ANSI B16.5 Lap Joint Flanges

ANSI B16.5 Lap Joint Flanges are similar to a Slip On flange. The main difference is at the radius located at the intersection on the face of the lap joint flange and the bore which has the ability to accommodate the flanged portion of the Stub End. While a Lap joint flange is not manufactured with a raised face, they are used in tandem with a stub end. The load or pressure bearing ability of a Lap joint flange is only slightly better than a slip on flange. Whereas in comparison to Welding Neck flanges, the fatigue life of this component is only one tenth that of the former. A  Carbon steel lap joint flange is slipped over a pipe and is seated on the back of the stub end. Both the flange and the stub end are held together by the pressure of the bolts.

Since the use of lap joint flanges includes a separate stub end component, the two-piece Lap joint flange connection works out to be a cost-effective solution. This is noticed especially when the alloys used in their manufacture can be of a lower grade e.g. carbon steel in comparison to the material of the stub end. As the material to make the stub end is required to match the pipe grade, due to its contact with the conveyed fluid, particularly for piping systems that are stainless steel or nickel alloy based.

Using a PN16 Lap Joint Flange can have certain special advantages, such as :

  • Freedom for the flange to swivel around the pipe, which in turn facilitates the alignment of opposing flange bolt holes.
  • Lack of contact between the flange and the fluid in the pipe often permits the manufacturer to use inexpensive carbon steel in conjunction with a corrosion resistant pipe.
  • In piping systems where erosion or corrosion could occur rapidly, the Stainless steel lap joint flange could be salvaged for re-use.
