47 -- DESIGN, FABRICATE AND INSTALL PROCESS PIPING SYSTEM FOR A4 TEST CELL COOLING SOL F40650-97-R-0025 DUE 071797 POC Lynn Jefferies, Contracting Officer (615-454-7841) This procurement is for the design, fabrication and installation of a process piping system to transport process air from an existing piping system to three existing test cells at the Engine Test Facility, Arnold Engineering Development Center, Arnold AFB, Tennessee. The new system shall consist of the following elements: a header, approximately 200 feet long, connected to an existing 24-inch tee and containing an isolation valve; three connector legs, each approximately 25 feet long, from the header to existing lines at the test cells and containing an isolation valve in each connector leg; and one new isolation valve in each of the three existing test cell lines. The three existing lines at the test cells are 12 and 14 inches in diameter. Electrical power cables, from existing facility interfaces, and locally operated controls are to be provided for the seven isolation valves. Additionally, an existing throttle valve in one of the test cell lines is to be relocated. The new system shall nominally transport up to 50 lbm per sec air at a pressure of approximately 40 psia and temperatures up to 150 degF. Structurally, the new system must be designed for pressures between 2 psia and 75 psia and for temperatures between -- -100 degF and 150 degF. Performance period is negotiable. Any responsible firm may submit a proposal which will be considered. Foreign participation is authorized.
