Micrographic Investigation of Process Pipelines Metal after Long-Term Operation
It is noted that it will be advisable to assess metal plasticity on morphology of carbide phase identified during non destructive test of micro-structure. The results of pipeline test cuts, as well as microslices made on the pipes surface during repair are given in the Article. In addition to pipeline metal strength and plasticity assessment the non destructive test of microstructure is conducted that increases reliability and safety of operation of the process pipelines made of steel 15Х5М (15Х5М-У).
