Abstract
The degradation of metal structures in pipelines can caused accidents. Some studies and research,
indicate in the field oil and gas industry, that the effects of acidic chemical cleaning solution to an
important role in the process of internal corrosion. In this context we performed an inspection of a
corroded gas pipe by metallographic analyzes. Then we studied the mechanical behavior of the pipe in
the presence and absence of green corrosion inhibitors (Ruta Chalepensis '' FIDJILE '') and synthetic.
Two pipe grades were studies API X52 and API X65 mechanical tests were performed by Charpy test,
Drop weight test, three point bending test and tensile test.
