To provide a solution to aluminum irrigation pipe corrosion, Cortec developed EcoLine AL-Corr, a biobased corrosion inhibitor solution.
Cortec Corporation has recently developed EcoLine AL-Corr, a biobased corrosion inhibitor solution for the protection of aluminum (AL 3003 and AL 1100) irrigation pipes, which are exposed to a naturally corrosive environment and can carry a high level of chlorides and sulfates. Protecting irrigation pipe internals proves particularly important to ensure a long service life of the equipment, fewer downtime and repair efforts and to facilitate a more efficient watering.
Based on results of ASTM G31 immersion testing, EcoLine AL-Corr is able to reduce corrosion rates by more than 90% in immersion conditions. Testing on two aluminum alloys over the course of five weeks at 104 °F (40 °C) showed the following results: 91.18% protection for AL 3003 metal and 99.03% protection for AL 1100 metal.
