OTF-1200X-HP-VIII-80-GF is a high-pressure tube furnace with eight heating zones and a pressure control system. The processing tube is made of Ni-based superalloy (50 mm ID x 2000mm L) which can withstand high pressure (oxygen or inert gases) under 1100°C max. Its pressure control system can maintain a stable pressure during the heating process which is critical for processing Fe-based superconductive material, or new generation oxide ceramics.

Process Vessel
|
- The pressure vessel is made of Nickel-based superalloy GH747 (Click to download GH747 nickel-based alloy datasheet)
- Vessel size: OD 85 x ID 50 x Length 2000 (mm)
-
Optional: torque wrench is available here to avoid over-tighten the flange bolts.
- Warning: Never put a sample inside the tube directly without crucible or isolated foil to avoid reaction to the tube.

|
|
Flange and Fitting
|
- Two CF type flanges are weld with female 1/4"NPT fitting to connect the high-pressure tube
-
2 pcs Copper o-rings are included ( spare copper O-ring is available as consumable )
|
Gas Flow & Pressure Control System
|
- Gas flow and pressure control system is built in a heavy-duty mobile table under the furnace and safety frame
- Two pressure sensors and digital displays are installed to monitor the pressure for gas inlet and furnace tube
-
One high-pressure mass flow controller is installed at the gas outlet to control the gas flow rate with max. 10Mpa working pressure and 500 SCCM flow rate
- A pressure relief valve is installed, which will release gas when the pressure reaches the setting point for safety.
|
Compliance & Warranty
|
- CE certified
- NRTL or CSA certification is available upon request at the extra cost.
- One year limited warranty for lifetime support
|
Safety Notes
|
- Ni-based Superalloy ( Waspaloy or equivalent) is a reliable processing tube, which has excellent ductility and tensile property so only creep deformation happens under overpressure before a cracking.

- Attention: For the use of flammable, toxic, or corrosive gases, you must contact the MTI engineering group for the consultation to know all the prerequisites and precautionary measures.
