Characterization of Corrosion Behavior of Low Carbon Steel Oil Pipelines by Crude Oil

الوصف الكامل (Full Abstract)

Corrosion and erosion–corrosion in weld joints of petroleum pipelines were investigated by the studying the corrosion of
carbon steel in crude oil and water extraction from oil. The experimental work tests of erosion- corrosion were done using
special device which was designed according to (G 73) ASTM. The work tests were achieved using traditional weight loss
technique to measure weight loss rates in (mpy) Unit, the tests above were done in pumped media and pumped media had
constant pressure of 1 bar, flow rate Q = 36 L/min, temperature 25 ?C and pH = 6.56 for erosive-corrosive media. Weight
loss method was used in which test specimens of carbon steel, with a known weights, were immersed in the oil for a total
exposure time of 60 days and for 10 days in water. Metallographic observations and micro-hardness measurements were
also performed on specimens taken from the parent metal, heat affected zone and weld metal. The obtained results clearly
indicate a degradation of the mechanical properties of steel welds.
