Lap Joint Flanges Pressure Vessel Flange series for frequent dismantling and maintenance
Lap Joint Flanges comprise a stub end butt-welded to the pipe and a loose backing flange that slides over it, these flanges address the need for frequent dismantling and maintenance.
They solve issues related to welding complexities and material compatibility by allowing the backing flange to be made from a more affordable material like carbon steel, while the stub end matches the pipe’s grade.
This design not only facilitates easier assembly and disassembly but also reduces costs without compromising functionality. Ideal for systems where space is constrained and frequent access is necessary,

Lap joint flanges feature a flat face and are always used in conjunction with a stub end.
A lap joint flange slips over the pipe and seats on the back of the stub end and the two are kept together by the pressure of the bolts.
The use of lap joint flanges in combination with stub ends is a cost-effective solution for stainless steel or nickel alloy pipelines, as the material of the lap joint flange can be of a lower grade (generally carbon steel) than the material of the stub end (which has to match the pipe grade, as in contact with the conveyed fluid).
