What is difference between slip-on and lap joint flange?
Lap joint flanges are extremely similar to slip-on flanges, with the primary difference being that the bore and face have a curved radius to accommodate a lap joint stub-end. Lap joint flanges and stub-end assemblies are commonly employed in circumstances where regular disassembly for inspection is necessary.
What is the advantage of lap joint flanges?
The pressure-holding capacity of lap joint flanges is little. But it is better than that of slip-on flanges. The Lap Joint works as a backing ring on the stub. The main advantage of lap joint flange is that the bolt holes can be aligned with the matching flange after the welds have been completed.
What is a lap joint used for?

What does a raised face flange look like?
The raised face (RF) is the most common type of flange facing used. It is called a raised face flange because it has a raised surface above the bolting circle where the gasket is placed.
