本发明涉及一种适用于高温高压水环境或汽环境的双釜试验装置及方法，双釜试验装置包括一个大型高压反应釜，以及设置在大釜釜腔内的至少一个小型高压反应釜，小型高压反应釜包括小釜釜体和小釜釜盖，小釜釜盖盖在小釜釜体上，小釜釜体内部具有小釜釜腔，在小釜釜腔内设置有用于挂置金属试片的试片支架。采用上述双釜的试验装置开展高温高压水环境挂片试验，可以同时进行数组相同温度下不同溶液（如溶液浓度不同）对金属试片腐蚀情况影响的对比试验，省时省力；同时可通过更耐腐蚀的小型高压反应釜开展某些强腐蚀性溶液中原有普通不锈钢材质的大容积高温高压反应釜无法进行的试验。 The invention relates to a double-kettle test device and method suitable for a high-temperature high-pressure water environment or a steam environment. The double-kettle test device comprises a largehigh-pressure reaction kettle and at least one small high-pressure reaction kettle arranged in a kettle cavity of the large kettle, the small high-pressure reaction kettle comprises a small kettle body and a small kettle cover, the small kettle cover covers the small kettle body, a small kettle cavity is formed in the small kettle body, and a test piece bracket for hanging a metal test piece is arranged in the small kettle cavity. When the double-kettle test device is used for carrying out a high-temperature high-pressure water environment coupon te
