47 -- FABRICATION OF 36,000 PPH TWO STAGE NONCONDENSING STEAM EJECTOR SET SOL 9-WSRE-W10-6-22Q DUE 032696 POC Contract Specialist: Lindsey D.Irby, (505) 524-5139 Contract Officer: Vernon J.Brown, (505) 524-5134 This notice constitutes a Request for Quotation (RFQ) for (Fabrication of a two stage noncondensing steam ejector set,as specified below: 1. Absolute blank-off pressure at the first stage ejector suction inlet shall be stable and be at or below 5 torr. 2. The ejector set will be designed to use 36,000 lbs/hr saturated steam at 200 psig pressure. The ejector performance curve with both stages operating will be the approximate shape of a curve defined by the blank-off pressure of 5 torr and the following three conditions. There shall be a smooth transition in suction pressure between all load points. a. First stage ejector suction inlet pressure will be 18 torr with 0.22 lb/sec flow of rocket engine exhaust products as defined in para. 3 below flowing into the ejector suction inlet at 200 degrees F. b. First stage ejector suction inlet pressure shall not exceed 20 torr with 0.8 lb/sec flow of rocket engine exhaust products as defined in paragraph 3 below flowing into the ejector suction inlet at 200 degrees F. c. First stage ejector suction inlet pressure will be 180 torr with 2.2 lb/sec flow of rocket engine exhaust products as defined in paragraph 3 below flowing into the ejector suction inlet at 400 degrees F. 3. The composition by mass of entrained gases at the ejector suction inlet consists of approximately 0.73% H2; 41.2% N2; 13.2% CO2; 31.9% H2O and 1.5% CH2. The average molecular weight is 22.612. The temperature of the gas at the Y stage ejector suction inlet is as stated in paragraphs 2 and 3 above. 4. The atmospheric stage ejector shall be designed for a discharge pressure of 14 psia to allow for the future installation of a scrubber. 5. The steam header and nozzles will be designed for a 250 psig steam pressure with ample corrosion allowances. The steam inlet interfaces will be a raised face 300 pound ANSI flanges. 6. The ejectors shall be constructed of carbon steel with the steam nozzles fabricated from 300 series stainless steel. 7. The ejector suction inlet shall be a 24-inch diameter flat face 150 pound ANSI flange located on the end of the ejector. The suction inlet shall be located on the side of the atmospheric ejector stage. Documentation: 1. Two sets of shop drawings with dimensions shall be submitted to the Buyer within two weeks after award of contract. These drawings will include but not be limited to weights, support details and the throat diameters for both stage ejector shells and steam nozzles. 2. Two copies of ejector performance curves, mass flow of Free Dry Air vs. inlet suction pressure will be submitted within four weeks after award on contract. Curves will be furnished for the two stage ejector set including interstage suction pressure and for the atmospheric stage operating alone. -- Delivery of the items to WSTF (FOB ORIGIN) is required ON or before June 17,1996. -- This notice serves as the only solicitation; quotes are being requested and a written solicitation will not be issued -- This procurement is being conducted under the Simplified Acquisition Threshold (SAT) portion of the Federal Acquisition Streamlining Act (FASA) -- ( -- If the end product(s) quoted is other than domestic end product(s) as defined in the clause entitled ''Buy American Act -- Supplies,'' the quoter shall so state and shall list the country of origin -- -- The quoter shall state in their quote their size status for this procurement as well as whether they are minority or woman-owned -- The SIC code and the size standard for this procurement are (SIC code 3443 and 500 employees -- Questions regarding this acquisition must be submitted in writing to the contracting specialist via E-mail at lirby@smtp2.wstf.nasa.gov or by phone at (505) 524-5139 or to the contracting officer via E-mail at vbrown@smtp2.wstf.nasa.gov or by phone at (505) 524-5134. -- Quotation are due 17 days after publication of this notice in the Commerce Business Daily and must be submitted to the address specified above to the attention of the (contracting officer/specialist) -- The quotation must include Representations and Certifications which may be obtained via the Internet from the JSC Procurement Home Page under Procurement Reference Documents -- -- Technical acceptability will be determined by information submitted by the quoter providing a description in sufficient detail to show that the product quoted meets the Government's requirement -- The period of time expected for the Contracting Officer to solicit/evaluate vendor quotes and issue the purchase order will be approximately 18 days from publication of this notice.
