{ "item_title" : "An Introduction to Cathodic Protection", "item_author" : [" J. Paul Guyer "], "item_description" : "Cathodic protection is a method to reduce corrosion by minimizing the difference in potential between anode and cathode. This is achieved by applying a current to the structure to be protected (such as a pipeline) from some outside source. When enough current is applied, the whole structure will be at one potential; thus, anode and cathode sites will not exist. Cathodic protection is commonly used on many types of structures, such as pipelines, underground storage tanks, locks, and ship hulls.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/1/72/007/428/1720074283_b.jpg", "price_data" : { "retail_price" : "49.00", "online_price" : "49.00", "our_price" : "49.00", "club_price" : "49.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
