Cross-country pipelines are robust enough to transport oil and gas. All these pipes are interconnected, and the welds are meticulously examined using advanced techniques such as ultrasound and X-ray. However, there is an issue: imperfections in the pipe ends (bevel area or pipe body) can obstruct the ultrasound signals, masking defects within the weld. To prevent this, rigorous regulations govern the permissible number of defects on the pipe ends This manuscript examines the requirement for two additional testing techniques, Magnetic Particle (MT) and Penetrant Testing (PT), on the slanted edges (bevels) where the pipes are connected. We will investigate whether these tests are essential even if an ultrasound examination is performed before the creation of the bevels. When an ultrasound examination is used after the bevels are formed, there is an area that is not visible via Ultrasonic Testing. In such instances, MT and PT are essential to guarantee a secure and dependable weld in the field.
