  OTF-1200X-HP-55 is a split tube furnace with a Ni-based super-alloy tube (55mm O.D x 20 mm I.D x 600 mm L) and flanges/valves. It is designed for use at high pressure (7 MPa) up to 1100°C under oxidizing and inert gas atmospheres to process special compounds. It is an ideal furnace to use for preparing new materials under high pressure and also can be used as a mini HIP to treat metallic samples. ( Laptop is included since 9/10/15 )

Pressure Sensor and Display
  • Precision high-pressure sensor (Pressure measurement range: 0~25Mpa) installed on the pressure vessel.
  • The pressure sensor is installed in the flange. The pressure will be displayed in the pressure controller in the front panel of the furnace.
  • The alarm system is built in the pressure controller which allows the user to set up the high and low limit points of pressure. When the measuring pressure exceeds the limit point, the alarm strobe and whistle will be activated for the warning.
  • When the pressure reaches the alarm set point (Max.15Mpa), the pressure inside the vessel will be released via the solenoid valve installed on the flange.                                                                               For Max. pressure >15 Mpa, please shut off the manual needle valve
  • Optional: Adjustable High-Pressure Relief Valve 1000 - 10,000 PSI (7 - 70 Mpa), click the picture below right to order.

Pressure Fitting
    • One Super-alloy flange is included.
    • One Aluminum heat radiators are installed in front of the flange to keep the flange below 100
    • A high-temperature pressure transmitter, MTI-ZQ-GW is pre-installed with a flange
    • One solenoid valve(Max.15Mpa) is pre-installed.
    • The safety pressure relief valve is installed on the downstream side.

    • You may order four Pt wire ( 0.35 mm dia ) feed-throughs to install the furnace for measuring material electric conductivity under high pressure up to 1100oC at extra cost.
    • 10 mm Sapphire window can be installed on the flange for the Ramman beam under high pressure at extra cost ( click the picture below right to see details)
    • To measure the electric properties of thermoelectric ceramics under high pressure & temperature conditions, please order an alumina testing fixture and high-pressure electrical feedthrough (10Mpa Max.) with the furnace (additional fee will apply).

        Safety Notes

    The picture shows a Ni-based Superalloy ( Waspaloy or equivalent) processing tube under an overpressure test.
    • Ni-based Super-alloy ( Waspaloy or equivalent) is a reliable processing tube that can be used under high temperatures and high pressure. It has excellent ductility and tensile properties so only creep deformation happens under an overpressure destruction test followed by a crack formed (usually at the hot zone at the center of the tube) to release the pressure. Brittle fracture won’t happen in the overpressure destruction test which means no tube explosion will happen under
    • Attention: For the use of flammable, toxic or corrosive gasses, you must contact MTI engineering group for a consultation to know all the prerequisites and precautionary measures.
    • Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure. Click here to learn about the installation of a gas regulator.
    • Do not over-tightening the flange screws as this may cause permanent damage to the flange or screws. Please refer to the instructions about proper torque for installing CF flange bolts. We recommend you use a torque wrench to tighten the screws with the flange.
    • Warning: Never put a sample inside the tube directly without a crucible or isolated foil to avoid sample reaction with tube alloy.
