Why aren’t vacuum tubes used for liquid oxygen pipelines?

All the liquid pipes in my tower are vacuum tubes, of XX brand, and no problems have occurred despite years of use. Some people have mentioned the issue; it seems that the system wasn’t properly set up when it was put into use. It should work fine during normal operation, so just proceed slowly when starting it up. It’s just an insulated liquid pipe – what could possibly go wrong? . .
We wanted to use vacuum tubes, but it didn’t work out; the main reason was that it would be troublesome to modify them in the future
There have been many explosions in liquid oxygen vacuum tubes… That’s why many manufacturers in China no longer use such tubes; however, the quality of imported tubes is indeed better. We also use vacuum tubes for liquid oxygen, but the new storage tanks use stainless steel tubes with insulation layers, as the management is worried about similar explosions occurring…
Gentlemen, what are the dangers of vacuum tubes for liquid oxygen, and what causes them to explode?
Hydrocarbon accumulation is likely to occur; basically, explosions happen at the valves... Hydrocarbon accumulation is likely to occur, and basically explosions take place at the valves…
So now, with stainless steel pipes, there is no hydrocarbon accumulation at the valves? Could there be other reasons for this? What is the insulation material inside the vacuum tube? Is it a true vacuum?
Our company uses vacuum tubes for its liquid oxygen pipelines, and no problems have arisen
1. Bellows are used for the compensation of vacuum tubes, but their thickness generally does not meet the required standards; leakage is likely to occur if they are in use for a long time； 2. There are often flammable materials in the vacuum tube interlayers ； 3. When the vacuum tube compensator leaks, oxygen will leak into the interlayer, posing a risk of physical and chemical explosions
Space shuttles are at risk of exploding; can humanity’s pursuit of exploration not continue?
That makes sense, haha. I’ve learned from you; thank you. I’ll keep learning from all of you experts in the future*
