Such properties as strength and plasticity of extension, resilience viscosity and hardness were selected from stress-strain properties. The results were analyzed and were made such conclusions: - the exploitation of pipeline has a negative influence on its stress-strain properties; - steel hardness of pipeline decreases after its exploitation; - the exploitation of pipeline decreases the viscosity of steel.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
