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.
