Rev 3

SCOPE of SUPPLY

The scope of this procurement covers fluid transfer lines to connect NASA SMiRF vacuum chamber to routable dewar. The purpose of these fluid transfer lines is to supply and return neon from the test tank to an integrated refrigeration system. The integrated refrigeration unit uses a neon cooling loop to liquify oxygen from ambient temperature. In this application the neon will be regulated to 100psia to be transferred between the refrigeration unit and the test tank. The system Maximum Allowable Working Pressure (MAWP) is 150 psig. All process fluid piping shall be designed, fabricated, examined, inspected, and tested in accordance with the latest revision of ASME B31.3 Process Piping Code for normal fluid service for a MAWP of 150 psig.

The flex hose shall be tested to 1.5 times the MAWP in accordance with ASME B31.3 Normal

Fluid Service, the test pressure shall be 225 psig. The flex hose shall have a burst pressure of at least four times the MAWP of 150 psig. The flex hose assemblies shall be tagged with a permanent stamped metal tag or marked along the length of the hose. The tag or marking shall show the date of the pressure test, the MAWP, design temperatures, the manufacture part number and the fluid it will accommodate.
