Process Vessel |
-
Made of Nickel-based superalloy GH747(Click to download GH747 nickel-based alloy datasheet)
- Size: 85 mm OD x 50 mm ID x 1000 mm L
-
Working gasses: O2 and inert gasses such as N2, Ar, and He
- Small quartz or alumina boat should be used to load the sample inside the tube. Never place the sample directly onto the tube without a crucible, which may greatly shorten the processing tube service-life
- Warning: Never put the sample inside the tube directly without crucible or isolated foil to avoid sample react with tube alloy.
- You may use gold or nickel foil to wrap the crucible to minimize the contamination to the pressure vessel.
- Attention: The processing tube is consumable. Pls click the photo below to order a spare one

Pressure Sensor and Valve
|
-
A pressure gauge with a range of 0 – 25 MPa and an over-pressure alarm is installed (downstream side)
-
A pressure control valve with a working range of 0.2 – 15 MPa is installed (the upstream side with a 1/4" BSPP venting port)
-
If the measured pressure reaches the high-pressure alarm value, the pressure control valve will be opened until the pressure drops 0.2 MPa (2 bars) below the alarm value
- The manual pressure relief valve is installed for manual pressure control and relief (the downstream side with 1/4" BSPP gas outlet port)
|
High-pressure relief valve
|
- A safety pressure relief valve is recommended (the upstream side with 1/4" NPT venting port)
- Please info us of your application temperature and we will pre-set the release pressure for you. For example, you need to heat to 800C, the Max working pressure should be 140 bars, we will pre-set the relief valve to 140 bars.
|
Flange and Fitting |
- A pair of 63 mm CF-type flanges are included. Please use a torque wrench (optional, not included) to avoid over-tightening the flange bolts.
- 2 pieces of copper O-rings (99 mm OD x 82 mm ID x 2.2 mm thickness) are included. Please order extra copper O-rings as consumable parts
- A pair of cooling fans are included for air cooling the flanges
- One mobile cart with installation holes is included for easy setup and immediate use

Optional Parts
(with extra cost)
|
- Please order heavy-duty rotary vane vacuum pump EQ-YTP-50 for low vacuum operation (Pic #1)
- If a high vacuum is needed, please use the turbopump station – EQ-PV-HVS2 (Pic. #2), which can reach 10-6 torr vacuum
- Gas flow control system is available upon request (Pic. #3)
- Please use a torque wrench (optional, not included) to avoid over tightening the flange bolts (Pic. #4)
-
To measure the electric properties of thermoelectric ceramics under high pressure & high temperature, please order alumina fixture and high-pressure electrical feedthrough (10 MPa max) with the furnace at extra cost (Pic. #5 & #6)
