Hydrogen uptake in steel structures can cause a degradation mechanical properties such as toughness, and induce cracks. This phenomenon is widely known hydrogen embrittlement. For structural steels subjected to cathodic protection or pipelines transporting high-pressure gas, embrittlement represents an important challenge. Charpy V-notch testing provides fast inexpensive method for quantifying ...

Natural gas could become one of the most important and strategic energy source in the years to come, even if the renewable sources growth will play a fundamental role in the “next green power energy”; however natural gas has the chance to assure a continuous and reliable energy supply on a economically viable, long term base span. Potential routes for gas export from giant mid-continental field...

The oil and gas production has grown steadily, the care with its transportation grid needs to be maintained expanded. pipeline used in transport of by-product requires materials high mechanical strength, toughness, fatigue resistance. chemical composition distribution, amount, morphology final microconstituents steel are paramount importance once it will directly influence properties. fracture ...
