SOURCES SOUGHT NOTICE
Additively Manufactured Gate Valve Components
THIS IS A SOURCES SOUGHT NOTICE ONLY. This notice does not constitute a request for quotations (RFQ) or invitations for bid (IFB), nor does it restrict the Government’s acquisition approach. No contract will be awarded from this announcement. The Government is not obligated to reimburse respondents for any information submitted in response to this notice.
1. Purpose
Naval Supply Systems Command (NAVSUP) – Weapon Systems Support (WSS) is conducting market research to identify potential sources with the capability to design, produce, and deliver the following end items using additive manufacturing (AM) methods for specific piece part components.
Nomenclature NIIN QTY Part Number Drawing
Valve, Gate 013965550 2 GVB‐2‐M23854 DWG 2866‐M23854, Gate Valve Assembly.
Project Particular Document (PPD)s associated:
PPD 802‐8979758 ‐ AUSTENITIC CHROMIUM‐NICKEL STAINLESS STEEL, CORROSION‐RESISTANT,LASER POWDER BED FUSION, ADDITIVELY MANUFACTURED ‐ This specification covers material made from additively manufactured (AM) austenitic chromium‐nickel stainless steel alloy using the laser powder bed fusion (LPBF) process.
PPD 802‐899910 ‐ REQUIREMENTS FOR USING EXISTING NAVSEA S9074‐AQ‐GIB‐010/248 WELDING PROCEDURES FOR INSTALLATION WELDING OF PARTS PRODUCED VIA METAL ADDITIVE MANUFACTURING ‐ This document contains requirements for assessing the presumed S‐Groups of additive manufacturing (AM) base materials. The S‐Group verification testing required by this document has been selected to demonstrate that the heat‐affected zone of the AM material does not exhibit deleterious behavior when test assemblies or prototypical mock‐ups are welded under limited restraint. This behavior is extended to assert that existing welding procedures and personnel are acceptable for welding of AM parts.
The Government is seeking information from qualified businesses on their ability to meet manufacturing, material, performance, and quality assurance requirements applicable to this part. The Government is also seeking anticipated cost and delivery to produce the described parts/
2. Background
The Government requires companies to produce the end items capable of meeting operational and structural requirements traditionally achieved with conventional manufacturing. In support of modernization and sustainment efforts, the Government is assessing the feasibility and availability of additive manufacturing processes (e.g., powder bed fusion, directed energy deposition,) to produce these parts with equivalent or improved performance characteristics that are outlined within their associated drawings
3. Scope of Work
Interested sources shall demonstrate the ability to:
‐ Utilize additive manufacturing processes to produce full production units utilizing AM for the identified components outlined within the technical data packages and associated PPD’s
‐ Meet dimensional, mechanical, and metallurgical requirements consistent with legacy design specifications or Government provided drawings.
‐ Conduct and document appropriate inspections and testing as prescribed in the associated Technical Data Package(s).
‐ Provide quality control in accordance with the standards outline within the draft Technical Data Package(s)
4. Requested Information
Responses should include the following:
1. Company name, CAGE code, DUNS/UEI, business size classification (large, small, 8(a), HUBZone, SDVOSB, WOSB, etc.).
2. Description of capabilities in additive manufacturing, specifically for metallic components subjected to pressure and fluid control.
3. Experience producing valve components or pressure‐containing hardware for Government or commercial applications.
4. Information on relevant certifications, facilities, and equipment (e.g., type of AM machines, postprocessing capabilities, heat treatment, NDT methods).
5. Examples of past performance related to similar AM parts, including contract numbers if applicable.
6. Estimated lead times and cost for prototype and production quantities.
5. Submission Instructions
Interested firms shall submit capability statements not to exceed 2 pages (PDF format preferred) via email to jeffrey.a.dietrich5.civ@us.navy.mil no later than [Two weeks from posting].
Subject line: “Sources Sought Response – Additive Manufactured WSS Component 013965550 ”
