Ultrasonic Phased Array Examination of Butt Fusion Joints of High-Density Polyethylene (HDPE) Pipe
ثبت نشده
چکیده
High-density polyethylene (HDPE) piping has been used in place of steel alloys in the petrochemical, power, and mining industries due to its exceptional resistance to corrosion and erosion. Recently, HDPE has also been used for nuclear safety-related cooling water applications. The application of nuclear quality assurance requirements creates reasonable assurance that the production fusion joint is sound. Ultrasonic time-of-flight-diffraction (TOFD) inspection of fusion joints is an easily employed nondestructive examination tool that can be used to provide some assurance of fusion-joint integrity. As a supplement to this test, ultrasonic phased array (UTPA) inspection of simulated fusion joints has also been evaluated as a non-destructive examination tool in order to provide additional assurance of fusion-joint integrity. This application note outlines the potential for phased array inspection of HDPE pipe joints.
