High frequency girth welds on high strength 5L X70 & 80 blamed for failure (tentatively). DOT is on them like white on rice. Attached correction order.

I have seen some reports on at least one recently installed pipeline in the USA that indicated reject rates of radiographed girth welds at over 30%.
