Circular Raised-Face Flange Component with Pipe Flange and Four Equally Spaced Bolt Holes

A pipe flange with raised face sealing surface machined outside tolerance risks leakage under pressure cycling that no gasket can fully compensate. SYGO machines carbon steel pipe flanges in Pinghu with raised-face flatness and bolt-hole pattern controlled to your specification callouts through CNC turning; flange face runout is checked before release to confirm sealing integrity. Bolt-hole position and pitch circle diameter are measured in-process; dimensional records are primarytained under IATF 16949 and ISO 9001 certification; the same quality system applied to hydraulic, pump, and pressure vessel flanges served by our Zhejiang facility. 70 staff operate from our plant (in excess of 4,000 m²) with turning, milling, and surface grinding capabilities, with clients across automotive, aerospace, and medical equipment sectors. When submitting, include your drawing with pipe standard, flange face spec, and bolt-hole pattern for a direct quotation.
