance, for my steam rockets, when I want to fuel one, I use a switch, that is hooked up to some automation to only give a single quick pulse, which then fires up some buffer gates for 900 seconds, which then enable 2 steel gas pumps inside an isolated chamber with high pressure steam in it, that is maintained by pouring more water into it and heating it up with aqua tuners as needed. This sends about 900 kg of steam through my isolated pipe to my steam rocket, filling it up without anything being left in my pipe.

Xadhoom Posted November 7, 2018 Author Share Posted November 7, 2018 hmm. the 900 sec trigger would have been useful. as long as the gas was moving there was no problem with it condensing. but even so, having pipes in VACUM! with stuff on the floor will heat the materials INSIDE the pipe! trough what medium does the heat transfer happen!? i know radiation head is a thing in real life, but as far as i know, its not coded into the game. also i ran insulated pipes trough insulated tiles, and STILL i got heat transfer! WHAT!? insulated tiles hardly has any heat transfer normaly, but i run a pipe inside it, suddenly its like 100x then vs other tiles surrounding said insulated tiles.

Neotuck Posted November 7, 2018 Share Posted November 7, 2018 Radiant pipes in a vacuum work the best for transporting steam They may take a little damage at first but they quickly heat up and once they reach the desired temperature they never cool down due to the vacuum Link to comment https://forums.kleientertainment.com/forums/topic/98155-temperature-in-insulated-pipes/#findComment-1111448 Share on other sites More sharing options...
Xadhoom Posted November 8, 2018 Author Share Posted November 8, 2018 i'm getting so frustrated with temperatures atm... i build some liquid storage in space, fairly far from rockets, no debris at all nearby. i filled it with about -195 degree liquid oxygen. some time later, i notice that pipe breaks, weird, once i check on the storage... -60 degree liquid oxygen.... WTH!? how did it heat up more then 100 degrees in VACUM! i cant change temperature that fast surrounding it with 1000 degree steam! not whole 5000 KG of liquid oxygen!

The bottom left tile of the reservoir interacts with the tiles it's built upon - build them on mesh tiles if you're working within a vacuum and you should be fine. Same applies to refineries both metal and oil.
