Pitting on new API5L pipes
Pitting on new API5L pipes
(OP)
Dear All, I got a question on one of the major issue we are facing with one of the manufacturer.
We procure a pipeline material and during the visit to the mill we found many pitted areas on the pipe prior to the external coating.
Is there a specific method to accept/reject these pipes, i.e. depth of pits. Any international or SHELL standards can help on this issue.
Also the plates were kept for one year due to some contractual issues. We are not sure whether these pits are because of atmospheric corrosion happened on one year or due to poor manufacturing procedure/quality.
Thanks

You may wish to seek added compensation should pipe(s) fail during hydro test and possibly extend warenty due to the present extent of noncompying material regarding HIC failures.
