Ultra-high pressure tube. .

4\" steam pipe. Is the control valve large or small? ! ! ! !
So many stainless steel pipes are used here; where on earth is this? .
It is alloy steel with an insulating layer on the outside. . .
Could you tell me what material it is made of? Where is it used?
The operating temperature is 500 degrees, and the pressure is 200 BAR; during testing, the pressure was increased to 380 BAR.
German-made P91 alloy steel is being used in a steam pipeline of a turbine! !
Is 200Bar considered ultra-high pressure? The highest design pressure for the pipes I’m working on now is 15,000 psi (1034 Bar), with a test pressure of 1.5 times that value… I’m quite worried; could the original poster provide some information on the installation procedures?
Hm? I’ll help you look for it. .
This is also considered a ultra-high pressure pipe; those used for ultra-high pressures are made of high-carbon steel, and the flanges cannot be welded – they must be connected by threads. We use 4200 BAR.
This test isn’t difficult, right? Oil pressure is sufficient. If your oil pressure pump is small, make test connections, install needle valves, and test them one by one. If you test the entire system, you can use your process pump directly. We have reached 6000 bar many times. It’s not difficult at all. It’s just dangerous; be careful and that’s it.
