Corrosion occurring with a pipeline generates free hydrogen. The hydrogen atom is so small that it can actually permeate through the steel pipe and escape. The rate at which the hydrogen escapes reflects the rate of corrosion. Therefore, capturing the hydrogen and measuring its rate of permeation through the steel pipe can help determine when pipes should be replaced. What are the challenges of bonding a stainless steel foil onto a pipe within which the hydrogen can collect and be drawn for measurement? What are the associated hazards and what precautions need to be taken?
“It is unlikely that you will find any specific information on this topic. However, it requires that a thin foil of stainless steel be explosively-welded onto a steel pipe which carries gas. So, you can look into how explosives can be used to weld dissimilar metals, in this case stainless steel to common steel (something that is not easily done with other conventional welding methods). Secondly, you are using explosives in a hazardous environment (pipe carrying gas) and therefore, you need to discuss the precautions that you would take considering the type of blast effects”
