High Temperature Tubing 1

[ME231]

Hello All,
Could anybody please point me towards some tubing material that might take some pressure at around 1000C (1800F)?
I know its a tough call, but I wanted to consult with the vast knowledge base that we have available here before calling it quits.
Thanks in advance for any help on this.

Hint;
Get your hands on a copy of ASME B&PV Code, Section II, Table 1B.

Material
ASME SB 167 UNS N06617

thanks a lot for your tip metengr!
I was aware of alloy230 tubing - this stuff is twice as strong at 1800F!
thanks again.

There are cast HP Modified and 35Cr-45Ni alloys that are commonly used in Olefin plants.

The smallest cast tubes you're going to get are several inches in diameter, so those materials stanweld mentioned are probably not what you're looking for.

230 is an obvious choice, as is 800HT though you may be beyond the highest temperature that stress values are listed for it. It is widely avaiable, being used as an electric heating element shell tube.
