![]() The layer of CRA creates mode conversions which make data analysis extremely difficult. However, when a CRA is bonded to the inside of the pipe, the alloy often has properties, such as grain structure and velocity, that differ from the pipe’s parent material. When inspecting a weld with phased array pulse-echo or pitch-catch standard configurations, the ultrasonic beam rebounds at the bottom of the part so that the beam’s second leg passes through the weld bevel and cap area. The weld that joins pipe segments together is also made of the CRA material. In many cases, the parent material of the pipe is carbon steel with a layer of CRA bonded to the inside. Various combinations of CRA materials and thicknesses are used. In today’s pipeline industry, corrosion resistant alloys (CRAs) are widely used to help protect pipelines that transport corrosive fluids.
