... Abstract We produce good quality, high strength, and sour resistant steel, but industry confidence in offshore welds to 65 Ksi and conservative codes lead to very thick pipes for all HPHT risers (SCR, Dry tree, drilling) and flowlines.

...) and flowlines (12? × 19.7 + 3mm 316L BuBi® pipe) required the achievement of critical weld acceptance criterion especially in the fatigue sensitive zones for which no weld repairs were permissible. The maximum allowable flaw height as determined by Automatic Ultrsonic Testing (AUT) was 1.5mm. The weld solution...
