Due to metallurgical improvements in the steel industry, higher strength steels have made significant strides in specified minimum yield strength (SMYS), wall thickness control, toughness, weight per foot, etc. However, one significant factor in these improvements was “no consideration for corrosion allowances”.

Corrosion allowances in steel have decreased with every incremental increase in the improvements of making of higher strength steels. Lower strength metal loss assessments can result in recoat type repairs, while higher strength steels may result in composite/steel sleeve repairs or replacement.

Unfortunately, the US coating industry and pipeline operators have not addressed these changes to offset or compliment the improvements made in higher strength steel. This course addresses this dilemma through direct examination digs and ways to mitigate corrosion.
