SS 316 Lap Joint Flanges

The SS 316 Lap Joint Flange (LJ) is a specialized forging that is always used in conjunction with a Lap Joint Stub End. The flange itself is not welded or fixed to the pipe; instead, it is slipped over the pipe and is held in place by the Stub End, allowing it to swivel. This unique design simplifies the bolting process by allowing easy alignment of the bolt holes, making it highly valuable in systems requiring frequent dismantling for inspection or cleaning. Fabricated from Grade 316 stainless steel, these flanges, combined with the corrosion resistance of the stub end material, offer excellent performance in environments prone to corrosion. Zeron Fasteners supplies dependable SS 316 Lap Joint Flanges, manufactured to specifications like ASME B16.5, providing flexibility and cost efficiency in industrial piping.
