The flange depicted in the figure is a?

The flange depicted in the figure is a lap joint flange, which is designed to allow for easy installation and disassembly of piping systems. This type of flange consists of two primary components: a backing flange and a loose flange, which makes it particularly beneficial when alignment issues are a concern or in scenarios where frequent disassembly of piping is required without compromising the integrity of the joint.

Lap joint flanges are characterized by their rounded or flared edge, which allows the assembly to maintain a strong connection while also enabling the pipe to be rotated against the flange. This feature provides flexibility in positioning and facilitates easier maintenance.

In contrast, a socket weld flange entails a pipe that is inserted into the socket of the flange and is welded around the top, a blind flange serves to close off a piping system, and a threaded flange features internal threads for connecting to a pipe with external threads. The structural and functional properties unique to lap joint flanges distinguish them clearly from these other types.
