ERW pipe surface quality is much better than the seamless steel pipe .
In terms of corrosion ERW can last longer than seamless pipe roughly 3-4 years longer. Though the price is expensive for ERW. It really depends on the manufacturer if they provide it for long pipe distance.
But generally...
If there is a 2% of H2O molecular content, there is a possibility of black powder. To prevent it make sure that after hydro-testing and removal of air through the pipe, the drying process is done more than once (its crucial) to secure that water content isn't seen.
