Lap joint flanges, also known as loose flanges, are a type of flange that is often used in piping systems. These flanges are typically used when the piping system requires frequent dismantling, as they allow for easy alignment and disassembly of the pipe joints.

The lap joint flange consists of two parts: a stub end and a backing flange. The stub end is welded to the pipe, while the backing flange is free to rotate around the stub end. The backing flange has a flat face with bolt holes, which allows it to be bolted to another backing flange or to a flange on another piece of equipment.

One of the advantages of lap joint flanges is that they can be used with different materials of stub ends, allowing for flexibility in the piping system. They are also relatively low cost and easy to install.

However, lap joint flanges are not recommended for high-pressure or high-temperature applications, as they do not provide as strong a seal as other types of flanges. They are also more prone to leakage and require careful alignment to avoid misalignment during assembly.
