Abstract: Methods, systems, and computer program products for performing structural screening. Methods include applying pre-defined filter criteria to measurements resulting from an inspected structure operable for eliminating measurement data falling below a designated threshold. Methods further include identifying a baseline defect size associated with the inspected structure. The baseline defect size indicates a largest defect capable of being undetected during inspection. Methods also include identifying tolerance levels relating to the inspected structures factoring in the baseline defect size and attributes of the inspected structure, comparing results of the applying pre-defined filter criteria with tolerance levels identified, and determining a risk of cracking for the inspected structure based upon the comparing.

Abstract: A cylinder for transporting hazardous material such as hypergole material which is fabricated from stainless steel and includes a containment system for containing any spillage in the event of malfunction during loading and unloading. The cylinder also includes a bottom skirt, attached to the lower head of the pressure vessel, and which contains a pocket assembly for the reception of fork lift and pallet lift equipment. A locking system is provided for the valves which will prevent accidental opening or closing of the valve.

Abstract: A method for relieving stress in the microstructure welds and the heat affected zone in the adjacent base metal in low alloy steel by induction heating in a second post-weld heat treatment. The heated area is monitored with a radiation pyrometer to ensure precise temperature control of the procedure.
