Hi All,

I need your help with regard to Pitting Corrosion occurring in the body of pipe (new) API 5L-B PSL2:
1. How to decide whether the pitting corrosion is still allowed or not allowed to be used?
2. Any specification the how much area and depth of the pitting corrosion is still allowed?
3. What is a good method for measuring and ensuring the depth of the pitting corrosion?
4. Is there any method for rectifying the pitting corrosion?

Thanks for your help.
Bariyus Salam
