Application of Digital Image Processing on Nondestructive Testing of Fusion Joints of Polyethylene Piping by Ultrasonic Technique
In this paper a new combined algorithm is presented considering digital image processing and mathematical morphology techniques for improving the quality of extracted images from NDT evaluations. The demand of polyethylene (PE) pipeline is increased for gas energy transportation and Electrofusion (EF) joining is an essential method to build PE pipeline. Usually, EF joints are considered as weak points for leakage. The main goal is to present a practical method on Non-destructive Testing (NDT) testing of fusion joints in polyethylene piping using ultrasonic image processing technique. The simulations are done using MATLAB platform. Obtained results show that the algorithms developed and applied to ultrasonic signals are highly reliable and precise for quality of NDT testing and monitoring.
