Lap Joint flanges are used on piping fitted with lapped pipe or with lap joint stub ends. The lap joint flange with the stub end assembly are normally used in systems requiring frequent dismantling for inspection and cleaning and where the ability to swivel flanges and to align bolt holes materially eases the erection of large diameter or unusually stiff piping. These flanges are also used in applications where there is a need to facilitate bolt alignment. These type of flanges are similar to slip-on flanges. The only difference is that it has a curved radius at the bore and face to accommodate a lap joint stub end. They may be used at all pressures and are available in a full size range. These lap joint flanges slip over the pipe, and are not welded. They are otherwise fastened to it. Here the bolting pressure is transferred to the gasket by the pressure of the flange against the back of the pipe lap.

ADVANTAGE OF LAP JOINT FLANGES:
Lap Joint flanges have certain special advantages over other flanges. These are as follows:

Lap Joint flanges have the freedom to swivel around the pipe. This facilitates the lining up of opposing flange bolt holes.
Lack of contact with the fluid inside the pipe leads to the greater durability of these flanges.
In piping systems which corrode or erode quickly, the lap joint flanges may be salvaged for re-use.
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.
They allow rotational alignment capability.

RFP India is a determined manufacturer of high quality of industrial lap joint flanges in India It is very much similar to slipon flange where it is having a radius at the junction of the bore and flange face that is for to create a lap stub end In the meantime the look on the stub end forms out by means of the gasket face on the flange Lap Joint flanges are being used in applications where parts of the piping systems need to be taking away from each other quickly and easily for inspection and replacement These lap joint flanges are being provided in fullscale range and are extensively used at all the pressures
