48--VALVE,BALL

This contract pertains to the procurement of a 6-inch ball valve for use in a critical shipboard system under the TRIPER Program, designated as Level I Special Emphasis material due to its vital role in ensuring ship safety and operational integrity. The valve must comply with stringent technical specifications, including Naval ships system drawings 4558734, DM117384, and ER2640-801X1E1, with exacting requirements governing material composition, manufacturing processes, and inspection protocols. Key components such as the body, stem, studs, and self-locking nuts must be fabricated from certified alloys including ASTM-B369, QQ-N-286, ASTM-B505, and SAE-AMS-6931, with mandatory quantitative chemical and mechanical testing, non-destructive examinations like radiography and dye penetrant inspection, and pressure testing at specified tolerances. All materials must maintain full traceability from raw stock to finished component through permanent markings, heat/lot numbering, and accompanying certifications, with no re-certification allowed for altered properties unless documented and re-identified. The valve must be assembled using approved lubricants, and specific surfaces such as the ball’s spherical finish must meet exacting RHR values through a proprietary polishing procedure, while all threading, welding, and brazing must conform to strict Navy-standard procedures and qualified personnel. The contract mandates a comprehensive quality assurance framework requiring ISO-9001 compliance supplemented by ISO-10012 and ISO/IEC 17025 for calibration, or the alternative MIL-I-45208 and MIL-STD-45662 system. The prime contractor must maintain control over all subcontractors, ensuring that purchase orders include applicable quality requirements and that traceability and certification are preserved through every production stage. Government inspection and acceptance are required at source, with mandatory submission of radiographic film, shooting sketches, and test reports prior to shipment, and a full 100% inspection of all certifications, traceability markings, and non-destructive test results. Delivery is scheduled for 450 days after certification submission, with early or partial deliveries permitted at no additional cost. The valve must be tagged with an official TRIPER serial number provided by the Government, marked with CID T884305729, and packaged with proper identification. The contract prohibits mercury-containing materials, unauthorized modifications, and non-approved substitutes, and requires
