The Marking Works for Steel Flanges |
| Every Standards have clearly requirements for steel flanges' marking style, usually the marking words include seller's Logo, buyer's Logo (OEM), standard name, flange's type, flange's pressure (rating), flange's size, flange's material, place of origin, heat number and other words. If the flanges repaired by welding, it must mark on flanges showing this flange repared by welding. If the flange's dimensions (OD, ID, PCD, Thickness, Holes number, Holes diameter, Tolerance etc) are different with the normal size, it also must mark on flanges where it is different with normal size. Another important place is heat number, it is the tracing base for each piece flange. From the heat number we can tracing problem flanges from the flanges material and next process. | |

The Marking Style for European Standards Flanges, DIN, UNI, EN 1092-1 norms etc |
| e.g. LOGO, EN 1092-1, TYPE 01, PN16, DN80, 88.9, P265GH, HEAT NUMBER, MADE IN CHINA or LOGO EN1092-1/01B1/DN50/PN16-40/P245GH/HEAT NUMBER | |
|
The Marking Style for ANSI, ASME Standards Flanges, ANSI, ASME, AWWA norms etc |
| e.g. LOGO, ASME B16.5, CLASS 150#, SIZE, SLIP-ON RF, A105, HEAT NUMBER or 24" ANSI B16.5 150LBS SORF ASTM A105 HEAT NUMBER | |

The Marking Style for BS 4504 norms etc |
| e.g. LOGO, BS 4504, WELD NECK, PN40, DN80, RSt37.2, HEAT NUMBER, MADE IN CHINA | |
|
The Marking Style for GOST 12820, GOST 12821 norms etc |
| e.g. LOGO, GOST 12820, PN1.6MPA, DN80, Q235B, HEAT NUMBER, MADE IN CHINA or 20 - 10 - Ct.20 HEAT NUMBER | |

| e.g. LOGO, SABS 1123, CLASS 4000/3, NB80, A105, HEAT NUMBER, MADE IN CHINA or SANS 1123 T1000/3 100NB A105 HEAT NUMBER | |
| • | We also can marking any words and simple logo on flanges according to buyer's request. The normal marking method is using steel stamp marking machine, on this way it will leave indentation of words and logo on flanges with depth of 1mm or more. The other marking method are using laser marking and electro-chemical corrosion marking machine, we both have the 3 marking method machine for using. |
