Was suggested the method of undestructive control for oil and gas pipelines that will increase the productivity of control process and trustworthiness of results. Was suggested the mathematical model for processing of ultrasonic signal of plated waves. It allows separating of individual periods of vibration for determining of necessary parameters of plated waves such as group and phase velocity, extinction and others.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
