High Pressure Tube Furnace with 20mm ID. Super-alloy Tube up to 1100C @ 700PSI- OTF1200X-HP-55-UL

OTF-1200X-HP-55-UL is a split tube furnace with CE/UL/CSA certified electrical components. Ni based super-alloy tube (55mm O.D x 20 mm I.D x 600 mm L) and flanges/valves. It is designed for using at high pressure (7 MPa) up to 1100°C under oxidizing and inert gas atmosphere to process special compound. It is a ideal furnace to use for preparing new materials under high pressure, and also can be use as mini HIPto treat metallic sample. ( Laptop is included since 9/10/15 )

    Safety Notes

    pics show Ni based Super-alloy ( Waspaloy or equivalent) processing tube under overpressure test
    • Ni based Super-alloy ( 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
    • Please never use ordinary SS tube to connect to gas-inlet for using > 5Mp pressure, whcih may cause tube exploded.
    • 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.
    • Attention: A two stage pressure regulator must be installed on gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
    • Do not over tightening the flange screws as this may cause permenent damages to the flange or screws. Please refer to the instructions about proper torque for installing CF flange bolts.We recommend you use torque wrench to tighten the screws with the flange.
