The design temperature is 900°C, the design pressure is 4 Ma, and the medium is air – what pipe material should be chosen? I seek advice from experts.
The 2520 model can reach 1150 degrees in temperature, but with such high pressure, it’s likely to be a challenge. The highest value in the pressure-temperature rating table is 816 degrees, but the allowable operating pressure at 2500 LB is only 14.8 bar; this means that only very rare and special nickel-based alloys might be suitable, and it’s unlikely that any alloy can handle such high pressures.

Could jacket cooling be considered?
I checked ASME B31.3 and GB 20801; only nickel and its alloys can withstand such temperatures, but there is no relevant project experience available
What material can be used for the lining to withstand such high temperatures?
You must be joking with me – can Q235 be used at such high temperatures and pressures?
Nickel-based materials – I wonder if those who work on boilers know about them?
