The steel used to make pipelines can be weakened by hydrogen molecules that are introduced during manufacturing or when the pipeline is transporting oil and gas. USask researchers used the CLS to generate 3D images of the cracks that form inside the steel, to better understand what is happening at a microscopic level. They found that the amount of hydrogen that stays inside the steel and where it accumulates have the largest impact on whether a pipeline will fail. This new information can be used to develop new steels that are more resistant to cracking.
