Synopsis : This paper reports the inspection results of corrosion of port and harbor structures at Chiba Works and maintenance techniques for them. Differences in the corrosion rate of steel material between with and without corrosion protection was investigated. Electrode potential monitoring and visual inspection of aluminum alloy anode were proved to be effective in quality control of cathodic protection. The life of anode is expected to be extended by coating the structure at the tidal zone. For localized holes at steel pipe piles and steel sheet piles, some repairing methods have been developed and carried out. Finally the newly developed KPP (Kawasaki polyethylene or urethane resin coated pipe) pile is introduced as heavy-duty protective treatment. |
