Tankers, storage tanks, pipes and pumping equipment are normally constructed using carbon steel, stainless steel or aluminium. It is known that biodiesel and biodiesel blends form sediments when in contact with metals. Natural or nitrile rubber compounds, polyethylene, polypropylene, and polyvinyl materials are also vulnerable to biodiesel. A review of literature on biofuels reveals that least work has been carried out on the corrosion of metals in biodiesel. This paper presents corrosion rates of aluminum, copper, brass and carbon steel in biodiesel obtained from Pongamia Pinnata.
