best material to keep pipes from breaking?

[Denisetwin]

Pumping hot water to anti-entropy cooling I have set up, cannot keep the pipes from breaking right before they go in the pool under the setup.  Tried granite, tried abyssalite, tried insulated abyssalite, what's the secret?

thanks

Pipes break for 2 main reasons.  A phase change in the pipe (gas to liquid, liquid to gas, liquid to solid) or the new "constantly breaking for no apparent reason" bug.

The bug can usually be fixed by reloading and then deconstuc and rebuild that section (you have to be sure to reload though).

Phase changes need to be prevented by fixing whatever is changing temps enough to cause a phase change.

No pipe material is stronger than another.  When the material inside changes state, the pipe will break.  If you don't want your pipes breaking, you will have to get it out of the pipe before the state change or avoid the state change altogether.  Sounds to me like your pipes are freezing.

Yup, if you have water going near the thermo Nullifier the water inside will drop in temperature. and as you surely know, water freezes at 0°C, with at this point breaks the pipe and drops ice right below where it breaks.

Hmm, I will check again, but the water in the pipe is at 26 degrees or higher, I don't think it's freezing the pipe.  The pipes are very cold, but the water inside using the tooltip to check is not. The pipes out have even colder water, 10c or lower and they never break.  I wonder if it sits in there sometimes and maybe goes lower.  I may have to just sit and watch it for awhile.

Are your pipes full, or do you send liquids through it in batches? Because if you send it in batches, there might be a very small packet (a few grams) at the start or end of such batch occasionally and that can then change temperature rapidly and freeze solid, breaking the pipe even though it doesn't happen with full 10 kg packets.

By the way, the entropy nullifier is way too weak to provide liquid cooling. AFAIK its output is about 32 kW of heat destruction (about three wheezeworts) which is enough to cool a single 10 kg packet of water by 0.75 C per second. So if you put a meandering pipe in front of it and send water through that pipe, it will be on average 0.75 C colder on output as every second one 10 kg packet enters the loop and one exits.

Yes, AETN is weak for liquid cooling, but I thought it was 80kW; did it get nerfed? Listed 400W * 200 hidden multiplier = 80kW

It works great for me, I run my sleet wheat farm off it and get constant 8 to 10c water, but I do not have pipes running through it, I'll take a screen shot tonight, I use automation to put water into a very small pool underneath it, I have the area full of carbon dioxide, the AETN keeps the carbon dioxide constantly liquifying, it drops off the AETN ledge and into the water I want cooled, I use hydro sensors to make sure the water does not come in contact with the ledge otherwise it doesn't get cold enough.  Someone can probably improve on it, I'll post the screenshot tonight.  The only issue I've had is the pipes leading to it.  I'm thinking if I move the water shut off valve further away from the AETN and adjust the hydro sensor to account for the last of the water draining past it instead of an immediate stop, that may help, hopefully.  Otherwise the issue is the smaller packets that @Kasuha says and I don't know how to solve that.....
