ASME SA105 Carbon Lap Joint Flanges Manufacturer, Supplier, Exporter & Stockist in india

Carbon steel lap joint flanges are a type of flange used in piping systems where the bolt holes in the flange align with the pipe rather than the flange itself. They consist of two main components: a stub end and a backing flange. The stub end is typically made of carbon steel and is welded to the pipe, while the backing flange is a separate piece that slides over the pipe and stub end.

Material: Carbon steel lap joint flanges are typically manufactured from materials that conform to standards such as ASME SA105, which specifies the chemical composition and mechanical properties of carbon steel forgings. Dimensions: The dimensions of lap joint flanges, including the size, thickness, and bolt hole spacing, are specified in standards like ASME B16.5. These standards provide tables and diagrams to ensure compatibility with pipes and other flange components. Face Type: Lap joint flanges may have flat faces (FF) or raised faces (RF), depending on the application and sealing requirements. Connection: They are designed for use in applications where the flange needs to be easily aligned with the pipe during assembly. The stub end is typically welded to the pipe, and the backing flange is free to rotate and slide over the pipe, allowing for flexibility in positioning. Sealing: Lap joint flanges are often used in applications where the sealing is achieved by a separate gasket located between the stub end and the backing flange. This design allows for easy replacement of the gasket without disassembling the entire flange connection. Pressure Rating: The pressure rating of lap joint flanges depends on factors such as material, size, and design. It's crucial to select the appropriate flange based on the system's pressure and temperature requirements. Surface Finish: Lap joint flanges may have a smooth or serrated surface finish, which can affect gasket sealing and torque requirements during assembly.
