Why would Russia hit Nord 1 &amp;2?

I'll give you one last explanation. You can have the last word, I value my time, and I think I have proven beyond a reasonable doubt all my assertions.

"Yeah, if the NS pipe was buried.. was it? Oh, no, it wasn't." You are the one that just provided an example of an explosion (off the ground might I add [which you also correctly explained the further you are from something the less damage it does (and to be ultra clear, when you take out the weight bearing columns on the ground floor of a building, it falls down. notice the whole building didn't fall initially, just the side where the weight-bearing columns were taken out)]) which caused a crater, so you admit regardless of what type of crater it is, (displaced/ "vaporised" (your words) an explosion over the ground can cause a crater.

"When a pipe ruptures due to internal pressure build up, it looks like this" If you think that is the only outcome of internal pressure build-ups of pipes, then you clearly know nothing about the industry. Just google natural gas transmission pipelines and how "loss of containment" occurs due to E.g mechanical failure or operational/human error (internal over pressures). You will quickly understand what safety equipment is required and what shut off valves and blow out preventers are used, for different pressurised pipes. The higher pressure you go, the more likely you will get a much more devastating rupture than what you are trying to sell me as the only possible outcome of "internal pressure build up". It's just not respectable to try to feed me with the only possible end result being the pictures you post. If you told that to anyone in the industry, they would laugh at you. The pictures you are showing is likely due from the pipes being overpressurised, however we are talking about 1200bar compared to their usual 200bar (not just slightly over).

"Theres a section of pipe missing, torn at the welds, and a crater." exactly like the video I showed you.

"Sure, there may not have been a "fireball explosion", but nonetheless, an explosive force, ie, the buildup of gas under the earth and under the pipe provided an explosive force external to the pipe." you are just making things up, and you are completely disregarding the fact that natural gas pipelines are well known to cause craters not just from "leaks" which is what you are trying to suggest, but for many reasons, some of which I have posted multiple times, e.g: mechanical failure or operational/human error (internal over pressures) [which is what the literature describes]. I understand this destroys your theory, but that is just what the scientific literature lists as potential causes of craters caused by "loss of containment" from natural gas pipelines.

"Explain to me how pressure built inside the pipe at just that section inbetween the torn welds? If the pressure inside the pipe was enough to make the entire vessel rupture, it would have destroyed the entire pipe... not just one section..." This tells me you must be young. It's an amateur question to be asking. The whole reason PIGs exist is for maintenance to prevent this exact occurrence. Corrosion, ground shifting, earthquakes, etc etc can all jeopardise the integrity of the pipeline (and to localised sections, that is why the PIG examines the shape and integrity of the pipe the whole way along), this can cause localised weak links and when the pressure does build up for many reasons, e.g human error, it will destroy the weakest part of the pipeline first. In other words: The effects of internal pressure and geometric imperfection of the pipe walls on the axial stresses and the evolution of the maximum compressive strain, at the critical pipeline section for an increasing relative axial ground deformation will result in an explosion causing a crater and or a rupture as seen in the above video:

>and I think I have proven beyond a reasonable doubt all my assertions.
You haven't. You've made an assertion and provided information that doesn't fit the events of the NS destruction.

> an explosion over the ground can cause a crater.
So, again. A 2000kg equivalent explosive, with a truck "shielding" the road (that's what - 15mm of steel plate?) digs a 2 metre hole (by vaporising the earth)
And, in your theoretical model, a 500kg explosive - with 30mm of steel plate and 70mm of concrete shielding it from the sea bed- digs a 3-5 metre hole.

I'm not understanding how less explosive power leads to more earth being vaporised.

>The pictures you are showing is likely due from the pipes being overpressurised, however we are talking about 1200bar compared to their usual 200bar (not just slightly over).

And I showed you a picture of what happens to a pipe that is destroyed with an explosive. Not what we see with NS.

So again. Force that caused the pipe to shear = external to pipe.

>exactly like the video I showed you.
Yes, and in the video you showed me...

The force
Applied to the pipe

was

E X T E R N A L

To the pipe.

It was between the outside of the pipe and the earth.

Which, again, is what happened in the NS destruction. An explosive force between the sea bed and the pipe - which is why the pipe is ripped at the welds and why there is a crater.

> you are just making things up, and you are completely disregarding the fact that natural gas pipelines are well known to cause craters
I'm not disregarding a thing. Let me be clear for you: Buried NG pipelines that leak into the earth cause craters.

Buried. Pipelines.
Buried.
Key word.
Buried.

Because when something explodes under the ground, a crater is formed.

NS - not buried.

You're making up that a crater formed due to a buried explosion is the same thing as a depression crater that forms when earth is vaporised.

Now this part is just funny

> This tells me you must be young. It's an amateur question to be asking.
Sounds like an ad hominem. Looks like I win, friendo, since you've resorted to attacking me instead of the argument.

I like this word salad part. But you're kind of right, even if you don't know what it means.
>The effects of internal pressure and geometric imperfection of the pipe walls on the axial stresses and the evolution of the maximum compressive strain, at the critical pipeline section for an increasing relative axial ground deformation will result in an explosion causing a crater and or a rupture as seen in the above video.

Let me draw you a picture to help you understand what you actually wrote.

Step 1 :
Pipe ruptures, leaking gas into the ground. The ground effectively becomes a part of the pipeline.

Step 2: Pressure builds up to the point that the earth can no longer contain the gas pressure, causing an explosive rupture of the earth - ripping the pipe from its welds. The earth underneath the pipe basically exploded like a balloon. "Axial ground deformation".

Which applies a force to the pipe.. thats... external... to the pipe.

.
Further evidence : heres the remains of the pipe, note how it's all in one section? Because the pipe did not explode. The gas pressure that leaked out of the rupture pushed it out of the earth.

Again. The crater occurs for one reason only : The explosion occurred underground.
