Stress Corrosion Testing Machine

Equipment Introduction

• Slow strain rate stress corrosion testing machine is used in the corrosive medium environment for measuring the corrosion tensile test. The host machine structure is adopted frame type; the loading unit can upside down and fixes in order to meet the different medium environment’s testing requirement.
• The medium environment can be connected has: high temperature and high pressure pure water (temperature 0~650, pressure 0~35MPa), the salt water environment with trace alkalinity or acidity, also can be used in high concentration medium corrosion environment such as: NaOH, Na₂CrO₄, N₂O₄, HNO₃, NH₃OH, H₂S, CO, CH₄, Cl solution, methanol, organophosphate hydraulic oil, CH3COOH etc. Some medium’s concentration reach a level ppm, then need to consider the working life of the experiment caldron.

Equipment feature

• High rigid overloading framework
• High performance digital servo load control system, the speed control accuracy is high.
• Can use double transformation sensor, specimen’s transformation measurement accuracy is high.
• Pressure-balanced system, can equip water cooling system.
• Integrated form AEC-1800 measurement and control system, it’s convenient to extension.
