Please email for lead time
Item Number: OTF-1200X-VIII-80-GF

OTF-1200X-HP-VIII-80-GF is a high-pressure tube furnace with eight heating zones and 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.

SPECIFICATIONS

    Thermocouple

    Process Vessel

    • 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. Please click the image on the left to order.
    • Warning: Never put sample inside tube directly without crucible or isolated foil to avoid sample react with tube alloy.
    Working Pressure
    • 20 Mpa max. at  <800°C
    • 13 Mpa max. at <900°C
    • 6   Mpa max. at <1000°C
    • 4   Mpa max. at <1100°C
    • Never heat up above 1200°C

    Working Gases
    • Inert gas and oxygen
    • No hydrogen or any flammable gas
    Flange and  Fitting
    • Two CF type flanges are weld with female 1/4"NPT fitting to connect 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 gas flow rate with max. 10Mpa working pressure and 500 SCCM flow rate 
    • Pressure relief valves are installed to ensure safety. The valve will release gas when pressure reaches setting point.

                             ( click mark to learn what is )
    • One year limited warranty for lifetime support
    Application Notes
    • Hytort Application, or named Hydroretorting of Shale Oil is a process developed by IGT to double the yield of shale oil and hydrocarbon gases. MTI High-Pressure furnaces with Ni-based superalloy tube is an ideal tool for conducting related experiments. Please click underlined to view research paper.
    Safety Notes
    • Ni-based Superalloy ( Waspaloy or equivalent) is a reliable processing tube which can be used under high temperature and high pressure.. It has excellent ductility and tensile property so only creep deformation happens under overpressure destruction test and following by a crack formed (usually at the hot zone at the center of tube) to release the pressure. Brittle fracture won’t happen in the overpressure destruction test which means no tube explosion will happen under overpressure of inert gas or safe gas or under other accidents causing overpressure of inert gas or safe gas.

    • Attention: For the use with flammable, toxic or corrosive gases, you must contact MTI engineering group for the consultation to know all the prerequisites and precautionary measures.
    • AttentionA two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Please click here to learn how to install the gas regulator.
