一手提式慢应变速度应力腐蚀试验装置手提式试验装置是用来测定动态介质中的应力腐蚀开裂特征,该装置可在实验室、工厂和压力小于13.8MPa(2000Psi),温度低于204℃(400°F)的现场运行设备上进行不停车情况下的装接和拆卸。用慢应变速率法使试样受载,该法具有在短期内产生应力腐蚀开裂的优点。装置小巧,采用2.54cm(1时)直径的阀门连接,以压缩气体作为动力源的液压气缸使试样加载。初期试验是在室温空气中对低碳钢试样进行试验。在2.76MPa(400Psi)液压系统压力下,液压加载
A portable slow strain rate stress corrosion test device Portable test device is used to determine the dynamic medium stress corrosion cracking characteristics of the device in the laboratory, the factory and the pressure is less than 13.8MPa (2000Psi), the temperature is below 204 ℃ ( 400 ° F) on-site operation of the equipment without stopping the case of the installation and removal. The specimen is loaded with a slow strain rate method which has the advantage of producing stress corrosion cracking in the short term. Device compact, with 2.54cm (1:00) diameter of the valve connected to the compressed gas as the power source of the hydraulic cylinder to load the sample. The initial test was to test low-carbon steel specimens in air at room temperature. Hydraulic load at 2.76MPa (400Psi) hydraulic system pressure
