Types of Flanges
- Threaded Flange
- Weld Neck Flange
- Slip On Flange
- Socket Weld Flange
- Blind Flange
- Lap Joint Flange
- Plate Flange
- Forged Flange
Lap Joint Flanges have all the same common dimensions as any other flange named on this page however it does not have a raised face, they used in conjunction with a “Lap Joint Stub End”.
These flanges are nearly identical to a Slip On flange with the exception of a radius at the intersection of the flange face and the bore to accommodate the flanged portion of the Stub End.
Their pressure-holding ability is little, if any, better than that of Slip On flanges and the fatigue life for the assembly is only one tenth that of Welding Neck flanges.
They may be used at all pressures and are available in a full size range. These flanges slip over the pipe, and are not welded or otherwise fastened to it. Bolting pressure is transmitted to the gasket by the pressure of the flange against the back of the pipe lap (Stub End).
Lap Joint flanges have certain special advantages:
- Freedom to swivel around the pipe facilitates the lining up of opposing flange bolt holes.
- Lack of contact with the fluid in the pipe often permits the use of inexpensive carbon steel flanges with corrosion resistant pipe.
- In systems which erode or corrode quickly, the flanges may be salvaged for re-use.

Lap Joint 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.
