Laboratory High-Temperature High Pressure Tube Furnace

Laboratory High-Temperature High Pressure Tube Furnace

Introduction:

The HP1200 Mini High-Temperature High-Pressure Tube Furnace is equipped with a high-pressure solenoid valve, pressure sensor, and analog safety protection on the flanges. With up to triple safety protection, you can work with peace of mind. When the pressure inside the chamber exceeds the set value, the solenoid pressure release valve automatically opens to vent the gas, maintaining the pressure inside the tube at the desired level. This furnace allows for heat treatment of samples in a high-pressure gas atmosphere, with a maximum temperature of up to 1150°C, making it suitable for research in superconducting and dielectric materials.

Features and Benefits of High Pressure Tube Furnace:

1. Triple safety protection ensure peace of mind during operation.
2. High circular heater ensures uniform temperature distribution.
3. Modular design for durability and ease of maintenance.
4. Stabilized pressure setting for safety and reliability.
5. Simple one-touch operation with 15 pre-stored work curves for flexible use.
6. Real-time monitoring of sintering temperature and power consumption, ensuring safety and energy savings.

Technical Parameters of High Pressure Tube Furnace:

Model	HP1200-2350TIY-D
Power Supply	AC220V   1.5KW
Temperature and Pressure Allowance	The maximum allowable pressure is dependent on the temperature, as shown in the table below: Furnace Temperature Maximum Chamber Pressure ≤ 600°C ≤ 24MPa ≤ 800°C ≤ 20MPa ≤ 900°C ≤ 12MPa ≤ 1000°C ≤ 6MPa ≤ 1100°C ≤ 4MPa High-temperature and high-pressure tube is consumable. Please replace it promptly if any deformation is observed.
Chamber Specifications	1.      Dimensions: Sample constant temperature zone Φ23mm *120mm (custom sizes available upon request). 2.      1/4NPS internal threaded interface installed at the furnace tube gas inlet, with matching high-pressure gas supply tube. 3.      The high-temperature and high-pressure furnace tube is made of high-temperature alloy steel, with a TMAX of 1150°C and good ductility.
Furnace Structure	1.      Double-layer structure with an openable design, suitable for customers requiring rapid cooling, with a shell surface temperature of less than 60°C. 2.      The inner furnace chamber surface is coated with a nano high-temperature alumina coating to improve heating efficiency. 3.      The furnace body is designed to be openable for easy loading of materials and replacement of the furnace tube.
Gas Compatibility and Crucible Use	1.      Compatible with oxidizing, protective, and inert gases such as N2, Ar, and He. 2.      To avoid sample contamination, it is recommended to wrap the sample in gold or nickel foil and place it in an alumina or quartz boat before inserting it into the furnace tube for sintering. Do not place samples directly in the high-temperature high-pressure tube without a crucible.
Control System	1.      The system can store up to 15 temperature curves, each with up to 30 segments of “temperature-time” axes, avoiding the hassle of resetting different experimental processes. 2.      The embedded operating system features a bilingual (Chinese-English) graphical interface with a 7-inch true color touch screen, intelligent human-machine interaction, real-time heating power display, and nonlinear temperature correction. 3.      The system includes over-temperature, over-pressure alarms, thermocouple protection, leakage protection, and differential pressure release functions. 4.      Triple safety protection: First: The solenoid valve automatically releases pressure when the pressure exceeds the customer-set value. Second: If the exhaust line is blocked or the solenoid valve is damaged, causing the pressure to exceed the release value, the system will automatically stop heating when the pressure reaches the system’s preset maximum pressure. Third: If the digital sensor is contaminated or the program control system malfunctions, causing pressure to continue rising, the safety analog signal pressure relay will cut off power when the pressure reaches the preset upper limit.
Temperature Accuracy	+/- 1℃
Dimensions and Weight	800 x 450 x 350mm   45KG
Heating Element	Molybdenum-doped iron-chromium-aluminum alloy
Pressure Detection and Control	1.  The high-pressure chamber is equipped with a pressure sensor connected to the control system, displaying real-time pressure. 2.  A high-pressure relief solenoid valve is installed on the flange. When the internal pressure exceeds the set value, the solenoid valve automatically opens to release the gas, maintaining the chamber pressure within the set range. The maximum pressure the solenoid valve can automatically relieve is 15MPa. When using pressures above 15MPa, do not use the solenoid valve to relieve pressure; instead, close the series needle valve and manually relieve the pressure.
Flange Sealing	The CF flange structure diagram is as follows. 1/4NPS internal threaded interface installed on the furnace tube flange, with high-pressure valves installed at both ends of the flange. The right valve is equipped with a pressure gauge. The flange is sealed with oxygen-free copper rings. A torque wrench can be purchased to avoid over-tightening the flange.
Service Support	1-year warranty with lifetime support (warranty does not cover consumable parts such as furnace tubes and sealing rings).
