Lap joint flanges may be comprised of a style of flange connection employed in piping systems to join two pipes or fittings together. They consist of two separate components: and this prototype contain cap, stub end, and backing flange. The flat end is welded to the pipe, while the rotating flange is not welded, and allows for the alignment of the pipe molecule rings with the previously assembled pipeline. Lap joint flanges are mostly intended for those applications where disassembling and reassembling of the piping system would often take place, such as those in temporary or mobile installations. The mechanical features of the lap joint flanges, those being the weight, thickness, size and physical properties constitute a significant determine of their eligibility to particular positions. Accurate data on the mechanical properties of piping materials is essential for the making of designers and engineers for the correct and safe operation of the systems.
