Don’t you just hate it when you’re building a pipeline and your mouse skips a few pixels and you end up with kinks?
The pipes would warp and break without those extra loops. They mitigate contraction and expansion due to temperature changes.
It’s comments like this that keep me on Lemmy. It’s deeply appreciated that people with random, specific knowledge surface in the comments to answer questions that are hard to search for answers to.
This but also mitigation for hydraulic transients. Any change in flow will result in wave forming which would propagate and increase in intensity. These “kinks” are there to break it up. This phenomenon is the basis for hydraulic ram pump.
And now we know. Thank you!
That’s why all my pipelines are just pairs of pipe-to-ground every 10 tiles
Forgot to remove a tiny bush and now it’s being autorouted around
Fuckin’ finally. Took long enough.
Now go lower.
Fuck russia.
Fuck Putin.
Fuck the Russian government.
Fuck the Oligarchs too.
Fuck Musk and other lapdogs.
Isn’t this basically the same situation that ultimately led to the fall of the USSR? A fall in oil and gas revenue which led to a financial collapse. Paired with some unrest. Has Putain read the history he lived though?
Russian oil revenues are at near record highs though so we’re still a long way from any kind of collapse.
As far as I know, the USSR collapsed because Gorbachev’s reforms weakened existing institutions and power structures, without providing replacements.
That is definitely a part of it. Collapse is not caused by a single event. If I remember correctly (not 100% on my timeline without looking it up) the reforms of Gorbachev were caused by already existing unrest that in part was caused by a loss of state income. When the state provides all and has no money…
You know the Afghan war and the loss of working age men, plus the high level of support the USSR gave its satellite states, were not helpful either. Lots of factors, but when you have no money everything is worse.
The best description of Russia and the USSR before that is a Gas station with an army. That is how important petroleum is to Russia
Honestly, fair enough.
Afghanistan and Chernobyl bled the USSR dry of money and people.

Be careful the Canadians might get angry and by angry ask you nicely to not insult their native dish.
Where no one is going to care if I call him a puta
With a government relying for a substantial part on income from such an industry, any collapse of that industry will be a serious problem. Especially in a time where they need each and every ruble (or dollar, if they can get them).
Unfortunately all oligarchs have enough money stashed away abroad to not feel anything. The real fun will start once the backs of camels start breaking. Russias demise is not going to be linear and fuck them tbh.
I’m not sure they’ll be able to contain a determined uprising given how the Russian police force is in crisis due to pay so low that one is better off working as a taxi driver. And I imagine that many unpaid soldiers won’t be feeling terribly loyal if things really go to shit.
Russia isn’t producing less because of some domestic calamity that is preventing them from pumping more oil, they’re doing it because if you keep supply low and the demand remains fixed, prices increase.
anyone know why the pipelines in the thumbnail photo make those squared shapes at regular looking intervals?
In addition to the expansion loops, the straight sections of pipes are probably not even attached to the supports to allow large sections of the pipes to move, transferring the movement to the expansion loops.
https://en.m.wikipedia.org/wiki/Trans-Alaska_Pipeline_System
The trans-alaska pipeline has whole sections built on special skates to reduce the chance of damage from earthquakes (see “Construction” section).
It also merely rests on its supports to allow for expansion (see “Technical Details” sections).
In fact, the trans-alaska pipeline changes in length by 5 miles over the course of the year, and was built 11 miles too long to account for this.fuck yeah dude thats the kind of knowledge im looking for
Wow, 5 miles is insane…
If you can find it and you enjoy this sort of thing then try to track down the TV series “Worlds Toughest Fixes” from National Geographic. It ran for about 3 years and followed a professional rigger that helped out with all manner of big/difficult engineering jobs. One of the episodes involved replacing a faulty valve on a section of the Alaska Pipeline.
Thank you, I love gaining random and interesting knowledge that will likely never be of use to me. It’s really fun!!
Possibly expansion relief? They get some pretty wild temperature swings.
That’s my guess too
That’s correct
The pipes would warp and break without those extra loops. They mitigate contraction and expansion due to temperature changes.
I’m not 100% sure, but I think they allow the pipe to flex when it expands and contracts instead of breaking
If nobody got Russia’s back 😤
I know OPEC got Russia’s back 🙏
This is the best summary I could come up with:
Since Vladimir Putin’s full-scale invasion of Ukraine started on February 24, 2022, sanctions have sought to isolate Russia from the global economy, cutting it off from the SWIFT international banking system and freezing some of its foreign exchange reserves.
The Gazprom report said that the West had contributed to the decrease of the fuel and added that “the adoption in a number of countries of politically motivated decisions aimed at abandoning the import of Russian gas.”
Independent Russian-language news outlet Agentstvo reported that Gazprom “has never had such a low production rate in its entire history” and that “the last time there was similar figure was in the Soviet Union in 1978,” a year when 372.1 bcm were produced.
In February 2023, Putin accused the West of direct attempts to try to hinder and restrain Russia’s gas industry but added that Gazprom “is moving forward and launching new projects.”
Thomas O’Donnell, a Berlin-based geopolitical analyst, told Newsweek that Putin had cut gas flows, even before the attack in September 2022 on the Nord Stream pipelines between Russia and Germany—an act of sabotage that the Kremlin denies responsibility for and which is still being investigated.
Gazprom head Alexei Miller will join Putin during the Russian president’s visit next month to China to boost trade ties and offset losses of gas sales from the lucrative European market, Reuters reported.
