E-MAIL: Stanley W. Ward, S.W.WARD@larc.nasa.gov. NASA Langley Research Center plans to issue a Request for Quote (RFQ) for an in-line filter assembly. The filter shall be an in-line type, and shall fit in the existing housing as shown on specification drawings. The referenced drawings will be supplied with the RFQ when mailed out. The filter assembly shall be designed for air service at 2200 psig design pressure, and shall be suitable for ambient to 1600 degrees F design temperature, and shall be in accordance with the following: A. Filter element(s) shall be as follows: 1. Shall have a flow rate of 30 lb/sec with a clean pressure drop of no more than 20 psid as measured from the inlet flange to the outlet flange. 2. Shall have an Absolute Filtration Rating of 5 microns. 3. Shall have a temperature range of ambient to 1600 degrees F. 4. Shall have a metal filter medium. 5. Shall be ultrasonically cleanable. 6. Shall withstand a differential pressure across the element and tube sheet of at least 100psid. 7. Shall be fabricated so that the element(s) is/are welded to the tube sheet. 8. Shall be such that all filter material joints are fabricated using either the Gas Tungsten Arc Welding (GTAW) or Electron Beam Welding process. 9. Shall be tested using the Bubble-Point Test Method in accordance with the SAE Aerospace Recommended Practice 901 or equivalent procedure. 10. Fillet welds, partial penetration groove welds, and full penetration groove welds shall be inspected by the liquid penetration (PT) method. Porous metal weld joints shall be visually examined at a magnification power of 10x. Both tests shall be performed by the Contractor at his place of performance before delivery for the purpose of detecting all of the weld discontinuities in 11., below. 11. Welds shall be rejected and the filters rejected for any of the following reasons: a) Cracks in the weld or heat affected zone; b) Porosity of welds greater than 5 microns; c) Weld reinforcement or drop through greater than 1/16 inch; d) Sink in or undercutting greater than 0.025 inch deep. 12. Shall have a support structure for multi-element tube sheet. The structure shall provide support for all of the element(s). Support shall be provided at the intermediate and endpoints of the element(s). 13. Shall have lifting lugs for element/tube sheet removal. A. Filter assembly shall be furnished with the following information as deliverables: 2. Calculations to support the flow conditions required by section A., above. 3. Calculations demonstrating that the element(s) will withstand a differential pressure of at least 100 psid. 4. Certified results of all weld inspections and bubble testing. 5. Certified results of filter element(s) cleaning and cleanliness. 6. Certified accurate as-built element/tube sheet assembly drawing. 7. Certification of materials used in fabrication. 8. Certification of the weld process(es) used in fabrication. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). The Government intends to acquire a commercial item using FAR PART 12. This procurement is not a small business set-aside. The SIC Code and Size Standard are 3569 and 500 employees, respectively.
