... of ASTM A516, grade 70, low-carbon steel plate. A steel angle had been formed into a ring was continuously welded to the inside wall of the vessel. The groove formed by the junction of the lower tray-support weld and the top part of the weld around the nozzle was found to have a crack. Pits and scale near...

... that the material of the vent header met the mechanical and chemical properties of ASTM A516 Grade 70 carbon-manganese steel material and microstructures were consistent with this material. Fracture faces of the cracked pipe were predominantly brittle in appearance with no evidence of fatigue contribution. The NDTT...

... diameter boiler drum fabricated of 18 cm (7 in.) thick ASTM A515, grade 70 steel plate failed during final hydrotesting at a pressure of approximately 26 MPa (3.8 ksi). The shock wave from the vessel rupture also damaged several connected headers and piping runs. A schematic of the crack path, including...

...) diameter debarking drum was welded in the field, where several 3 m (10 ft) long shell course sections (35 mm, or 1.375 in., thick) of ASTM A36 plates were being girth welded using shielded metal arc welding E7018 electrodes. To expedite the production rate, the contractor switched to flux cored arc welding...
