Custom Flat Face Plate Flanges Manufactured for Australian Infrastructure Project
Haihao Group has completed manufacturing and final dimensional verification for a dedicated order of flat face plate flanges destined for an industrial client in Australia. Designed for low-pressure water treatment, mining slurry lines, and processing plant infrastructure, these components were fabricated to custom geometric specifications requiring precise bolt circle alignment and flat contact sealing surfaces.
As a reliable flat face plate flange supplier, Haihao Group ensures every flange maintains flat face (FF) contact integrity, preventing mating cast iron equipment or full-face rubber gaskets from cracking during torque application.

Precision Machining & PCD Hole Pattern Accuracy
In piping systems utilizing full-face soft gaskets, hole pattern accuracy dictates field installation efficiency. For this Australian shipment, CNC machining centers drilled the pitch circle diameter (PCD) hole patterns with zero positional deviation, guaranteeing immediate bolt hole alignment during line fit-up.
Working as an experienced flat face plate flange supplier, our machining team maintained strict tolerances across both sizes:
Small-Bore Units (OD 279 mm): Engineered with an ID of 170 mm and an 8-hole ∅22mm pattern along a 235 mm PCD to handle low-profile pipe connections smoothly.
Large-Bore Units (OD 406 mm): Built with an ID of 276 mm, 20 mm thickness, and a 12-hole pattern on a 356 mm PCD, providing maximum torsional rigidity across wider pipe spools.
Strict Quality Inspection & Australian Market Standards
Piping infrastructure across Western Australia and Queensland demands reliable surface finishes to prevent fluid bypass under low-to-medium operating pressures. Choosing a trusted flat face plate flange supplier means receiving certified materials backed by thorough quality assurance.
Every plate flange in this order underwent 100% manual calipers measurement, smooth facing surface checks, and ultrasonic testing to rule out internal plate lamination. Surface preparation included smooth phonographic or flat lathe turning to allow soft gaskets to seat uniformly without excessive bolting force.
