Dear HaiChuan friends, are there any requirements regarding the service life of mechanical equipment and large-scale unit equipment? Are there any specific criteria for making such judgments? And if the usage cycle exceeds 20 years, how do you manage the equipment in that case? ? ? Thank you
I’m not entirely sure. All I know is that the GE 6B gas turbines, which were the first to be introduced in China, have been in operation since the 1980s. It seems they have undergone several major modifications over the years, and their rotors have also been replaced
The condition for retiring a device is that there is an amount spent on maintenance over a certain period of time, expressed as a percentage of the device’s value; if this amount exceeds a certain threshold, the device is retired and replaced, while if it does not exceed that threshold, it can continue to be used. For reference.
Who has specific standards regarding the duration of use, as well as experience in equipment management?
An assessment is needed for this; everything that should be repaired or replaced within a maintenance cycle has already been taken care of, so there shouldn’t be any problems with things like the casing
The depreciation period for general chemical plants is 15 years, but this does not mean that all equipment within such plants has a 15-year depreciation period. The service life of moving equipment and large-scale unit equipment depends on the values obtained from annual equipment inspections and thorough inspections carried out during maintenance. The specific criteria for determining this are the values from these inspections; generally, when the inspection values are at a critical level, enhanced special care is required. A nitrogen fertilizer compressor on display at the Sinopec Nanjing Chemical Company’s factory history museum has an operating life of over 70 years.
70 years? How well this has been processed and maintained!
