Lap Joint Flanges
Lap Joint Flanges(Loose Flanges) are used with a corresponding stub-end that “inserts” in the inside of the flange. The main benefit of this type of flange, is that once the pipe welds to the insert stub-end, the flange then can rotate for easier alignment of the bolting holes. However, lap joint flanges and their stub-ends’ ability to hold pressure is about the same as slip-on flanges. They are not suitable for situations with a high external or changing loads of force. They do provide an advantage in a piping system that needs frequent dismantling for inspection or to remove build-ups.
Lap Joint Pipe Flanges slide over the pipe and are most commonly used with Stub End Fittings. A pipe is typically welded to the Stub End and the Lap Joint pipe flange is free to rotate around the stub end. The benefit of this is that there will not be any issues with bolt hole alignment. Lap Joint pipe flanges are often used for applications that require frequent dismantling.
Red Earth Steels manufactures lap joint pipe flanges in all steel material grades, including carbon lap joint pipe flanges, stainless steel lap joint pipe flanges and alloy lap joint pipe flanges.
