lap joint flange

A lap joint flange is a type of flange that is used to connect two pipes or fittings together. It consists of a flat circular plate with a small, raised collar or lip around the perimeter. The plate is bolted to a similar flange on the end of the adjacent pipe or fitting, with a gasket placed between the two flanges to provide a leak-tight seal.

The lap joint flange is unique in that it is not designed to bear any of the loads associated with pipeline pressure or stresses. Rather, it is used to facilitate easy assembly and disassembly of piping systems by allowing the bolted flange connections to be quickly disconnected and reconnected without disturbing the alignment of the pipes or fittings.

One common application for lap joint flanges is in piping systems where frequent maintenance or repairs are required. By using lap joint flanges, sections of pipe can be quickly and easily disconnected and replaced without the need to cut and weld the pipe.

Lap joint flanges are available in a variety of sizes and pressure ratings, and can be made from a variety of materials including carbon steel, stainless steel, and alloy steel. They are typically used in low-pressure applications and are not recommended for high-pressure systems or critical applications where leak-tight seals are required.

Lap joint flanges slide directly over the pipe and are most commonly used with stub end fittings. A pipe is usually welded to the Stub End and the Lap Joint pipe flange is free to rotate around the stub end. The benefit of this is that there will not be any issues with bolt-hole alignment. Lap Joint flanges are often used for applications that require frequent dismantling for inspection.
