COUPLING,VALVE STEM

Quick Summary

The Department of the Navy, NAVSUP Weapon Systems Support Mechanicsburg, is soliciting for COUPLING,VALVE STEM components. This is a Total Small Business Set-Aside opportunity. These components are designated as Special Emphasis Material (Level I, Scope of Certification, or Quality Assured) due to their critical use in shipboard systems, where failure could lead to severe consequences. Responses are due by May 4, 2026.

Scope of Work

This solicitation requires the provision of Coupling Sets, consisting of Pieces 8, 9, 93, and 181, manufactured in accordance with Naval Sea Systems Command Drawings 803-4384539, 803-4384678, and DRN 4384678C01, with specific amplifications and modifications detailed in the solicitation. The material is crucial for shipboard systems, necessitating stringent quality controls.

Technical Requirements

The opportunity outlines detailed material specifications and testing requirements:

• Material: Specific alloys and tempers (e.g., Forged ASTM-B283, Alloy C63200, Temper TQ50; QQ-N-281, Class B; MIL-DTL-1222, Type II) for various coupling pieces, with defined mechanical properties (Tensile Strength, Yield Strength, Elongation).
• Testing & Certification: Extensive Non-Destructive Tests (Liquid Penetrant, Dye Penetrant, Ultrasonic Inspection), Quality Conformance Tests, and Slow Strain Rate Tensile Tests are mandated. Certifications are required for specific items and tests, with a list of approved laboratories for certain tests.
• Fasteners: Detailed requirements for K-MONEL fasteners, including heat treatment, thread forming, wedge tensile tests, and thread inspection per FED-STD-H28 series. Thread lubricants containing molybdenum disulfide are prohibited; Anti-galling compound A-A-59004 must be used. Internal threads must be cut, not cold-formed.
• Welding/Brazing: Procedures and personnel must be qualified under S9074-AR-GIB-010A/278, 0900-LP-001-7000, or S9074-AQ-GIB-010/248. Repair welding is not permitted on QQ-N-286 material.

Quality Assurance & Traceability

• Quality System: Contractors must maintain a quality system compliant with ISO-9001 (with ISO-10012/ANSI-Z540.3/ISO-17025 calibration) or MIL-I-45208 (with MIL-STD-45662 calibration).
• Government Quality Assurance (GQA): Performance is subject to GQA at source by a DCMA QAR.
• Traceability: Critical for Level I/SUBSAFE systems, requiring unique traceability numbers (heat-lot, heat-treat) marked on materials per MIL-STD-792. Material certification test reports must accurately reflect compliance.
• Inspection: Comprehensive receiving, in-process, and final inspection requirements, including 100% inspection for traceability marking and certification data.
• Packaging: Must comply with MIL-STD 2073.
