Stainless Steel Lap Joint Flange

Lap joint flanges are widely used in industrial piping systems to connect segments of pipelines together. A lap joint flange consists of two different parts that are joined together, the stub end and the backing flange. The stub end is a piece of pipe with a flared or enlarged end that fits into the bore of the backing flange. Stainless steel lap joint flanges are a popular type of lap joint flange for their durability, resistance to corrosion, easy maintain. In some cases, people use stainless steel stub end and carbon steel flange to reducing the pipeline cost

How Does a Lap Joint Flange Work?

The lap joint flange joint is designed to allow the stub end to rotate in the flange assembly, which allows for easier alignment of bolt holes during installation. The two flanges are not directly attached to each other, but rather the backing flange is bolted to another pipe or piece of equipment, and the stub end fits inside the flange. A lap joint gasket is then placed on the flat face of the backing flange, and the lap joint flange is then assembled by bolting the two flanges together.
