P2. ATTACHMENT II SKETCH.pdf

This technical drawing is a detailed engineering sketch for a Reducing Weld Neck Flange, Pattern No. 160372, designed for mechanical specifications with precise dimensional tolerances. The technical drawing specifies a 3 x 6 IPS (Inches Pipe Size) component with a maximum working pressure of 700 PSI, manufactured from CUNI material per MIL-C-20155, Type I specification. The drawing includes comprehensive geometric details such as hole spacing, diameter measurements, radii, angles, and specific machining tolerances for different dimensional ranges, with precision tolerances ranging from ±.010" to ±.005" depending on dimension size. The drawing also includes detailed notes about marking requirements for plain and grooved flanges, with specific procurement document suffix conventions (P for plain, G for grooved).
