Strength Properties and Corrosion Resistance of Pump–Compressor Pipes Made of 15Kh5MFBCh Steel after Heat and Thermomechanical Treatment under Various Conditions

详细

The strength, the hardness, the impact toughness, and the corrosion resistance in oil-field media of pump–compressor pipes made of 15Kh5MFBCh steel are studied. The pipes were fabricated using standard and experimental technologies, which differ in the conditions of thermomechanical treatment and final heat treatment. A combination of high strength and corrosion properties of oil pipes is shown to be achieved upon annealing of a bainitic structure.
