CNC Tapped Threaded Hole Plate Flange, Custom Inner Thread Flat Flange, Unilateral Assembly Plate Flange

   Custom CNC Tapped Threaded Hole Plate Flange is modified customized flat welding flange canceling through bolt holes, adopting full CNC precision tapping process to make standard inner thread holes on flange disc, changing traditional bolt penetration assembly mode, designed for narrow space unilateral fixed equipment pipeline installation scene. Workers only need to screw bolts from single side to finish locking connection, no need double-side bolt penetrating operation, greatly improving construction efficiency of confined space piping.

   We support full customization of thread specification, thread depth, hole quantity, flange thickness and material. Optional material: Q235B carbon steel, 304/316L stainless steel, customizable metric thread, imperial thread special specification. The thread tooth type is full CNC milling, smooth tooth surface, uniform tooth pitch, matched with high-strength custom bolts, anti-slip thread design avoiding bolt loosening under pipeline vibration. Standard PN10-PN25 pressure grade optional, RF sealing face universal gasket matching.

   All thread holes undergo tapping flaw detection to ensure no broken tooth, burr defect. The flange body adopts forging integrated molding, high structural strength, thread hole not easy to slip tooth under long-term locking force. Widely used for tank wall fixed pipe port, mechanical equipment end interface, ceiling narrow space piping, closed container connecting pipe. Support small batch sample customization, short prototype lead time. Provide customized thread inspection report, 12-month thread anti-loosening quality warranty.

Core Spec: Standard: Custom OEM Standard; Pressure: PN10/PN16/PN25; Thread: Metric/Imperial Custom Thread; Material: Carbon Steel / Stainless Steel; Process: Forged + CNC Tapping
