Abstract
Pipelines are commonly used in various industries such as oil and gas, water supplies and petrochemical. Composite Pipes are appropriate choice due to some properties including high strength, lightness and high corrosion resistance. It is necessary to employ Non-Destructive Tests (NDT) during construction as well as maintenance of such pipelines, in order to reduce costs. One of the damages that may occur on composite pipes is joint failure which normally happens during construction and operation of the pipes. Furthermore, the most common method of joints in composite pipes is adhesive joint. Ultrasonic Guided Wave (UGW) is suitable method of NDT. In this research, a numerical simulation of L(0,1) guided mode is carried out in order to inspect the adhesive joint between two composite pipes. A parametric study is performed on damage length variation in order to extract suitable feature from damaged pipe signals for damaged joint identification. Using two sensors which are located before and after the adhesive joint, with the purpose of receiving the reflected and transmitted ultrasound wave from the joint, two signals energy indices have been developed for damaged joint identification
