Why & where use Plate Flanges?
- Free of any defects
- Superior grain structure compared to forged or cast products
- Extended service life
- Reduction of the normal maintenance costs
Plate flanges are most widely used in fuel and water pipelines, where two flange plates are bolted together with a gasket in between them. The flange plate will have bolt holes all around the perimeter and will be used to create junctions, tees and joints.

Plate Flange 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.
