It is very important to note that the reactor temperatures (both inside and on the surface) and pressure must always be in accordance with the temperature/pressure charts provided by the reactor supplier. The minimum pressurization temperature (MPT) of the reactor must be strictly respected. This temperature is related to the ductile-to-brittle transition temperature of the reactor material. It should be noted that low-alloy steel reactors are prone to temper embrittlement; as a result, the MPT depends not only on the metallurgical properties of the vessel but also increases as the vessel ages. Hydrogen dissolved in the reactor wall is another factor that can cause embrittlement, and this is also taken into account in determining the MPT. If the MPT is higher than 130°C, the reaction section must be pressurized at the lowest allowable pressure at that temperature (typically one-quarter of the normal operating pressure). What does this mean?
It is very important to note that the reactor temperatures (inside and on the surface) and pressure must always be in accordance with the temperature/pressure charts provided by the reactor supplier. It is important to note that the reactor temperature (both inside and on the outer walls) and pressure must always be maintained in accordance with the temperature/pressure curves provided by the supplier. The minimum pressurization temperature (MPT) of the reactor must be carefully observed. The reactor’s lowest pressure onset temperature (MPT) needs to be closely monitored. MPT is related to the ductile-to-brittle transition temperature of the reactor material. It is associated with the ductile-to-brittle transition temperature of the material used in the reactor. The latter part is a bit too technical. . .
The minimum pressurization temperature (MPT) of the reactor must be carefully respected. It is essential to strictly adhere to the reactor’s minimum starting pressure temperature (MPT) as specified by the supplier. Here, “respected” does not mean “monitored” or “inspected”; rather, it means that it must be obeyed.
It is important to note that the temperature of the reactor (both the internal and surface temperatures) as well as the pressure must correspond to the tables provided by the supplier. The minimum pressurization temperature, MPT, must be respected; this value is related to the material of the reactor and serves as a guide for determining the temperature at which brittle failure may occur. It should be noted that low-alloy steel requires specific temperature treatment. Consequently, MPT is not only dependent on the material of the container but also on its age. The dissolution of hydrogen in the reactor walls is another factor that can contribute to the container’s brittleness. If the MPT is higher than 130°C, the reactor should be pressurized at the maximum allowable pressure (typically 1/4 of the normal operating pressure). A friend translated this text, and I feel there are issues, especially with the last two sentences. Could anyone expertly analyze them?
It is highly recommended to translate it by yourself first before discussing! :)
It has been translated upstairs; I think it’s not very accurate, please correct it
