RE: API 5L GR B CORROSION INSIDE ACCEPTED.

Nice looking pipes with surface rust blooming - what's wrong with them?

Remember - More details = better answers

RE: API 5L GR B CORROSION INSIDE ACCEPTED.

Unless it's got pitting or imperfections that exceed 12.5% of the wall thickness, it meets the 5L criteria.
