Big tank pressure regulator ?

[[Taurus]Ateros]

Here i am once again but this time i cannot find something that will equalize the pressure for BIg tank because the Pressure regulator can only do 20kpa max and big tanks support 50kpa so is there something that can do same as the regulator but for big tank ? thanks

volume pump ideally working alongside a pipe analyzer.

I've also been known to use a digital valve and use my tank control IC circuit to open/close when pressure meets a specific threshold.

A suggestion I have on devices posted here, feel free to lend a voice.

I was under the impression that the pipes are the limit for both the small and large tank.
Pipes burst at ~60MPa.

I just have a passive vent with a digital valve hooked up to some logic to read the tank/pipe pressure and activate the valve when the pressure is above 48MPa.

[JeanDeaux]

Pipes do have a limit of ~60Mpa while in a vacuum, but with an outside air pressure they can hold more, I'm not sure it's a 1:1 ratio but the jist of it is if you have 10Mpa outside air pressure then your pipe pressure can now hold ~70Mpa.

I am thinking that the 0-100Mpa range would accommodate those that want to push the limits and allow some room for players to hang themselves if not paying attention to what they are designing. Think Kerbal Space Program, they give us rope, we hang ourselves.

I did some logic circuitry that is set up in terms of "If pressure is less than 50mpa turn volume pump on" so via pipe analyzer if it reaches 50mpa greater it turns pump off thus blocking the input to large tank

A good first step, but it's a half measure if you have temperature variances to take into account. If your gas temperatures rise, then pressure will end up increasing and you may need to vent out gas that was once within pressure ranges that are now risking that safety margin. If you've got temperature controlled then nothing to worry about, else you'll appreciate having that safety bleed valve to prevent having to rebuild a good portion of your base.

shhhhhhhh, explosions are great learning tools... *evil giggle*

First of all i'd like to state that I am very much NOT experienced and knowledgeable in the game. That being said, my usual go-to measure when (if) my bases start becoming big enough to warrant storing vast quantities of gas, is to use a cascading array of tanks, preferably insulated (and also using insulated pipes) or placed in a cool environment that fill one after the other when each one approaches critical pressures. I try never to pressurise any tank beyong 50MPa simply as a safety measure as well.
So when a storage pipe network (with all included tanks and all) reaches about 50MPa another tank is connected to the network, initially via a back-pressure regulator that is later replaced by digital valves, once I get invar made. The tricky thing, early on, is to carefully design the network so you can read pressure from the tanks until you produce electrum for the pipe readers, without having parts of your piping that may be over-pressurised to bursting points by accident or neglect. For fuel mixes I also usually set a temperature alarm.
If I'm unable to build an extra tank as a safety measure I just place a passive vent after the whole logic chip-digital valve assembly. Yep I haven't gotten around to learning IC10 programming and I use simple logic I/O's and processors, which, tbh for this setup are usually enough. I don't know if it is worth the trouble and resources to set up an IC10-controlled system, I have no experience with it so I can't say.
As a funny side note, I haven't learned this or fallen to this routine just by having stuff explode though. At least not too many times. I'm an actual engineer but initially I didn't "read the manual" i.e. the F1 menu, to check for max tolerances etc. Then I decided to stop trying to learn the game by playing and run the tutorials first instead :D
My engineering skills leave much to be desired, what can I say :D

I hope the following code will help you.
The following code is used to prevent the tank from exploding due to overpressure when the pressure in the tank exceeds the maximum pressure set.
(The reason I post the code here is because for some reason I can no longer share the codes or save files.)
Number 1 is controlled centrally.
Number 2 is controlled by each Filtration .
Finally, for excess pressure, post-processing is considered to be the right processor rather than pre-processing personally.

Ugh thats long reply XD ... so i apreciate the code for IC i kinda was digging into IC just with xor , or gates and solar tracking this can come in handy thanks
