Attachment 1_852601-1010_B-HULL-PRESSURE_TANK_DISTRO_A.pdf

This document is a technical drawing specification for a Pressure Tank component. The drawing provides detailed engineering specifications and manufacturing requirements for a cylindrical pressure tank assembly with integrated internal components.

The specifications include material composition per NASA HR-1, post-processing requirements including laser powder directed energy deposition and heat treatment cycles, and surface finishing standards. Key manufacturing processes specified are stress relief operations in vacuum or inert atmosphere, hot isostatic pressing at controlled temperatures and pressures, and one-step aging processes with vacuum or inert gas cooling. Dimensional tolerances conform to ASME Y14.5M-2009 standards. The design features include 5/16-18 UNC threads with tap drills, 16 mounting holes evenly spaced around the perimeter, surface roughness machining requirements of 125 microinches except where noted, and dimensional specifications with X and Y axis angles remaining as printed. The tank assembly measures approximately 12.470 inches in width with detailed cross-sectional views showing internal cavity configurations, wall thicknesses ranging from 0.75 to 2.0 inches, and radii specifications throughout. Multiple detailed views (B, C, and D) at various scales provide magnified specifications for critical junction points and thread configurations. The document is marked "FOR OFFICIAL USE ONLY" and carries a distribution statement indicating approval for public release with unlimited distribution.
