SORF Flanges Marking

Every Standards have clearly requirements for steel flanges’ marking style, usually the marking words include seller’s Logo, buyer’s Logo (OEM), standard number, flange’s type, flange’s pressure, flange’s size, flange’s material, place of origin, heat number and other words for convenient to trace. 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 standard, it also must mark on flanges where it is different with normal ones. Another important place is heat number marking, it is the tracing base for every piece flange, and from the heat number we can trace to the beginning of raw material import.
