... Abstract An investigation was conducted to determine why 16 out of 139 pipe bends cracked during hot induction bending. The pipe conformed to API 5L X65 PSL2 line pipe standards and measured 1016 mm (40 in.) in diam with a wall thickness of 18.5 mm. A metallurgical cross section was removed...

... Abstract The genesis of failure of 6.1 mm thick electric resistance welded API 5L X-46 pipes during pretesting at a pressure equivalent to 90% of specified minimum yield strength was investigated. Cracks were found to initiate on the outer surface of the pipes in the fusion zone and propagate...

... Abstract A section of pipe in a hydrocarbon pipeline was found to be leaking. The pipeline was installed several decades earlier and was protected by an external coating of extruded polyethylene and a cathodic protection system. The failed pipe section was made from API 5L X46 line pipe steel...

... (API) grade A (207 MPa, or 30 ksi) to API 5L-X70 (483 MPa, or 70 ksi). Generally, API 5L Specification steels with yield strengths above 359 MPa (52 ksi) are microalloyed and controlled rolled to achieve the desired strength and fracture properties. Pipeline wall thicknesses are based on the pressure...

... for ASTM A36, API 5L, X52, and X70 steel. A significant increase in crack-growth rate, observed across a wide range of stress-intensity-factor amplitudes, was attributed to hydrogen uptake into the steel. Metastable sulfur oxyanions (e.g., thiosulfate and tetrathionate) can promote severe...
