F304 F316L UNS 31803 A105 Stainless/Duplex/Alloy/Carbon Steel LJF Lap Joint Flange
A lap-joint flange requires two piping components for each side of the flanged connection, a stub end and a loose backing flange. The loose backing flange fits over the outside diameter of the stub end, which is butt-welded to the pipe. The backing flange is not welded to the pipe, and it can be rotated, which is particularly useful when it is necessary to orientate flanges during erection.
Also, as the backing flange does not come in contact with the process fluid, it can made of a less corrosive-resistant material. For example, if the process is corrosive and requires the pipe to be of stainless steel, as in ASTM A312 TP316L, then the stub end must also be made of SS 316L; however, the backing flange can be made of the cheaper ASTM A105.
This method of jointing is not as robust as a weld neck flange but is superior to screwed, socket weld, and slip on connections; however, it is more expensive to execute, because it require a full-penetration butt weld and requires two components.
