Weld neck, slip-on, socket weld, blind, lap joint and fully custom flanges in stainless, duplex, nickel and titanium alloys.
We forge and machine flanges for the pressure classes and face types that export projects actually specify: ASME B16.5 and B16.47 Class 150 to 2500, HG/T 20592-2009 and HG/T 20615-2009 PN series, plus EN 1092-1 and JIS 5K–20K on request.
Every flange can be supplied with a mill test certificate to EN 10204 3.1, PMI verification, hardness and dimensional reports, and third-party inspection at SGS, BV or TUV if your project requires it.
