Structural integrity assurance of casing pipes in the oil

2 Material properties and experimental testing of the pipe with a pre-crack . Material properties are determined on specimens taken from the casing pipe manufactured by HF welding (producer US Steel, Serbia). The pipe was in exploitation in an oil drilling rig, and is withdrawn during a reparation procedure after about 70000 hours (8 years). What is Oil Casing? - Seamless Steel PipeOil casing is a steel pipe used to support the walls of oil and gas wells to ensure the normal operation of the entire oil well after drilling and completion. Each well uses several layers of casing according to different drilling depths and geological conditions.
