- Quantitiy:
7 in.( OD: 7″ / ID: 6.276″ ) x 26 ppf x 28 to 34 ft. / Total quantity: 24,000 Meters
7 in.( OD: 7″ / ID: 6.366″ ) x 23 ppf x 32 to 38 ft. / Total quantity 63,000 Meters
Pitting Index
The minimum pitting index required is 36. This index is calculated by the following formula : % CR + ( % Mo x 3.3 ) + ( % N x 16 )
This index is requird not only for well corrosion aspects but also to combat strong atmospheric corrosion during storage in the Persian Gulf Area.
