.... Consistent with obtaining results that are of practical use, in the work reported here only field exposure tests were employed using coupons cut from a commercial pipe. FIELD EXPOSURES AND PIT DEPTH MEASUREMENT The coupons 100mm x 50mm in size were cut from an industry- standard API Spec 5L X56 longitudinal...

... (1018) coupons that were approximately 255 mm long, 75 mm wide, and 1 mm thick were used as the metal substrates in this investigation. Similar aluminum and steel coupons that were 50 mm long, 15 mm wide, and 1 mm thick were also used. They were purchased separately and coated independently using...
