The Fatigue Life of Gas Pipe Lines

The trans mountain pipe line that was washed out by the atmospheric river flooding has been exposed to a lot of up and downs. When something gets bent again and again and again, even small amounts, the material can adually changes its structure. And if there's hydrogen present, hydrogen can sneak in and fill dislocations that are produced by this pyc. It's kind of like a, i'm trying to find an analogy, coming up short. But if you have two crystals and they're in contact with one another, they can share forces that help to blue them together. If the space between them is full of hydrogen, there's a sheer plane, and then, and so again
