Product Description

The high-temperature high-pressure tube furnace is a precision-engineered device designed for advanced material synthesis, thermal treatment, and reaction experiments under extreme conditions. It integrates state-of-the-art thermal control, pressure containment, and corrosion resistance, making it ideal for research laboratories, universities, and industrial R&D applications. This system is especially suited for applications involving gases or vapors at elevated temperatures and pressures, such as gas-solid reactions, thermal decomposition, catalyst testing, and advanced ceramic or alloy processing.
The central feature of the furnace is its high-quality stainless steel tube, typically made from 304 or 316L grade stainless steel, depending on the pressure and corrosion resistance requirements. The tube is polished both internally and externally to reduce contamination and ensure uniform gas flow. Its structural integrity allows it to withstand pressures up to 10 MPa or more and temperatures up to 1100-1300°C, depending on the insulation and heating element configuration.

The heating system consists of resistance wire or silicon carbide elements uniformly distributed around the tube to provide precise temperature control and excellent thermal uniformity throughout the heating zone. A high-performance insulation layer minimizes heat loss and maximizes energy efficiency. The tube is usually supported on both ends with flanges that incorporate high-pressure seals, allowing for easy connection to gas supply systems, pressure gauges, safety valves, and cooling systems.
Temperature is regulated via a programmable PID temperature controller with multi-segment ramp/soak functionality. Real-time temperature monitoring is achieved using high-precision thermocouples (e.g., K-type or S-type), which are inserted near or into the furnace chamber to ensure accurate readings. Safety features such as over-temperature protection, automatic power cut-off, and emergency pressure relief are standard to ensure operator safety and protect the furnace system.
To meet high-pressure application requirements, the entire assembly is housed within a pressure-rated shell and often includes external cooling systems-such as air or water cooling jackets-to maintain mechanical stability and prolong equipment life. Optional configurations may include vacuum pump interfaces for vacuum-assisted heating, gas flow meters and mass flow controllers, and data acquisition modules for real-time monitoring and control via computer or PLC interfaces.
This type of tube furnace is widely used in advanced research fields including material science, energy storage, environmental engineering, metallurgy, and semiconductor processing. Whether conducting hydrogen reduction, sintering under inert gas, or performing solid-gas reactions under controlled atmosphere, the stainless steel tube provides the durability, pressure integrity, and chemical stability required for demanding experimental conditions.

In conclusion, the high-temperature high-pressure tube furnace with a stainless steel tube represents a versatile, reliable, and high-performance solution for modern thermal processing. Its robust construction, precise control systems, and customizable options allow researchers and engineers to simulate and analyze a wide range of high-pressure, high-temperature processes with confidence and accuracy.
