Webzone cracking will be controlled by effective low hydro-gen practices, and appropriate preheats. For HAZ hydrogen cracking to occur, it is necessary for the hydrogen to migrate into the heat affected zone, which takes time. For this reason, the D1.1 Code (D1.1-96, para-graph 6.11) requires a delay of 48 hours after completion
WebSteam cracking technology. Steam crackers are large and complex units at the heart of petrochemical complexes, producing the important building blocks ethylene, propylene, butadiene, aromatics and acetylene. They involve cracking hydrocarbon feedstocks in the presence of steam and at temperatures of between 800° and 870°C.

Numerous mechanisms have been proposed to explain the significantly higher fatigue crack growth observed in steels …
Hydrogen embrittlement (HE), also known as hydrogen-assisted cracking or hydrogen-induced cracking (HIC), is a reduction in the ductility of a metal due to absorbed hydrogen. Hydrogen atoms are small and can permeate solid metals. Once absorbed, hydrogen lowers the stress required for cracks in the metal to initiate and propagate, resulting in embrittlement. Hydrogen embrittlement occ…
