Full-Ring specimen was approved to be best representative of tubular good's corrosion. Tubular Dual Wall Corrosion Cell Kit and Full Ring Galvanic Corrosion Kit were innovated and effective galvanic corrosion was detected between walls. The study proposed introducing Jointal Corrosion Stability Index to tubular specifications, pipe joints with low index shall be excluded before marketing or assembling in strings UR - http://172.23.153.220/th.pdf ER -
