Circular Machined Flange Disc With Blind Pipe Flange and Raised Inner Face

Raised inner face flatness and bolt hole circle diameter are confirmed using your drawing as reference during first-piece inspection on every blind pipe flange. Welltop's Dongguan CNC milling and turning line produces these under ISO 9001 process controls. Raised face flatness governs whether the gasket seats evenly across the full sealing surface; bolt hole circle diameter determines whether the flange bolts correctly to its mating connection. The production site covers 4,000 m² of production area, serving medical equipment, oil & gas, and shipbuilding applications. Both are documented on the inspection record before shipment. The circular disc body and raised inner face profile are produced from your controlled drawing; bolt hole pitch and face perpendicularity to bore are verified during in-process sampling. Applications include oil and gas pipeline terminations, automotive fluid system closures, and aerospace pneumatic line end caps. Our Dongguan team quotes from your drawing — include to get started.
