1 P/N VISIT US ON OUR SIZE: '' in ID SIZE: mm ID Updated August 2011 The propellant tank is a spherical pressure vessel constructed from two (2) machined 6AL-4V titanium hemispheres girth welded at the equator. Mounting is accomplished by a base mount welded to the outlet hemisphere. Gas free propellant is provided by an all-metal propellant management device (PMD). A.250 inch O.D by.020 inch wall 304L CRES transition tube is butt welded to the tube extension for the pressurant inlet connection adn to a 3AL-2.5V formed titanium tube for the propellant outlet.
