The high-temperature water–oxygen corrosion testing system is primarily used to evaluate the corrosion behavior and performance of materials under conditions of elevated temperature, aqueous environments, and the presence of oxygen. This testing system can simulate the corrosive conditions that materials may encounter in real-world industrial settings, providing critical data to guide material selection, design, and optimization. The following is a detailed description of the system’s main applications and functions:

Main Uses

1. Corrosion Resistance Assessment of Materials:

- By bubbling oxygen into a high-temperature aqueous environment, the corrosion conditions of the material under specific operating conditions are simulated to evaluate its corrosion resistance.

- The system is capable of bubbling oxygen into the water and precisely controlling the dissolved oxygen concentration to simulate oxygen levels under various corrosion conditions.

3. Adjustable experimental parameters:

- Users can configure experimental parameters such as temperature, pressure, oxygen concentration, and water flow rate as needed to meet the testing requirements of different materials.

4. Data Collection and Analysis:

- The system is equipped with data acquisition and analysis software that can record parameters such as temperature, pressure, and dissolved oxygen concentration in real time during the experiment, and process and analyze the data to obtain key information such as the corrosion rate and corrosion morphology of the material.

5. Security Assurance Measures:

- The system typically features a double-shell structure and is equipped with safety measures such as an air-cooling system, over-temperature protection, and over-pressure protection to ensure the safety and stability of the experimental process.

In summary, the high-temperature water–oxygen corrosion testing system is an indispensable piece of equipment in the fields of materials science and engineering, playing a crucial role in enhancing the corrosion resistance of materials, extending their service life, and ensuring the safe operation of industrial equipment.

The high-temperature, high-pressure water–oxygen corrosion testing system simulates a high-temperature, high-pressure aqueous environment, thereby providing test conditions that closely resemble real-world operating environments for corrosion measurements. Such systems are primarily used in materials science, petrochemical engineering, power plant boilers, and nuclear power steam generators. In particular, under high-temperature, high-pressure water service, the concentration of corrosive impurities often leads to widespread corrosion of heat-transfer tubing. By employing this testing system, it is possible to evaluate the corrosion resistance, corrosion behavior, and corrosion mechanisms of materials, thus providing a scientific basis for material selection and application.

In addition, the high-temperature water–oxygen corrosion testing system uses pure water as the test medium, enabling the measurement of dissolved oxygen, pH, electrical conductivity, and other parameters in the test loop, as well as the precise control of circulating water temperature and pressure. This system can also be integrated with a slow-strain-rate stress-corrosion testing machine to conduct tensile corrosion tests under controlled stress conditions, thereby facilitating more in-depth investigations into the corrosion behavior of materials under specific environmental conditions.

In summary, high-temperature water–oxygen corrosion testing systems play a crucial role in materials corrosion resistance research and applications by simulating real-world operating conditions, thereby providing a scientific basis for material selection and optimization.
