James Duva, Inc. supplies lap joint flanges among other welded products. These are durable featuring simple installation.
Lap joint flanges, also commonly known as LJ Flanges, are used on piping fitted with lapped pipe or with lap joint stub ends.
Lap joint flanges have two parts, a stub end, and a loose backing flange. The stub end is butt welded to the pipe and the backing flange can freely move over the pipe. The backing flange can be made of a different material than stub material and normally. Often carbon steel is used to save on the cost. Lap flanges are used where frequent dismantling is required, and space is constrained.
Furthermore, a standard lap joint flange will typically have a longer hub length in comparison to a slip-on flange, but this is often considered unnecessary for many applications.
The lap joint flange is essentially identical to a slip-on flange with the exception that it has a radius at the intersection of the bore and flange face.
Used with lap joint stubs, lap joint flanges slide directly over the pipe. They are most often used for low alloy steel or carbon piping systems that are regularly dismantled for cleaning or inspection purposes.
Lap Joint flanges have the freedom to swivel around the pipe. This facilitates the lining up of opposing flange bolt holes.
So contractors often turn to lap joint flanges for their durability. As a result, they may be used in applications that often corrode or erode quickly. However, the lap joint flange may still be salvaged for another use. This is due to the lack of contact with the fluid material on the inside of the pipe.
