Searching for Material that will cope with 2600F temp.

Searching for Material that will cope with 2600F temp.

Searching for Material that will cope with 2600F temp.

(OP)
I work in a refinery that 'Roasts' ore. I am searching for a material that will cope with 2500 degF - 2700 degF temperature to use as our burner telltale tube. We had used 310 stainless steel but it could not cope with the constant high temperature. Can anyone recommend a material that we can source in a pipe shape that may cope under these conditions. Thanks.

RE: Searching for Material that will cope with 2600F temp.

There is no metal that will work. There may be a ceramic material that would work.

RE: Searching for Material that will cope with 2600F temp.

TZM (Titanium-Zirconium-Molybdenum alloy) is rated up to 1400°C - it may just work in your case.  One supplier is PLANSEE (see www.plansee.com)

Is pure tungsten not a candidate? Just curious.

RE: Searching for Material that will cope with 2600F temp.

I have used refractory metals, I would suggest that you look at ceramics.

Without coating the refractory metals will all oxidize at that temp. Diffusion coatings on refractory metals may provide the life expectancy required. These have been used in rocket engines.

I would go with Ed's advice and look at ceramics.  

RE: Searching for Material that will cope with 2600F temp.

you will also need to characterize the hot gases' content of sulphur , sodium, mercury, etc since some of these elements  ( in a reducing atmosphere) may attack some ceramics.

RE: Searching for Material that will cope with 2600F temp.

Ceramics formed using Polysilazanes (an inorganic polymer) might be a way. I have seen some performance data at 1500C.

Try Kion Corp.

They don't make ceramics, they make the silazane and can probably say one way or the other.
