Protecting an existing ductile iron water main using linear anodes
Publication details: ene. 2008Description: 5 p. ; 38-42Subject(s): In: Materials Performance 47Summary: A Wisconsin water utility has implemented a demonstration project using horizontal diretional drilling equipment to install a continuous linear anode directly alongside an existing water main that has experienced significant external pitting corrosion. The results of the initial demonstration project suggest that a 40-year life extension of the water main may be achievable at a cos that is significantly less than the replacement costo of the pipe.| Current library | Status | Barcode | |
