Fibroscopy: As opposed to other methods, this practice requires equipment shutdown, and
provides a certain level of knowledge on the internal conditions of machines with limited disassembly needs. Its execution frequency matches the regular maintenance routine of the equipment. Each machine type has strategic access points for this purpose. Notwithstanding routine inspections,specific inspections are carried out on certain parts based on accumulated service hours. The fibroscopy method is not only applied to turbocompressors but also to other items such as inlet filtering cones in natural gas compressors, to determine possible structural damages caused by the entry of foreign matter.
