Preliminary notes Structural life of welded pipes made of API J55 steel by high-frequency (HF) welding has been evaluated. Experimental tests of base metal mechanical properties, including fatigue properties, were conducted on pipes after 70.000 hours of service in an oil drilling rig. The fatigue crack growth rate and fatigue threshold is obtained using… (More)
