Sample for simulating high-temperature and high-pressure flow medium and simulation test method utilizing sample

The invention discloses a sample with a suspending test piece for simulating high temperature/high pressure/flow medium conditions and a corresponding simulation test method. The sample comprises a sample body and connecting heads, wherein the sample body is of a hollow long pipe shape and is connected with the connecting heads, cavities or air holes are formed in the sample body and the connecting heads and are capable of accumulating high-pressure mediums, and therefore, a high-temperature, high-pressure and flow-medium working environment can be simulated; test pieces are further hung in the cavities and are used for measuring and calculating corrosion rate; and the sample body and the connecting heads are tightly connected in a welding manner and can be made of different materials, the sample body can be formed by welding and splicing multiple annular components of different materials, and therefore, corrosion conditions of positions of the wielding heads can be further detected, and multiple groups and m
