This Statement of Work outlines the requirements for three custom-made 1.25-inch High Pressure Pneumatic Rotary Unions, designed for use with air and hydraulic fluids. Each unit must feature a 4.4-inch internal bore, be interchangeable, and comply with ASME Boiler and Pressure Vessel Code standards. The rotary unions should be defect-free for one year post-delivery and built from corrosion-resistant materials that meet specified pressure and weight limits. Key specifications include an average flow rate of 10 lbm/sec, a maximum flow rate of 30 lbm/sec under operating pressures up to 1500 psi, and precise dimensional tolerances for inner and outer diameters, ensuring three independent flow paths for high-pressure air and hydraulic lines. During the checkout process, the units must undergo hydro testing at 2250 psi and leak testing with strict leak rate criteria to ensure reliability and safety in operation. This document serves as a detailed guide for potential vendors responding to the government’s request for proposals related to specialized rotary union manufacturing.

The memorandum from the Air Force Test Center at Arnold Air Force Base outlines the intent to sole source a contract to Dynamic Sealing Technologies Inc. for High Pressure Pneumatic Rotary Unions. Market research concluded that Dynamic Sealing is the only vendor meeting the specifications required for this purchase. The acquisition will follow FAR Part 13, Simplified Acquisition Procedures, with a firm-fixed price purchase order anticipated to be awarded by September 26, 2024. While the notice indicates that this is not a request for competitive proposals, responsible vendors who can meet the outlined requirements may submit a business concept by September 9, 2024. Interested parties should direct their submissions to the designated contracting officials via email. This document underscores the government's approach to procurement under specific regulations while allowing for potential vendor submissions in specialized areas.

The document details a single-source justification for procuring three custom high pressure pneumatic rotary unions needed for testing at Arnold Air Force Base (AFB). Dynamic Sealing Technologies, Inc. (DSTI) is identified as the only vendor capable of delivering the items by the critical deadline of March 1, 2025. The justification stems from previous work conducted by DSTI under a $10K subcontract, which included significant engineering resources from Arnold AFB estimated at $9K. Competing the contract would lead to $35K in duplication costs and extensive delays, pushing delivery into July 2025 and incurring an additional $3.2 million in test-related expenses. Market research was conducted to explore competition while ensuring compliance with federal acquisition regulations. The contracting officer determined that, given the urgency and specialized nature of the required equipment, justifying single-source procurement is warranted, and future requirements will be evaluated as they arise. This document highlights the mechanisms within federal contracting aimed at ensuring efficiency and cost-effectiveness in urgent procurement situations.
