A flange description needs six inputs
At minimum state nominal size, pressure class, type, facing, material grade and dimensional standard. Weld-neck flanges also need bore or matching pipe schedule; ring-joint flanges need the groove details.
Material and dimension standards
ASTM A182/A182M governs forged material, while ASME B16.5 or B16.47 governs dimensions and ratings. Both belong on the purchase order together with project supplementary requirements.
Inspection
Ordered controls can include heat treatment and mechanical records, PMI, dimensional report, ultrasonic or liquid-penetrant testing, hardness and third-party witness points.
